When a person's near vision becomes less accurate due to presbyopia after age 40, this age-related loss of natural focusing power affects reading and seeing a smartphone or computer clearly and comfortably. Computer screens usually are positioned in the intermediate zone of vision — closer than driving ("distance") vision, but farther away than reading ("near") vision. These computer reading glasses, also called "office lenses" or proximity glasses, allow you to have an optimal vision of what is happening on your screen as well as in your environment. Your correction and a UV-filter are as usual available at no extra cost. Add blue coating, photochromic or polarized filters to customize your eyeglasses.
