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.

WebIntroduction: Optics is a field in which light is studied, and the images that form through lenses using the light. Lenses can be used to refract light and create an image. The properties of the thin lens that characterizes it is the focal length (f) and the focal points. The magnitude of f is the distance between the focal point and the center of the lens.

WebA thin lens is one whose thickness is small compared to the other characteristic distances (e.g., its focal length). The surfaces of the lens can be either convex or concave, or one surface could be planar. Because of the refractive properties of its surfaces, the lens will either converge or diverge rays that pass through it.
