What is Amblyopia (Lazy Eye)?
Lazy eye, or amblyopia, is a loss of vision in an eye that is not corrected by glasses alone. Crossed eyes, eyes that don’t line up, or one eye that focuses better than the other can cause amblyopia.
What is Myopia (Nearsightedness)?
In myopia, the eyeball is too long for the normal focusing power of the eye. As a result, images of distant objects appear blurred.
What is Hyperopia (Farsightedness)?
In this condition, the eyeball is too short for the normal focusing power of the eye. In children, the lens in the eye accommodates for this error and provides clear vision for distance and usually near viewing, but with considerable effort that often causes fatigue and sometimes crossed eyes (strabismus).
What is Astigmatism?
Astigmatism results primarily from an irregular shape of the front surface of the cornea, the transparent “window” at the front of the eye. Persons with astigmatism typically see vertical lines more clearly than horizontal ones, and sometimes the reverse.
