Nearsightedness is the most common optical condition in adults worldwide, affecting about 40% of the population. It is estimated that upwards of 90% of the population may eventually become nearsighted due to our increased viewing of phone, tablet and computer screens beginning at a very young age. In the nearsighted eye, light from distant objects focuses in front of the retina, rather than directly on it; so images are blurry.
Correcting nearsightedness by laser treatment involves precisely sculpting the desired correction into the cornea. Glasses and contacts work by adding a concave lens to the eye, whereas laser treatment works by evaporating or subtracting a convex lens shape from the cornea.
