Optometrists are proud members of the healthcare community. Here are some tips of the trade to help you achieve eye health wellness.
- Hindsight is 20/20: know your family history. Genetics can play a large role in determining your risk of developing certain eye conditions. Your own lifestyle choices, like maintaining your overall health and getting regular exercise, can help too.
- Don’t turn a blind eye to wearing sunglasses, including even the youngest members of your family. The majority of our lifetime exposure to UV occurs before age 20. It’s never too late to start – it can minimize progression of cataracts and macular degeneration, and help with fine lines and wrinkles too!
- Are your eyes bigger than your stomach? Maintain a well-balanced diet including leafy green vegetables to help defend against macular degeneration. Foods rich in omega 3 like salmon have been linked to improving dry eye.
- Something we should see eye to eye on is the need to quit smoking. Smoking negatively impacts your health in a number of ways including increasing your risk of developing cataracts, macular degeneration and dry eye.
- Do you have eagle eyes? You may think you see well when really your vision could be optimized for your work and play. Having appropriate eyewear for your needs improves your quality of life, safety, and productivity. On the flip side, just because you’re aging doesn’t mean you shouldn’t see well!
Many ocular diseases have no signs or symptoms but can be detected early on. Visit your Optometrist regularly – we look forward to seeing you!
Dr. Rebecca Chippior is an Optometrist and is the owner of St. Lawrence Optometry with two locations in Kingston.
Everyone seems to be staring at a screen these days, whether their computer, their smartphone or another digital device. The stress it puts on your eyes can cause a condition called “digital eye strain” (DES) or “computer vision syndrome” (CVS). Symptoms include eye fatigue, dry eyes, blurred vision, headaches, neck and shoulder pain, red eyes, and eye twitching.
How To Protect Your Eyes While You Work
Below are a few things you can do to lower your risk or mitigate any discomfort associated with DES.
1. See your eye doctor for a comprehensive eye exam
This is one of the most important things you can do to prevent or treat symptoms associated with computer vision syndrome. During your eye doctor’s appointment, make sure to speak with Dr. Rebecca Chippior about your working habits, including the frequency and length of time you use a computer and other devices at work and at home.
If you get a chance before you come, measure the distance between your eyes and your computer screen and bring that information to the optometrist, so that you can get your eyes tested for that specific working distance.
Computer vision syndrome may be exacerbated by an underlying dry eye disease, which can be diagnosed and treated at our eye clinic in Kingston.
Sometimes people who have good visual acuity assume they don’t need any glasses. However, even very mild prescriptions can improve eyestrain and curb fatigue when working at a computer.
2. Good lighting is key
Excessively bright light, whether due to outdoor sunshine coming in through the window or harsh interior lighting, is a common cause of eyestrain. When using your computer, your ambient lighting should be about 50% dimmer than what is typically found in most offices.
You can reduce exterior light by closing drapes, blinds or shades and diminish interior illumination by using fewer or lower intensity bulbs. Computer users often find that turning off overhead fluorescent lights and replacing them with floor lamps is easier on their eyes.
3. Minimize glare
Eyestrain can be aggravated by glare from light reflecting off surfaces including your computer screen. Position your computer so that windows are neither directly in front of nor behind the monitor, but rather to the side of it. Consider installing an anti-glare screen on your display. If you wear glasses, get anti-reflective (AR) coating on your lenses to reduce glare by limiting the amount of light that reflects off the front and back surfaces of your lenses (more on that below.)
4. Upgrade your display
If you have a CRT (cathode) screen on your monitor, consider replacing it with a flat-panel LED (light-emitting diode) screen that includes an anti-reflective surface. Old-school CRT screens can be a major cause of computer eye strain due to the flickering images.
For your new flat panel desktop display, choose one with a diagonal screen size of at least 19 inches, and the higher the resolution, the better.
5. Adjust display settings for added comfort
Adjusting your computer display settings can help decrease eye strain and fatigue too.
- Brightness: Adjust your device’s brightness to match the luminance around you. If the white background of this page looks like a light source, then it should be dimmed. However, if it appears dull and gray, it may not provide enough contrast, which can make it hard to read.
- Text size: Adjust the text size for maximum eye comfort, particularly when reading, editing or writing long documents. Increase the size if you find yourself squinting, but bigger isn’t always better, since overly large text display may force your eyes to track back and forth too quickly for comfort.
- Color temperature: This refers to the spectrum of visible light emitted by a color display. Blue light is short-wavelength visible light, whereas orange and red are longer wavelength hues. Exposure to blue light helps keep you alert but tends to cause eye fatigue after a while; yellow to red tints are more relaxing and may be better for long-term viewing, especially at night. Many devices allow the user to adjust the color temperature.
6. Get computer glasses
Nearly 70% of North Americans experience digital eye strain related to prolonged use of electronic devices. To combat these effects, St Lawrence Optometry recommends digital protection coatings, which act as a shield to cut the glare and filter the blue light emanating from digital screens and artificial light.
For the greatest eye comfort, ask Dr. Rebecca Chippior for customized computer glasses, which feature mildly tinted lenses that filter out blue light. These can be made with or without prescription vision correction, for the benefit of those with 20/20 vision or contact lens wearers, though many people with contacts actually prefer to have alternative eyewear to use when their lenses become dry and uncomfortable from extended screen time.St Lawrence Optometry can help you choose from a vast array of effective optical lenses and lens coatings to relieve the effects of digital eye strain.
