It is important to remember that all lenses must be removed periodically to prevent infection and corneal damage,and that proper cleaning is necessary before a lens is reinserted.Two basic types of contact lenses are used today: RGP and soft.Rigid contact lenses are made of firm,durable plastic and are smaller than the cornea.Soft contact lenses are made of a flexible hydrogel plastic and cover the entire cornea and a small rim of the sclera.Although the limit for extended wear lenses is usually 6 nights,certain soft lenses have been approved for continuous wear up to 30 nights.
