If blurred or distorted vision is making it hard to see clearly at any distance, astigmatism may be the reason—and it is completely treatable.
What Causes Astigmatism?
The majority of people with astigmatism are born with the condition. It’s thought that most people have some degree of astigmatism. It is most likely an inherited condition. Basically, the curve of either your cornea or lens is not an equal curved arc. Instead, the curve is unequal, such as a deeper bulge in the middle (as in a football-shaped cornea, rather than circular normal shape).
This makes light coming into the eye focus at different points, rather than perfectly on the retina at the back of the eye. This creates blurred vision at some or all distances. In addition to being born with it, you can develop astigmatism after having an eye disease, eye injury, or eye surgery. If you’re over 40, your declining up-close vision isn’t due to developing astigmatism. That change would be presbyopia, but that’s a whole different condition.
