WebJan 15, 2024 · 1D = 1 m. Thus, a value of − .5 on the ophthalmologist’s prescription can be interpreted to mean that what is being prescribed is a lens having a power of − 0.5 diopters. The minus sign means that the lens is a concave (diverging) lens. Taking the reciprocal yields: f = 1 P = 1 − 0.5D = − 21 D = − 2m. WebMar 5, 2024 · The magnification of a thick lens is easily found. The magnification produced by the first face is, as usual, , and then there is a further magnification of produced by the second face. Thus the overall magnification is , which is this case is +3.356. The image is magnified in size and it is erect.
