Facts to Know from Your Eye Doctor in Durham, NC: About Astigmatism

Symptoms

Oftentimes, astigmatism is accompanied by various other vision problems, nearsightedness or farsightedness among them. What separates them though, is that the former is typically exhibited early in life through symptoms like eye strain, headaches, and the need to constantly squint. This problem can lead children to a difficult time at school.

Causes

Since it could show up in childhood, many experts purport that astigmatism just might be hereditary, where children inherit the refractive problems in their parents’ vision. Another known cause is injury or disease that happened to permanently damage the victim’s cornea function. The disease in this case is called keratoconus, since it makes the cornea thinner and more cone-shaped.
