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.

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.

Astigmatism - In optics, astigmatism is a monochromatic aberration in which an optical system has different focal planes for rays in different planes. Lenses and mirrors which are partly cylindrical show this behaviour already for on-axis rays, parabolic mirrors and uncorrected lens systems only proportional to the squared angle between rays and optical axis.
