Astigmatism is another highly common vision impairment, and it often occurs along with nearsightedness or farsightedness. Like those two conditions, astigmatism is an issue of the shape of the cornea and the effect that has on the way light is refracted through to the retina.

Astigmatic corneas are oblong, longer in one direction than the other, and this causes light rays to be brought into focus at different times instead of at the same time, causing a blurring of vision.
Astigmatism Correction

You may have astigmatism if a corrective prescription of glasses does not provide the sought-after clarity that was expected. Luckily there are simple and easy ways to correct astigmatism, such as with a new prescription of glasses or contacts, or perhaps even laser surgery.
