Stock reading glasses are obtainable with bifocal lenses where there is a line that differentiates the lower reading lens from the upper clear lens. No-line reading glasses perform the same function accept there is no visible line between the two lens viewing areas. As you move your eyes down from the upper half of the lens, the magnification increases slowly allowing you to see better at different close up distances. Reading glasses with tinted lenses are fashioned so that you can read in bright light. For reading in the sun, many people wear regular sunglasses with contact lenses underneath. You could also don regular sunglasses with stick on magnifiers. The only genuine trouble with stock reading glasses is that they may not operate good for your eyesight.
Bifocal reading glasses are glasses that have clear lenses at the top and reading lenses at the bottom. With bifocal reading glasses, you can look straight through the top portion of the lens and still have reading magnification when you look down through the bottom portion. Half-eye reading glasses are flat on the top of the frame and are designed to sit down low on your nose so that you peer down through the lens when reading. Afterwards, when you look up, you do not see through a lens so objects in the distance are not blurry. Full-eye reading glasses are good when you spend a long time concentrating on material close-up. When you look up from reading, objects in the distance appear blurry.
