Contact Lens Exams, Fittings, & Brands

When light enters your eyes, it passes through your cornea and then through the crystalline lens. Both result in spherical aberration (positive for your cornea and negative for your crystalline lens) that compensate each other, resulting in clear vision.

However, as we age, the properties of the crystalline lens begin to change, resulting in an increase in spherical aberration and glare.

To compensate, aspheric contact lenses negate spherical aberration, providing you with clearer vision.

Astigmatism occurs when the optics of your eye bend light differently along the horizontal and vertical axes, resulting in blurry and distorted vision. Toric contact lenses are designed to correct astigmatism, providing increased lens stability, and clarity. Depending on the brand of toric lens, they will vary in weight or thickness around the edges. This helps to prevent the lens from rotating when you blink.

Multifocal lenses are designed with different prescriptions in the lens to correct distance and near vision. These contact lenses are a good option for patients with presbyopia, a common side effect of aging that causes difficulty focusing on close objects. They also correct myopia, hyperopia, and astigmatism.

If you have ever heard of transition lenses for your glasses, then you probably have a good idea what Transition contact lenses can do for your eyes. Transition contact lenses adapt to different lighting situations, offering superior comfort for those with a sensitivity to light, and reducing glare.

Ask Dr. Chan if Transition contact lenses could benefit you.
