How to Convert Diopters to Magnification

Diopter indicates the amount of curvature of a lens. The thicker the lens, the bigger the curvature. To find the approximate magnification level of a lens, divide its diopter by 4, and add 1. The equation is: Magnification = Diopter รท 4 + 1 For example: For a 3-diopter lens of a magnifier, its magnification = 3/4 + 1 or 0.75 + 1 = 1.75x. Objects viewed under a 3 diopter lens will appear 1.75X larger than normal. For a 5-diopter lens of a magnifier, it …
