Rule 2: A ray of light passing via the optical center of a convex lens appears straight; thus, not it does not bend after the refraction occurs.

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.

WebFeb 4, 2024 · Eyeglasses with convex lenses increase the glass’ refraction and reduces the focal length. The lens, in this case, refracts light before it enters the eye and thus decreases the image distance. By starting the refracting process before the light reaches the eye, the image is able to be brought into focus on the retinal surface.
