A refractive error is when the shape of your eye does not bend light correctly, causing blurred vision. The common refractive disorders are:
Myopia also known as nearsightedness, is when distant objects appear blurry. Myopia is inherited and usually discovered in childhood. As a person ages, myopia can progress, requiring a stronger prescription to correct.
Hyperopia also known as farsightedness, is when close objects appear blurry. Hyperopia is most common in children. It can improve as a person ages.
Astigmatism is an irregular curvature on the cornea (front surface of the eye) which causes a person’s vision to be blurred at all distances.
If you experience blurred vision, difficulty reading or crossing of the eyes, it may mean you have a refractive disorder. Contact your ophthalmologist for a complete eye exam. Refractive disorders are commonly treated with corrective lenses, whether it be eyeglasses or contact lenses. Some refractive disorders may also be corrected by refractive surgery.
