Also known as a "bandage lens," this contact lens is designed to protect and aid in the healing of a sick eye. This unique lens is frequently combined with precise medication delivery schedules to heal the eye. (Ref: Contact Lens Council). It's usually a large lens which blankets the cornea, retains its moisture, and protects the surface of the cornea. Since the lens is well-tolerated, it provides an effective and often times pain-relieving cover for the eye.
