What are the conditions that affect the way our eyes refract light?
Astigmatism is one of several conditions known as refractive errors, which affect how our eyes refract or bend the light. Other refractive errors include: Myopia (nearsightedness). Hyperopia (farsightedness). Presbyopia (difficulty focusing at near).
Why does my eye get worse over time?
It can also be the result of eyelids putting pressure on the cornea. It can get better or worse over time. Sometimes, astigmatism happens after an eye injury or surgery. Another cause is a condition called keratoconus. In this condition, the cornea becomes thinner and more cone-shaped over time.
