Simply put, the eyeglass lens is a tool you use to focus light appropriately on your retina. For example, a lens that is concave, or curves inward, is used to correct nearsightedness, while a lens that is convex, or curves outward, is used to correct farsightedness.

Nearsightedness causes nearby objects to appear clear, while objects farther away look blurry. Farsightedness is where far away objects appear clear and objects up close appear blurry.

To correct astigmatism, which is caused by distortions in the shape of the cornea, a cylinder shaped lens is frequently used.
