contact lens

n. small plastic or glass lens placed directly on the cornea of the eye on top of the iris to correct a vision problem or for cosmetic purposes

small plastic lenses placed directly on the eyes to correct a vision problem (used instead of eyeglasses)

A contact lens (also known simply as a "contact") is a corrective, cosmetic, or therapeutic lens usually placed on the cornea of the eye. Modern contact lenses were invented by the Czech chemist Otto Wichterle, who also invented the first gel used for their production.Contact lenses usually serve the same corrective purpose as conventional glasses, but are lightweight and virtually invisible — many commercial lenses are tinted a faint blue to make them more visible when immersed in cleaning and storage solutions. Some cosmetic lenses are deliberately colored for altering the appearance of the eye.
