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.

Intraocular lens - An intraocular lens (or IOL) is an implanted lens in the eye, usually replacing the existing crystalline lens because it has been clouded over by a cataract. They usually consist of a plastic lens with plastic side struts called haptics to hold the lens in place within the capsular bag.

Canon FD 35-70 mm AF lens - The Canon FD 35-70mm AF lens of 1981 was Canon's first attempt at adding autofocus capability to their range of single-lens reflex cameras. Canon took their existing, successful Canon FD 35-70mm f/4 lens and added a box above the lens containing a self-contained autofocus mechanism, Canon's SST (Solid State Triangulation) system, as used in the AF35ML compact camera earlier that year.

Aspheric lens - An aspheric lens or asphere is a lens whose surfaces have a profile that is neither a portion of a sphere nor of a circular cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
