Top 5 Tips: Are You Using Your Contacts Properly?

As days get longer, sunlight gets warmer, and excitement for summer vacation grows, many of us like to trade in our glasses for the convenience and look of contact lenses. Review our top 5 tips on how to use and care for your contact lenses properly!

1. Invest in quality contact lenses that are safe for your eyes. There are countless brands of lenses, each with different sizes, shapes, moisture, breathability, stiffness, and ability to protect against UV. Did you know the power in your contact lens is rarely the same as your glasses? Only your optometrist can fit you with the best lenses that are crisp, comfortable, and healthy for your eyes’ unique features. Dry eyes with lens wear is not normal, and your doctor can explain different ways to prevent this.

2. Clean and replace them as your doctor directs. Your eye needs to breathe! An old or dirty lens can starve your eye of oxygen, causing inflammation and discomfort. Worse, it can become a breeding ground for bacteria. Would you re-wear used socks or underwear? Well, same goes for your contacts! Depending on the brand, your doctor may recommend that you replace them daily, bi-weekly, or monthly. Some lenses must be rubbed and stored with a specific cleaning solution. If you use a storage case, wash it daily and swap it out for a new one every 3 months to prevent a build-up of bacteria.

3. Never over-wear or sleep in your lenses. Contacts should not be worn for more than 12-14 hours per day, and it is always a good idea to take a break from them at least two days of the week. Sleeping – even napping – in your lenses significantly increases your risk of infection, which can lead to permanent vision loss in severe cases. For days when your eyes are red, feeling irritated, or when you are sick, you should not wear your contacts as it puts you at greater risk of infection and inflammation.  

4. Always wear sunglasses over your lenses. You wouldn’t apply sunscreen just on your arms while leaving your back exposed, would you? While some (not all) contact lenses have UV protection, contact lenses only cover a small portion of the eye. This still leaves the rest exposed to UV damage. A stylish pair of high definition polarized sunglasses, such as Maui Jim®, cuts glare and ensures your eyes are fully protected.

5. Avoid exposing your lenses to water. Water can be full of chemicals and bacteria that can adhere to the contact lens. Ideally, swimming with prescription goggles is best for your eyes. However, if you must, wear disposable contacts with goggles, then replace the lenses with a fresh pair immediately after swimming.

Are Our Eyes a Window Into Detecting Early Dementia?

Did you know that over 170 systemic diseases can manifest in the eye? Just by looking into your eyes, your doctor can help detect things such as diabetes, high blood pressure, high cholesterol, thyroid conditions, autoimmune disease, anemia, multiple sclerosis, stroke, and cancer. With today’s rapidly growing technology, scientists may soon be adding Alzheimer’s Disease to that list.

Alzheimer’s disease (AD) is the most common form of dementia, and 1 in 5 will suffer from it by age 85. Researchers have found that in AD, plaques of an extracellular deposit called amyloid-beta accumulate in the brain. Since the eye is an extension of the brain’s neural tissue, these plaques are also found to build up inside the eye’s retinal neurons.

A special type of low-cost and non-invasive retinal imaging called scanning laser ophthalmoscopy can be used to detect amyloid-beta in the eye. One study showed that this method detected 4.7x more amyloid-beta in retinas of patients with AD. It’s a promising prospect for early detection of AD before clinical signs, such as memory loss, begin to appear. This would open doors for early, preventative treatment.

Research still has a long way to go, however, since studies are still ongoing to determine how accurate this scan would be in diagnosing AD. We wonder how many other neurological conditions might also show up in the eye; perhaps this discovery is only the beginning!

5 Tips For Taking Care Of Your Baby’s Eyes

We always recommend a baby’s first eye exam to be at 6 months old. At this age, their visual skills are rapidly developing, and it is important to ensure they are seeing well so that they can learn and explore the world around them. A great question we always get is how we can do eye tests on someone who doesn’t know their 123s or ABCs. Of course, we modify our infant exams to incorporate fun lights, sounds, and toys to check eye alignment and their ability to follow moving objects. We also use patterns to check their ability to see detail, as babies will naturally pay attention to new and interesting patterns. Lastly, we use lights to look at their eye health in a very non-invasive way.

Here are my five tips for taking care of your baby’s eyes:

1. Baby sunglasses are a must! Up to 80% of a person’s lifetime exposure to damaging UV radiation occurs before age 18. Protect your kid’s eyes as soon as possible, whenever they are outdoors at all times of the year.

2. To aid visual development, keep reach-and-touch toys within your baby’s focus of about 8 to 12 inches, and help them explore different shapes and textures with their fingers. Remember daily tummy time as it is crucial for developing posture, vision, and motor coordination. Once mobile, give them the freedom to crawl and explore. Stay tuned for our next blog on primitive reflexes, which newborns have that set the stage for proper motor development!

3. Watch your baby’s eyes carefully, checking to see if they recognize and follow objects or faces. If you ever see an eye turn in or out (i.e. crossed eyes), bring them to see an optometrist.

