Should You Be Worried About Eye Floaters?

Visit Executive Park Eye Care in Colorado Springs

Eye floaters are actually more common that you may think. Many people notice specks or cobweb-like images moving around in their line of vision, at some point. Some even report experiencing a “snow globe effect” as if they are swatting at many imaginary bugs. Floaters may be an annoyance, but in most cases, they are harmless and merely a part of aging. Here are some answers to questions you may have about eye floaters including warning signs that something may be seriously wrong and requires immediate treatment by an eye care professional.

4 Common Questions Asked About Flashers & Floaters

Q: Why is it that when I wake up during the night and I lay there with my eyes closed I have a white flash like someone turning a white page in a book quite fast?

  • A:Often when we close our eyes we experience entopic phenomenon, which are visual effects of components within our eye. Specific aspects of the eye can produce images that are specific to each individual. Small floaters can be shadows of objects in the retina such as red blood cells, or white blood cells moving through blood vessels. If the floaters and flashes are visible in daylight, and become frequent, you will want to come in for an examination to ensure your eyes are healthy. Flashing lights and floating spots can be an early signs of retinal problems.

Q: I suddenly see random wavy lines, zig-zagging, and/or blotches of missing vision in my vision that last for no more than 30 minutes, should I be concerned?

  • A: You may have just experienced an ophthalmic migraine or a migraine with aura. Usually, these are harmless and indicates some sort of stress. However, it is a diagnosis of exclusion, meaning we need to always make sure that isn’t any other ocular concern within the eye itself that may be causing your symptoms. It is a good idea to make an appointment within a few days to have your vision and eye health examined.

Q: Whenever I close my eyes, I see flashes of light in my vision, should I be concerned?

  • A: Flashes of light in your vision could be a very dangerous sign! Something is tugging at your retina and eliciting these flashes of light. Sometimes it could be the vitreous humor pulling at the retina in aging vitreous degeneration, but sometimes it could mean a dangerous retinal tear or detachment. Detachments need to be treated within 24 hours for the best prognosis in preventing permanent vision loss.

Q: I have “spots” floating around in my eye. Should I be worried?

  • A: Spots and floaters are usually harmless. However, in some cases it can be a sign of a retinal detachment or bleeding. Anyone experiencing symptoms of flashing lights and flashing spots should contact our office immediately for a detailed eye exam.

What are eye floaters?

Eye floaters are collagen deposits inside the vitreous humor that fills the space between the lens and retina of your eye. As you age, the vitreous, which is made up of this gel-like protein substance, begins to dissolve and liquefy, creating a more watery consistency. Floaters appear when the collagen fibrils and vitreous membrane become disturbed and go into your line of sight. A posterior vitreous detachment is a common age related change that causes a sudden large floater to occur. Floaters can range in size, shape and consistency and are often more visible when looking at a white screen or clear blue sky.

What is the vitreous?

The vitreous functions to maintain the round shape of your eyeball. It assists with light refraction and acts as a shock absorber for the retina.

How do floaters develop?

As mentioned above, aging of the vitreous can cause it to liquefy, shrink and become stringy or strand-like. As the vitreous is normally transparent, when strands develop they cast a shadow on your retina, which in turn causes floaters to appear in your vision.

What will I see if I have floaters?

Eye floaters can appear in your vision as threads, fragments of cobwebs or spots which float slowly in front of your eyes. You’ll also notice that these specks never seem to stay still when you try to focus on them. Floaters and spots create the impression that they are drifting and they seem to move when your eye moves.

Who is at risk for developing floaters?

Floaters are quite common particularly in individuals that are elderly, diabetic, near-sighted or anyone who has had cataract surgery.

Are floaters dangerous and do they need treatment?

In many cases, floaters are simply an annoyance and can be left alone. Sometimes they will improve over time. In some cases though, floaters can be so distracting that they can block vision and consequently interfere with daily activities and functioning. If you experience a sudden onset of floaters, if they are accompanied by flashes of light or vision loss, if you have pain or you have just experienced eye surgery or trauma, floaters could indicate a serious eye problem that requires immediate medical attention. There are a number of eye disorders associated with eye floaters including retinal detachment, retinal tear, vitreous bleeding, vitreous and retinal inflammation or eye tumors, all of which require medical treatment to avoid vision loss. If you have sudden onset of new floaters, do not wait to book an appointment with your eye doctor to confirm if the floaters are benign or need immediate surgical treatment.

