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.
