How to Select The Magnification Strength

Wearing the wrong strength of reading glasses results in increased eyestrain and headaches.It’s essential to understand how to select the proper strength for reading glasses without a prescription.

Regular reading glasses are designed to be used for viewing materials approximately 12 inches from your eyes(like reading a book).

Computer Glasses are used for working on the computer approximately 18-20 inches from your eyes.

Please make sure to seclet less power (Usually 60% of the power that you use for reading) for computer glasses.It depends on your reading distance.