4. Make eyelid hygiene a part of their daily routine. Removing debris and crusting will make their eyes more comfortable and reduce the risk of infection. Start with a soft washcloth dampened with warm water. With their eyes closed, gently wipe from the inner to outside corner of the eye.

5. Did you know a baby’s brain doubles in size by their first birthday? DHA is an Omega-3 fat that is abundant in our brains and retina, and is important for neural, cognitive, and visual development. Ensure your baby gets enough by including enough DHA in your diet during breastfeeding, or by choosing a DHA-enriched baby formula.

Top 5 Causes of a Twitchy Eye

Ever wonder why that pesky eyelid will randomly begin twitching for days to even weeks on end? Although eyelid twitches are fairly common and harmless, it is bothersome and is a sign that something has changed in your body which you should pay attention to. Here are the most frequent causes:

1. STRESS
Eyelid twitches will usually subside with stress relief. Make time for rest and relaxation, and consider reducing stress with exercise or meditation.

2. FATIGUE
Ensure that you are getting adequate amounts of uninterrupted sleep, and that you are taking breaks through out the day away from your phone or computer screen.

3. CAFFEINE
Try to cut back on drinking caffeinated tea or coffee.

4. EYE STRAIN
Consult your optometrist to check if blurry vision or fluctuating focus might be causing your eyelid to twitch.

5. DRY EYE
Make sure you are blinking regularly when looking at screens. Your optometrist can discuss options to help with irritation caused by dry eye

Feeling The Winter Blues

After all the holiday and new year festivities have ended, winter in Canada can sometimes seem to drag on forever. The lack of sunlight during this time of year can lead to fatigue, mood changes, and disruption to our sleep cycles. Sunlight is crucial since it helps our skin produce vitamin D, an essential nutrient for growth, bone health and immune system function. This sunshine vitamin can also help prevent age related macular degeneration, cancers, diabetes, high blood pressure, and thyroid problems. But what do we do when sunny days are far and few between?

Unfortunately, unless fortified, natural foods contain very little vitamin D. Rather, supplements containing vitamin D3 are best for nourishing your body. Studies show that, in the winter, 40% of Canadians do not have enough vitamin D in their blood. Supplements in the form of drops are recommended over pills, since they are easier to consume and are significantly easier to absorb by the body.

So how much is enough? Health Canada recommends 600 IU (international units) per day for ages 1-70, and 800 IU/day for adults over 70. Osteoporosis Canada recommends 400 - 1000 IU/day for ages 19-50, and 800 - 2000 IU/day for adults over 50. One should not exceed 4000 IU/day. To give you an idea of how much to take, our clinic offers a liquid supplement where one single drop gives you all the vitamin D3 you would need in a day!

Test your eye health knowledge with these commonly asked questions!

Does sitting too close to the TV damage your vision?

Sitting closer than necessary may give you a headache, but it will not damage your vision. Parents of children and teens who habitually sit close to the TV should consider having their vision measured to screen for uncorrected refractive errors.

Does reading in the dark weaken your eyesight?

You may experience eye strain from reading in dim light, but it will not weaken your eyesight or harm the eyes. Reading in the dark is counterproductive because the parts of the eye that generate the clearest, most precise visual images require light in order to function.

Will using glasses or contacts weaken my eyesight? Will my eyes will eventually become dependent on them?

Vision correction (whether with glasses or contact lenses) focuses light rays entering the eye in order to create a crisp visual image on the retina. It is true that nearsighted children become more nearsighted up until age 30 or so, but don’t blame the eyewear! The focusing power of the eyes changes throughout life. That is one reason why routine eye exams are so helpful. Use of eyeglasses or contact lenses will not weaken eyesight or cause any focusing problem to worsen.

Can children with crossed eyes be treated?

The medical term for cross-eyed is strabismus (STRUH-BIZ-MUSS). There are several different causes for misalignment of the eyes, and a thorough eye exam is necessary to accurately diagnose the problem and its cause. Depending on the cause of the crookedness, some children with strabismus can be managed with prescription eyeglasses, whereas other kinds of strabismus require surgery. Prompt treatment is essential to protect the deviated eye from losing vision – a condition called amblyopia (lazy eye).

Is there anything you can do to prevent vision loss?

Most cases of vision loss can be treated. Depending on the specific disorder, vision loss can be halted, reversed, or even completely restored. See your doctor if you experience decreased vision, abrupt flashes of light, or the presence of a “curtain” that obscures your eyesight. Sudden, total loss of vision is a medical emergency – get immediate help.

Will using a nightlight in your child’s room contribute to nearsightedness?

Some researchers have suggested that use of nightlights may contribute to nearsightedness (myopia); however, there is not enough evidence to support this claim. Keeping a nightlight on in your baby’s room may actually help stimulate the infant’s visual development and eye coordination skills when they are awake.
