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.

WebSee, what u r talking about is called 'sign convention'.....where u assume a Cartesian plane in which the optical centre of the lens acts as the origin and the principal axis as the x-axis.....so any distance on the left side of lens is taken as negative (u= do= distance of the object from the lens) and any distance on the right is taken as positive(v= di= distance of … 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.
