Cylindrical lens is used to correct astigmatism in the eye, and, in range finders, to produce astigmatism, stretching a point of light into a ey are available in either plano concave or plano convex configurations. Plano concave cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano convex cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