8 Tips to Relieve Winter Dry Eyes

Whether you live in a climate with cold winter weather or you are planning a ski trip up north, winter can be a challenge if you suffer from dry eyes. Dry, cool air, cold winds and even drier indoor heating can cause eye irritation, burning, itchiness and redness, and sometimes even excessively watery eyes as more tears are produced to compensate for the dryness. Many people have a chronic feeling that they have something in their eye and some even experience blurred vision. These symptoms can be debilitating!

Dry eyes is one of the most common complaints eye doctors get from patients during the winter season, especially in the cooler climates. That’s why we’d like to share some tips on how to relieve dry eye discomfort, and how to know when your condition is serious enough to come in for an evaluation.

Tips to Relieve Winter Dry Eyes:

  1. Keep eyes moist using artificial tears or eye drops. You can apply these a few times each day when the eyes are feeling dry or irritated. If over-the-counter drops don’t help or if you have chronic dry eyes, speak to your eye doctor about finding the best drops for you. Since not all artificial tears are the same, knowing the cause of your dry eye will help your eye doctor determine which brand is best suited for your eyes.
  2. Use a humidifier to counteract the drying effects of indoor heaters or generally dry air.
  3. Point car vents or indoor heaters away from your face when the heat is on. Try to keep your distance from direct sources of heating, especially if they blow out the heat.
  4. Drink a lot! Hydrating your body will also hydrate your eyes.
  5. Protect your eyes outdoors with sunglasses or goggles – the bigger the better! Larger, even wrap-around glasses as well as a hat with a wide brim will keep the wind and other elements out of your eyes. If you wear goggles for winter sports, make sure they fit well and cover a large surface area.
  6. Soothe dry eyes using a warm compress and never rub them! Rubbing your eyes will increase irritation and may lead to infection if the hands are not clean.
  7. Give your eyes a digital break. People blink less during screen time which is why extensive computer use can lead to dry eyes. Follow the 20/20/20 rule by taking a break every 20 minutes to look 20 feet away for 20 seconds and make sure you blink!
  8. For contact lens wearers: If you wear contact lenses, dry eyes can be particularly debilitating as the contact lenses can cause even further dryness and irritation. Contact lens rewetting drops can help your eyes feel better and may also allow you to see more clearly. Not all eyedrops are appropriate for use with contact lenses, so ask your optometrist which eyedrop is compatible with your contacts and cleaning solution. If rewetting drops don’t help, consider opting for glasses when your dry eyes are bad, and speak to your optometrist about which brands of contact lenses are better for dry eyes. Many people find dry eye improvement when they switch to daily single use contact lenses.

Chronic Dry Eyes or Dry Eye Syndrome

Dry eye syndrome is a chronic condition in which the eyes do not produce enough tear film, or do not produce the quality of tear film needed to properly keep the eyes moist. While winter weather can make this condition worse, it is often present all year round. If you find that the tips above do not alleviate your discomfort or symptoms, it may be time to see a optometrist to see if your condition requires more effective medical treatment.

Diabetes and Your Eyes

Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.

Executive Park Eye Care - Local Vision Center in Colorado Springs, Colorado

Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.

“In 2014 alone, eye doctors found diabetes-related manifestation in 240,000 patients who were not aware they had diabetes, leading to a prompt diagnosis and care, which minimizes the risk of complications,” says AOA President Andrea P. Thau, O.D.

What is Diabetes?

Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.

How Does Diabetes Affect The Eyes?

Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.

In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.

The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.

Diabetic Retinopathy

As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.

The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.

Local eye care, eye doctors in Colorado Springs, Colorado

Signs and Symptoms of Diabetic Retinopathy

The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:

  • Blurred or fluctuating vision or vision loss
  • Floaters (dark spots or strings that appear to float in your visual field)
  • Blind spots
  • Color vision loss

There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.

A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.

Retinal Detachment

Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.

Diabetic Macular Edema (DME)

Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.

Treatment for Diabetic Retinopathy and Diabetic Macular Edema

While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.

Prevent Vision Loss from Diabetes

The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.

Have an Eye Safe Halloween

Brush Up Before You Dress Up

Halloween is one of the most fun times of the year for children and adults alike. When else do you get to dress up as anyone (or anything) you want, socialize with friends and eat lots of treats? Nevertheless, lurking behind those costumes and all that fun are some hidden dangers that you need to be aware of and many of them could affect your eyes and vision. Brush up on these preventative measures to help you and your children to stay safe and enjoy the holiday.

Masks

Masks can really make or break a costume but they can also increase danger, especially for children. Masks that block visibility or the ability to breathe can be extremely dangerous. You want to make sure that you and your children have a complete, unobstructed visual field, especially if they will be crossing streets.

