How Does Astigmatism Affect Vision?
Normally, the cornea and lens at the front of the eye have an evenly round shape. This helps focus light rays sharply onto the retina so you can see clearly. With astigmatism, light rays do not refract (or bend) properly as they enter the front of the eye. Vision is blurry at near and far because light rays either fall short of the retina or behind it.
