A contact lens is a corrective, therapeutic or cosmetic lens that is placed on the eye’s cornea. People wear contact lenses for different reasons, but mainly because they are practical, because they provide a wider field of vision than glasses and because they are more suitable for certain eye disorders that cannot be corrected accurately with glasses. They are produced and marketed in hard and soft forms, and some now have a UV protection surface treatment to reduce damage from UV sun rays. The following article contains information that will help you choose the contact lenses that are right for you.