Facepaint

Facepaint can be a great alternative to a mask, but it comes with its own set of precautions. Buy face paint that is hypoallergenic and do a spot test to make sure there is no allergic reaction anyway. Make sure to keep the paint out of the eyes and be careful during application especially with sharp, pointed brushes that can scratch the eye. If face paint or any other substances get into the eyes, immediately flush the eyes thoroughly with saline or water as chemical splashes can cause significant eye damage within minutes. This should be done before consulting your eye doctor. If irritation persists however, it should be looked at by an eye doctor.

Props

Try to avoid costumes with sharp or pointed props such as spears, swords or guns that shoot. Warn children at play to never point an object at a person’s head or eyes.

That goes for spray cans of silly-string, as well. The chemicals in these products can be very dangerous to the eyes, risking chemical conjunctivitis and serious eye irritation. The pressure at which the string is sprayed can also cause eye damage including a corneal abrasion (a scratch to the surface of the eye) if sprayed into the eye at a close range. These popular Halloween products should be avoided or, if necessary, children should be seriously cautioned not to spray anyone near the neck or face.

Visibility

Speaking of sight, you want to make sure that you and your children are visible to motorists on the streets. Chose brightly colored costumes and carry a flashlight to increase visibility. Consider adding some reflective tape to the costume or props as well.

Decorative Contact Lenses

Decorative contact lenses can look great, but they can cause serious damage. That’s why even non-corrective contact lenses are considered a medical device, which must be approved by the Food and Drug Administration or Health Canada, and require a prescription from an eye doctor.

Never buy fashion, decorative, cosmetic, colored or theater contact lenses (or any other name that they go by) from a beauty or costume supply store or any unauthorized vendor. You should purchase them only with a prescription from an eye doctor after an eye exam to measure your eye and assess your eye health.

Why?

Contacts obtained through an unauthorized source may not be safe to wear. They might cause a corneal abrasion, allergic reactions, infections and decreased vision which can even lead to blindness.

Plus, your optician or eye doctor will give you instructions for proper use and hygiene such as washing your hands, storing and cleaning the lenses properly and removing them as prescribed.

If you are wearing any type of contact lenses and you notice redness, pain or blurred vision, take them out immediately. If symptoms persist, see your eye doctor as soon as possible.

Stay Safe

Don’t make Halloween into a truly scary holiday. Take heed of these potential dangers and take the necessary precautions to stay safe. Happy Halloween!

Is Your Teen Ready for Contacts?

Many teens who wear glasses are eager to try out contact lenses for convenience, fashion or to just provide another option for vision correction. For teens who feel self-conscious in their glasses, contact lenses can be a way to improve self-esteem. Young athletes and swimmers find that contacts are an excellent option for sports, especially as younger kids are becoming involved in travel sports and club teams outside of school.

While contacts might appear to be the perfect solution for teens that need corrective eyewear, they are a convenience that comes with a lot of responsibility so it’s not a decision to take lightly. Improper use of contact lenses can cause severe discomfort, infections, irritation and, in the worst cases, eye damage or even permanent vision loss.

“With Privilege Comes Responsibility”

Contact lenses are a medical device and should always be treated as such. They should never be obtained without a valid contact lens prescription from an eye doctor, and always purchased from an authorized seller. Among other issues, poor fitting contact lenses bought from illegitimate sources have been known to cause micro-abrasions to the eyes that can increase the risk of eye infection and corneal ulcers in worst case scenarios.

Particularly when it comes to kids and teens, it is best to purchase contact lenses from an eye doctor as they possess the expertise to properly fit contact lenses based on the shape of the eye, the prescription, the lifestyle of the child and other factors that may influence the comfort, health and convenience of contact lens use.

There is some debate over the recommended age for kids to start considering contact lenses. While some experts will say the ideal age is between 11 and 14, there are many responsible children as young as 8 or even younger who have begun to successfully use them. When children are motivated and responsible, and parents are able to ensure follow-up to the daily regimen, earlier contact lens use can be a success. A good measure of whether your child is responsible enough to use contacts is whether they are able to keep their room clean, or maintain basic hygiene like brushing teeth regularly and effectively.

When you think your child might be ready, you should schedule an appointment with your eye doctor for a contact lens exam and fitting. The process will take a few visits to perform the exam, complete a training session on how to insert, remove and care for lenses, then to try out the lenses at home and finally reassess the comfort and fit of the contacts. You may try out a few varieties before you find the best fit.

What Kind of Contact Lens Is Best for My Teen?

The good news is that contact lens use has become easier than ever, with safety, health and convenience being more accessible as technology improves. There are a number of options including the material used to make the lenses (soft or rigid gas permeable), the replacement schedule (if disposable, how often you replace the pair – daily, weekly, biweekly or monthly) and the wear schedule (daily or extended overnight wear).

Single use, daily disposable lenses have become very popular, particularly with younger users, because they are easy to use, requiring no cleaning or storing, and therefore they reduce the risk of infection and misuse. You simply throw out the lenses at night and open a new one in the morning. Your eye doctor will be able to help you and your teen determine the best option.

Tips for Contact Lens Wearers

Following are some basic contact lens safety tips. If your teen is responsible enough to follow these guidelines, he or she may be ready for contact lens use:

  1. Always follow the wearing schedule prescribed by your doctor.
  2. Always wash your hands with soap before applying or removing contact lenses.
  3. Never use any substance other than contact lens rinse or solution to clean contacts (even tap water is a no-no).
  4. Never reuse contact lens solution
  5. Follow the eye doctor’s advice about swimming or showering in your lenses
  6. Always remove your lenses if they are bothering you or causing irritation.
  7. Never sleep in your lenses unless they are extended wear.
  8. Never use any contact lenses that were not acquired with a prescription at an authorized source. Never purchase cosmetic lenses without a prescription!

Contact lens use is an ongoing process. As a child grows, the lens fit may change as well, so it is important to have annual contact lens assessments. Plus, new technology is always being developed to improve comfort and quality of contact lenses.

Contact lenses are a wonderful invention but they must be used with proper care. Before you let your teen take the plunge into contact lens use, make sure you review the dangers and safety guidelines.

Executive Park Eye Care Becomes a Foundation Fighting Blindness Partner for Retinal Health

Colorado Springs, Colorado (May 12, 2016) — Committed to providing resources and support to patients living with retinal degenerative diseases like macular degeneration and retinitis pigmentosa, Executive Park Eye Care in Colorado Springs has become a Foundation Fighting Blindness Partner for Retinal Health.

As a national patient outreach and education initiative, the Partners for Retinal Health program involves dedicated ophthalmology and retinal specialist practices interested in offering their patients the latest information about retinal diseases, cutting-edge research, and living with low vision.

“By partnering with dedicated practices across the country, we’re striving to raise awareness about vision-robbing retinal diseases that afflict more than 10 million Americans,” says Angela Vasquez, senior director of marketing and communications for the Foundation Fighting Blindness.

“Through the program, we’re educating patients about their conditions and providing the critical resources necessary to help them lead full lives, as our funded research moves the needle toward treatments and cures for these disabling eye diseases.”

As a Partner for Retinal Health, Executive Park Eye Care can better equip existing and newly diagnosed retinal disease patients with relevant information about research advancements and coping, and refer them to a local Foundation Fighting Blindness chapter that facilitates networking opportunities with others living with vision loss.

“Becoming a Foundation Fighting Blindness Partner for Retinal Health is a natural fit for our practice because we’re committed to helping our patients understand their conditions and live independently despite progressive vision loss from retinal disease,” says Dr. Jeanne Derber of Executive Park Eye Care.

About the Foundation Fighting Blindness

The Foundation Fighting Blindness is a national non-profit organization driving the research that will lead to prevention, treatment, and cures for retinitis pigmentosa,macular degeneration, Usher syndrome and the entire spectrum of retinal degenerative diseases that affect more than 10 million Americans.

Since 1971, the Foundation has raised more than $500 million as the leading non-governmental funder of retinal research. Breakthrough Foundation-funded studies using gene therapy have restored significant vision in children and young adults who were previously blind, paving the way for additional clinical trials to treat a variety of retinal degenerative diseases.

About Executive Park Eye Care

At Executive Park Eye Care, we help to preserve and improve the vision of each of our patients. Our licensed optometrists, certified opticians, and highly trained technicians are among the finest, and we work hard to be your trusted choice in eye care professionals. From comprehensive eye exams, contact lens services, low vision evaluations, and an in-house optical department, Executive Park Eye Care is your partner in better vision.

Why Do We Need Glasses?

clipart-010The most well-known part of a comprehensive eye exam is the basic vision test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:

Myopia or nearsightedness:
In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

Hyperopia or farsightedness:
Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

Astigmatism:
Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

Presbyopia:
Presbyopia is an age-related condition which usually begins to appear sometime after 40. As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances. However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents. In these instances people with hyperopia could use glasses at any distance.

