56 CAUSES OF EYE DISORDERS
Nearsightedness (myopia)
Nearsightedness, or myopia, is a very common condition
in which nearby objects are visible but faraway objects are
out of focus and difficult to see.
Farsightedness
Farsightedness, or hyperopia, is a common vision
impairment in which you are able to see things that are far
away, but have trouble seeing things that are up close.
Astigmatism
Astigmatism is a common vision problem that causes
distorted, fuzzy, or blurry vision as a result of an irregular
curve in the eye's lens or cornea.
