Routine vision check-ups are important – regardless of age or physical health. During an eye exam,
your eye doctor checks for common eye diseases, assess how your eyes work
together and evaluates your eyes as an indicator of your overall health. 

This refers to nearsightedness, farsightedness and astigmatism. Refractive errors are corrected with eyeglasses, contacts or refractive surgery.

This occurs when the eyes are misaligned or when one eye has a much higher degree of refractive error than the other. In such cases, the brain often will ignore or suppress vision from the turned or blurry eye.

Strabismus is defined as crossed or turned eyes. The examiner will check your eyes’ alignment to be sure that they are working together.

Even if your eyes appear to be properly aligned, it’s possible they do not work together efficiently as a team. Such binocular vision problems can cause problems that can affect near vision tasks.

These problems can range from incompletely developed focusing skills in children to normal age-related declines in focusing ability (presbyopia) among older adults.

Many eye diseases, such as glaucoma and diabetic retinopathy, have no symptoms in their early stages. Your eye doctor will check the health of your eyes inside and out for signs of early problems.
