Contact lens - Contact lenses (also known simply as "contacts") are lens placed on the cornea of the eye usually, but not always for corrective purposes. They serve the purpose of conventional glasses, but are very light and convenient, sitting directly on the eye.

Corrective lens - A corrective lens is a lens worn on or before the eye, used to treat myopia, hypermetropia, astigmatism, and presbyopia. The most common types of corrective lenses are spectacle lenses and contact lenses.

Scleral lens - A scleral lens is a large type of contact lens that rests on the sclera and creates a tear-filled vault over the cornea. Scleral lenses are designed to treat a variety of eye conditions which do not respond to other forms of treatment.

Thin lens - In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the focal length of the lens. If the thickness of the lens is not neglected, it is called a thick lens.
