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
