Anti-reflective coatings. Do I really need these coatings? Are they worth the money?
When you buy lenses you will often be presented with the option to add coatings, specifically anti-reflective or no-glare lenses. With the additional cost you may decide to skimp out but here are some reasons why these coatings make all the difference to your overall visual experience.
Your lens is a highly reflective surface and acts like a mirror reflecting light away from the lens. Therefore instead of receiving 100% of the light rays through the lens, you receive much less resulting in less than crisp vision. The reflection of light rays off the surface of the lens results in glare which is uncomfortable for the eye.
At night especially, in the absence of AR coating, reflections travelling backwards can cause the appearance of “ghost images” which can be hazardous by causing a distraction. Anti Reflective coatings also provide greater comfort and reduce eyestrain when driving at night and also during prolonged computer use.
From an aesthetic standpoint, AR coatings make your eyeglass lens look nearly invisible. Therefore your eyeglasses look more attractive and your appearance is enhanced by allowing your eyes to be seen without the distraction of reflection.
Anti-reflective coatings can be applied to all lens types from single vision to bifocal to progressive lenses. It is also a good idea for sunglasses (the back surface of the lens) as it eliminates glare resulting from sunlight reflecting from the back surface of the tinted lens when the sun is behind you.
The benefits of anti-reflective coatings are a huge factor in ensuring you receive optimal performance from your lenses. From regular AR to premium coatings, ask your eye care professional for your options when making your next eyewear purchase.
WHEN WAS THE LAST TIME YOU HAD AN EYE EXAM?
Your eyes play an important role in your sensory experience so it makes sense to take care of them. Whether you are 9 or 99 years old, regular eye exams with an Optometrist are essential, not only to determine your prescription for eyeglasses but also to assess your general eye health.

During a comprehensive eye exam, your Optometrist will check your eyes for common eye diseases and evaluate your eyes as an indicator of your overall health. Also, a dilated fundus examination for detection of glaucoma, cataracts, macular degeneration, retinal holes and tears, vitreous floaters, diabetic retinopathy and hypertensive retinopathy. Your Optometrist is often the first health care professional to detect chronic systemic diseases such as high blood pressure and diabetes. Updating your eyeglasses with the most recent prescription is important, as even slight changes to your Rx will result in optimal performance of your eyeglasses. Also talk to your Optometrist for suggestions on lens types and coatings that will suit your lifestyle needs.
EYE EXAMS FOR CHILDREN
Eye exams for children also play an important role in ensuring normal vision development and academic achievement of all kids. Vision is closely linked to the learning process. Children with undetected vision problems often will have trouble with their schoolwork. Many times, children will not complain of vision problems simply because they don’t know what “normal” vision looks like.
COVERAGE FOR EYE EXAMS
For British Columbia residents with a BC Care Card, MSP covers kids under 19 years for regular eye exams. MSP will pay a portion of Optometrist fees for seniors over 65 years. For British Columbians between 19 and 65, there is no MSP coverage for eye exams but you may be eligible for coverage through extended medical insurance plans as well as eligibility through disability, income assistance, IA and DVA.
