Lens Strength at Bessie Humble blog

Lens Strength. The power of reading glasses ranges from +0.75 dioptre to +3.00 dioptres. Diopter strength refers to the optical power of a lens. If you know the power of a lens in diopters, taking the inverse will give you the focal length — the distance where light is focused. These are also the units on your standard vision prescription, and they tell you how much refractive power is present in a lens. Lens strength is expressed as diopters (d), which indicates how much the light is bent. And it is the measurement unit for an optical prescription. A diopter is a unit used to calculate the focusing strength of a pair of glasses or contact lenses. The higher the diopter, the stronger the lens. A reading glasses strength chart helps us match our level of visual acuity with the recommended diopter strength. The higher the number on your prescription, the more powerful your glasses are. Learn how to calculate the focal length and lens strength of a thin or thick lens from the index of refraction and the radii of curvature. Reading glasses strength is measured in units called diopters. The goal is to enhance our reading comfort without overcompensating with lenses that are too. The strength of all reading glasses is measured in dioptre, with units increasing by 0.25 dioptre depending on the power of the lens.
