WebJun 27, 2024 · Non-prescription reading glasses usually range in power from +0.75 dioptre to +3.00 dioptres (D). Both lenses have the same power, which usually is indicated with a removal sticker on the lenses and/or a permanent marking on the inside of the frame. A dioptre (British spelling) or diopter (American spelling) is a unit of measurement with dimension of reciprocal length, equivalent to one reciprocal metre, 1 dioptre = 1 m . It is normally used to express the optical power of a lens or curved mirror, which is a physical quantity equal to the reciprocal of the focal length, expressed in metres. For example, a 3-dioptre lens brings parallel rays o…
