WebDec 15, 2024 · A convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point. … 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.

WebIn terms of definitions, the Refractive Index of a lens is the ratio of the speed of light in a vacuum divided by the speed of light in the lens material. In the case of CR-39 plastics, the Refractive Index is 1.49 , meaning that light travels at almost half the speed through it than it does through a vacuum.