If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.

Eye Safe Toys and Gifts for This Holiday Season

 

EyeSafetyChristmasGifts‘Tis the season for giving, and parents, grandparents, family and friends need to know which toys and games to leave off the list because they can pose a risk to children’s health and eyesight. Last year nearly 252,000 emergency visits were due to toy-related injuries, almost half of which were to the head or face. Further, about 1 in 10 children’s eye injuries treated in the emergency room can be traced back to toys, most of which occur in children under 15 years of age.

The most common types of eye injuries that occur from toys can be anything from a scratch on the cornea (the front surface of the eye) to very serious injuries that can threaten vision such as traumatic cataracts, corneal ulcers, bleeding inside the eye and retinal detachment.

Most of these injuries can be prevented by taking the proper measures to evaluate the safety of gifts before they are purchased and to supervise children during any play with toys that could have the potential to cause damage or harm.

Here are some tips on how to select safe toys for children this holiday season:

  1. Check age recommendations on all toys to make sure they are age appropriate and suitable for the child’s maturity level. If younger siblings are present, ensure that any toys made for older children are kept out of reach.
  2. When possible, check toys for a seal of approval that the product meets national safety standards from a toy safety testing organization such as the American Society for Testing and Materials (ASTM) or the Canadian Toy Testing Council.
  3. Do not purchase toys that have a projectile or sharp, protruding parts. Toys such as darts, guns, arrows or sharp propelling toys can cause serious eye injuries that can lead to permanent eye damage and even vision loss. Even high-powered water guns such as super soakers or soft foam dart guns can cause significant damage when shot at close range.
  4. Purchase safety eyewear with polycarbonate lenses to accompany sports equipment, chemistry sets or woodworking tools. Speak to your optometrist to learn more about the best option for your child’s hobby of choice.
  5. Check that toys with sticks or handles such as swords, fishing rods, pogo sticks, brooms or pony sticks have rounded edges or handles and avoid or supervise use with little children.
  6. Any toys or devices that have a laser or bright light (such as laser pointers or flashlights which are sometimes used by kids to play laser tag) can be dangerous. Bright lights such as those produced by high-powered flashlights can cause temporary vision loss that can lead to a risk of a fall or accident. Further, laser pointers are not safe for use by children as the light intensity can cause permanent vision loss if shined in someone’s eyes.

When purchasing a toy for a child that is important to you, make sure you are considering what is most important – their safety. Ask us if you have any questions about the eye safety of a toy or gift you are considering.

Have you ever thought about how vision works? Seeing is an incredible eyeball drawinggift made possible by a system in which the eye and the brain process visual information from the outside world. If any step of that process does not function properly, vision will be impaired.

Similar to a camera, the eye transmits light from the world around us into an image that we can perceive. Certain parts of the eye even function like the different parts of a camera such as the shutter, the lens and film (if we can hearken back to the days when we used film in cameras). Here is a quick breakdown of the fascinating way our eyes and brain enable us to see and experience the world around us:

The Vision Process

Light reflected from an object in our field of view is gathered by the cornea which is essentially the clear “window” to our eye. The cornea then refracts the light rays through the pupil (the center of the iris where light enters the eye). The iris, which like the shutter of a camera will enlarge and shrink based on how much light is coming in, then passes the image onto the crystalline lens. Just like a camera lens, the lens in the eye focuses the light rays, projecting them to a point at the back of the eye called the retina, where the image will appear upside down. The retina contains a thin layer of color-sensitive cells called rods and cones that perceive color.

From the retina, the visual signals travel to the brain via the optic nerve. The brain receives information from both eyes and must then converge the images (and flip them right side up) to get a complete picture.

Vision Problems

A breakdown in vision can happen at any point in this process. From the muscles that control the eyes, to the parts within the eye, to the pathway to the brain. Sometimes vision impairment is due to technical problems with the eye receiving the information and passing the signal on, such as convergence insufficiency (inability to coordinate the eyes to converge on one point), myopia (nearsightedness) or cataracts (clouding of the lens).

Other times, the eyes might work perfectly, but there is a problem with the brain interpreting the signals it receives. In these cases we can’t “see” in the traditional sense, because our brains aren’t able to properly “read’ the signals or we don’t know what we are looking at. This is the case for some learning disorders that are caused by the visual processes in the brain such as dyslexia.

As you can see, vision is quite a complicated process. A simple vision exam isn’t always able to determine vision problems, especially in children which is why it is so important to have regular comprehensive eye exams, to measure the health of the eye and all of its parts.
