What is nearsightedness?
Nearsightedness, or myopia, occurs when the eye has too much focusing power. A person can clearly see objects up close, but distant objects are blurry. With myopia the eye is either too long or the cornea is too steep to allow light to focus directly on the retina (the film of the eye). Instead, light focuses in front of the retina causing distant images to appear blurry.
Nearsightedness (also referred to as myopia) is a refractive error that is caused by an elongated eye; the eye is slightly longer than average from front to back. This irregular shape causes light to be focused at a point before the retina, where all images are produced, thereby resulting in blurred distance vision while near objects retain their clarity. Nearsightedness is a lower-order aberration that can be improved with laser vision correction at our surgery center in Western Pennsylvania.
