Webmore. If 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. WebThis can be caused by insufficient power in the lens or by the eye being too short. Since the nearsighted eye over converges light rays, the correction for nearsightedness is to …
