A “cheater” is actually a correction, as it helps you see near. If you wear a “cheater” or reader/reading glasses, you will want that installed in the frames. Think of it this way—when you flip up the telescopes, you want to see near as you normally do. The telescopes enhance your reading correction. By installing your reading correction, there is another benefit—it allows you to sit at a more upright working position, which will significantly reduce your back and neck strain.
If you are nearsighted and normally take your glasses off to see close, you most likely have to hunch over your work. By installing your complete prescription in the frames, you will be able to see without hunching over, relieving your back and neck strain!