7. Don’t forget to blink
When staring at a digital device people tend to blink up to 66% less often, and often the blinks performed during computer work are only partial which aren’t as effective at keeping the eyes moist and fresh feeling. Making a conscious effort to blink more while working or watching can prevent dryness and irritation.
8. Exercise your eyes
Another cause of computer eye strain is focusing fatigue. Look away from your computer every 20 minutes and gaze at an object located 20 feet away, for a minimum of 20 seconds. This “20-20-20 rule” is a classic exercise to relax the eyes’ focusing muscles and reduce computer vision syndrome.
The steps above don’t require a tremendous amount of time or money to be effective. Contact St Lawrence Optometry in Kingston to make an appointment with Dr. Rebecca Chippior and learn how the right eye drops, eye exercises, computer glasses, or AR coatings can improve eye comfort, reduce computer vision syndrome and potentially lead to increased productivity and job satisfaction.
Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.
Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness:
- Age-related macular degeneration (AMD)
- Diabetic retinopathy
The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.
How Obesity Contributes to Eye Disease
A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list.
Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss.
The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.
Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair!
Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.
A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease
Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.
An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases.
We Can Help Keep Your Eyes Healthy in Kingston
While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. Rebecca Chippior can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.
If you have any questions or concerns regarding your vision or eye health, don’t hesitate to call St Lawrence Optometry — we’re here for you.
Playing outside in a snowy winter wonderland can be magical. Under clear skies in the sunshine, the soft white landscape becomes just about irresistible, whether at home or travelling on a winter-weather get-away.
Before you let your children run outside to build the most adorable snowman or fling themselves onto the ski slopes, make sure their eyes are well protected. Sun and snow can be a dangerous combination for both the eyes and skin.
Sunlight Reflected in the Snow
We all know why we need to wear sunglasses and sunscreen in the summer. Winter, however, can be deceiving. It’s an illusion to assume that we are safe from sunburns during the colder season.
Snow acts as a powerful mirror for sunlight and magnifies the effects of UV rays which would otherwise be absorbed by the ground. As a result, the eyes are exposed to both the UV radiation bouncing back from the snowy carpet and the rays shining down directly from the sun.
If your family is skiing or snowboarding up in the mountains, you need to be even more careful! UV rays are more powerful at higher altitudes. Another important factor to remember is that ultraviolet radiation penetrates through clouds, so even if the sun is hidden behind them, it can still damage your eyes.
Can I Get Sunburned Eyes?
As you may have already guessed, yes —it is possible to get sunburned eyes. The condition is called snow blindness, or photokeratitis. Although most people do not actually experience permanent vision loss, photokeratitis is usually painful, causes extreme sensitivity to light, and can take up to two weeks to fully heal.
A single day of playing outside in the snow and being exposed to intensive sun glare can be enough to cause snow blindness— though usually with a delay of several hours following sun exposure. What’s worse, if the eyes are repeatedly sunburned there is a risk of long-term damage.
Symptoms of Snow Blindness
Just like a typical skin sunburn appears only after having been exposed to the sun’s rays, the same is true for the eyes. One sign of overexposure to UV is a stinging or burning sensation in the eyes, or a feeling of having sand in your eyes after a day spent in the snow.
When eyes are sunburned, they become highly sensitive to light, making it difficult to be outside. Other symptoms include blurred vision, watery eyes, and swollen eyelids. In rare cases, photokeratitis can even cause temporary vision loss, but it doesn’t usually last longer than a day or two.
How Do I Protect My Eyes From Sunburn?
Prevent overexposure to sunlight by wearing sunglasses that absorb at least 95% of ultraviolet radiation when you go outside, no matter what time of year it is. An even more effective solution for winter activities is to strap on a pair of well-fitting UV protective sports eyewear, such as ski goggles. Wrap-around styles are ideal because they stay on even when you’re active, and block the sun’s rays from entering your eyes from the sides too.
For winter sports lovers, there are plenty of good reasons to wear protective eyewear, and what works well in sports can be good for play as well.
How Can I Treat Sunburned Eyes?
It’s after the fact, and you’re suffering from photokeratitis… now what? Give your eyes a rest.
- Stay out of the sun for a few days until the symptoms die down.
- You may find it comforting to wear sunglasses even when indoors.
- For additional relief, place a cool, damp cloth over the closed eyelids while resting.
- Don’t wear contact lenses until the eyes return to normal.
- Artificial tears can help keep the eyes moistened, soothe discomfort and promote healing. However, it’s important to consult an eye doctor before running to the pharmacy, since some eye drops are not well-suited for this condition. You can give us a call at 613-546-5744.
Now that you know the risks and precautions to take, you’re all set to enjoy the winter wonderland! Dr. Rebecca Chippior at St Lawrence Optometry is happy to help you protect yourself and your family from snow blindness, and offers expert treatment for sunburned eyes.
Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it’s important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor.
But First, What Is Diabetes?
Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn’t produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.
Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.
What’s the Link Between Vision and Diabetes?
Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels.
If you start to notice blurry vision, make an appointment with Dr. Rebecca Chippior as soon as possible.
The 3 Ways Diabetes Impacts Vision
While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective.
Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss.
Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.
Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.
Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.
The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact St Lawrence Optometry in Kingston to set up your eye doctor’s appointment today.
