Welcome to Disera Optical in Thornhill, Ontario

Usually it is related to the shape factor of the front surface of the eye called the cornea. Instead of being shaped spherically like a ball bearing or a marble, it is shaped like a football, being more curved in one direction than the other. This brings light to focus at more than 1 point. The root word stigma means point and the prefix A means without a point focus in the eye.

We can help! We offer a number of different eyeglass lenses that can help people of all ages relieve Digital Eye Strain and ease fatigue after extended reading or computer use. There are also lens treatments such as anti-reflective and blue light blocking to protect our eyes and make our eyes more comfortable. We also prescribe many different types of contact lenses to make reading more enjoyable and make it easier to focus from distance to near.

The benefits of daily disposable contact lenses are comfort, convenience and eye health. Daily lenses only stay in your eye for one day, eliminating any buildup of bacteria on the lenses that could cause infections or allergic reactions. So for patients who suffer from allergies, I recommend using dailies over monthlies, even though the cost is a bit more. Dailies also tend to be more comfortable than monthlies, partially because there is no buildup on the lens. They are also more convenient, as you just throw away the lenses after the day, and use a brand new lens the next morning.

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.
