Myopia, also known as nearsightedness or shortsightedness, is when objects up close are in focus, but objects in the distance appear blurry. Most people with myopia wear glasses or contacts. Myopia is a very treatable eye condition.
Myopia occurs when the cornea is too steep or the eye is too long. When light rays from distant objects enter the uncorrected eye, they converge in front of the retina so the image is unfocused. Laser eye surgery moves the image back onto the retina and this gives crisp, clear vision.
