I normally wear bifocal glasses. When I need a new prescription, I buy a new frame for everyday life and when I am satisfied with the result, I return the old frames to have new lenses fitted to the new prescription BUT with the reading section of the lens made to be 2x magnifiers. The result is light and comfortable and I can watch TV or walk around without changing the glasses. If you use more than 2x magnifiers, you might need to shorten your paintbrush handles!
FAITH HOPE AND LUCK!
I use an Optivsor from Donegan Optical with an attached LED light system. 2.5X magnification, I believe.
