WebIf you have myopia or nearsightedness, you would use diverging lenses (concave) to shift the focus of your eye lens backwards so that it can focus on the retina. Just the opposite goes for hypermetropia or farsightedness, in which you would use converging (convex) lens to bring the focus closer. In astigmatism, you would use cylindrical lenses. WebRay Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length. The "three principal rays" which are used for visualizing the image location and size are:
