Cylindrical lenses optics
WebCylindrical Lenses. Cyclindrical lenses are lenses having at least one surface that is formed like a portion of a cylinder. Cylindrical lenses are used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line. Visit Website Request a Quote.
