A refractive error occurs when the shape of the eye does not bend light correctly, causing blurred vision. The common refractive disorders are:
- Myopia - also known as nearsightedness, myopia is when distant objects appear blurry. The condition is inherited and usually discovered in childhood. As a person ages, myopia can progress, requiring a stronger prescription to correct vision.
- Hyperopia - also known as farsightedness, hyperopia is when close objects appear blurry. Hyperopia is most common in children. It can improve as a person ages.
- Presbyopia - presbyopia is the aging of the lens in the eye, which can make reading more difficult. This usually occurs in people over the age of 40.
- 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.
Refractive errors are commonly treated with corrective eyeglasses or contact lenses. Some patients may benefit from laser refractive surgery procedures, such as LASIK, which are designed to reduce or eliminate the need for eyeglasses or contact lenses.
During the LASIK procedure, a predetermined amount of corneal tissue is removed and the cornea is reshaped to improve the focusing power of the eye and visual acuity.
