Welcome to Disera Optical in Thornhill, Ontario

Astigmatism is usually caused by an irregularly shaped cornea, the front surface of the eye. Instead of being a perfect sphere, like a ball bearing or a marble, it can become a little more like a football, being more curved in one direction than the other. This brings light into focus at more than one point on the retina at the back of the eye, resulting in blurry or distorted vision.

We can help! There are various eyeglass lenses and lens coatings for people of all ages to relieve digital eye strain and ease fatigue after extended reading or computer use. Lens treatments, such as anti-reflective and blue light blocking coatings, protect your eyes and increase comfort. We also prescribe many different types of contact lenses to reduce reading discomfort and make it easier to switch focus from near to far.

The main benefits of daily disposable contact lenses are comfort, convenience and eye health; it's often worthwhile even though they cost a little more. Daily lenses only stay in your eyes for one day, and then get thrown away, eliminating any buildup of bacteria on the lenses that could cause infections or allergic reactions. So for patients who suffer from allergies, dailies are better than monthlies.

The American Optometric Association recommends yearly eye-health examinations. As part of a comprehensive eye exam your optometrist will not only check your glasses prescription for changes, but he/she will also evaluate your eye health. Every patient needs to be regularly monitored for glaucoma and other diseases. For adults, it’s important to monitor for cataracts and macular degeneration. And certain medical conditions, like diabetes, require yearly eye-health exams as well to monitor the potential side-effects they can have on the eyes. For children, visual dysfunction conditions like “lazy eye” and “crossed eyes,” can be missed with school vision screenings alone. A regular complete eye examination is an integral part of routine health care.
