Near-Sighted A nearsighted eye sees near objects within a certain range very clearly while distance vision appears blurry at all times. An estimated 70 million people in the U.S suffer from this condition. Most often caused when the eyeball is too long for the focusing power of the lens and cornea, nearsightedness creates an overpowered eye which causes images to reach true focus in front of the retina. Correction requires a "minus" lens to "weaken" the eye optically to permit clear distance vision.
Here's how a spherical contact lens corrects nearsightedness. The shape of a nearsighted eye focuses images in front of the retina, producing a blurred distance vision. By reducing the cornea's focusing power, a spherical contact lens creates a single focal point on the retina where vision is sharpest. Being nearsided is not fun get your eyes tested
