Statistically, 90% of the population has at least some astigmatism. Astigmatism is when light enters the eye and is scattered instead of becoming focused on one point on the retina. The larger the amount of astigmatism in the eye, the more the light becomes scattered, or the larger the separation of the two focal points in the eye.
To correct astigmatism in the eye, the doctor prescribes a cylendrical prescription to bring the scattered light in the eye back to one focal point. The majority of the population has minor astigmatism, which we call "with the rule astigmatism" and have little difficulty seeing through most quality made eyeglasses.
The real problem happens with astigmatisms that are strong or "against the rule" or with an oblique axis. These conditions cause issues in contact lens fittings as well as with progressive lenses. Many people who have strong astigmatisms have trouble seeing through their eyeglasses. The issue is normally not with the prescription, but with how the eyeglasses are manufactured.
Many times, the equipment that the lenses are blocked in before the edging process distorts the accurate position of where the lens is supposed to be.
This can be a very trying time for the person doing the prescription, the lab tech who is trying to make the glasses, and the person who is trying to get a pair of glasses to see clearly through.
With our experience and dedication to precision and detail, we have found quality eyeglass lenses that help patients with astigmatism to see much better, and we have perfected the manufacturing so that the eyeglass lenses come out accurately.
If you have a unique astigmatism and want to see clearly through your eyeglasses, contact us today and we will be happy to help you to get the clear vision you deserve.
Lenses with an oblique axis or an astigmatism that is against the rule can be tricky when it comes to cutting them properly. Watch a video below that shows how the lens can create the illusion of objects being in places they really are not, which often times causes mistakes when not double checked for accuracy. At Visions of Canada, we carefully assess the accuracy of each lens as it comes out of the blocking machine and correct any errors that are created by the illusions caused by the lens before cutting the lens. Otherwise, many lenses would get cut with their axis pointing in the wrong direction.

We gladly accept referrals from all eye doctors.
