Refractive Error in Children
The school years are a very important time in every child's life. Good vision is a key. Reading, writing, chalkboard work, and using computers are among the visual tasks students perform daily. Refractive errors are the most common cause of vision problems among school-age children. There are 3 common types of refractive errors in children which are myopia, hyperopia and astigmatism.

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.

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).

Astigmatism results primarily from an elongated shape of the front surface of the cornea, which usually causes vision to be blurred or distorted to some degree at all distances. Persons with astigmatism typically see one direction of lines more clearer than the lines 90 degree away from it.

Nearsightedness, farsightedness and astigmatism usually can be corrected with eyeglasses, contact lenses, or refractive surgery.
