(This is the second column in a series about vision correction.)
There are three basic ways to correct faulty vision: eyeglasses, contact lenses or surgery. In this column, we'll cover eyeglasses.
Eyeglasses correct the following vision problems:
Nearsightedness (myopia), which blurs distant objects.
Farsightedness (hyperopia), which blurs near vision.
Astigmatism is caused by an uneven curvature of the eye's surface that produces abnormal focus.
Presbyopia is a natural condition of aging that makes it more difficult to focus on near objects.
