Review on Enhance Your Vision with Optx 20/20 Stick-On Bifocals, +150 by Dawn Ohara

IMHO. The amount of light entering the eye affects the power needed, so get more power from your sunglasses. They can be cropped to any shape to reduce the height/width profile and limit the field area that these lenses act on. . I love my Mai Jim sunglasses and their ability to wrap and protect from the sun both over the frame and on the sides, but I couldn't read anything in them. I simply cut these lenses to the right height/width and apply them to my sunglasses and other glasses with a drop of water. I wear sunglasses for all activities including swimming in both pool and sea water with a lot of time underwater and so far the lenses have not washed out. However, you must rinse your lenses well for storage, otherwise they will leave a white layer of salt that will affect clarity. has to depend on the amount of light available to the eye (and unfortunately age/age - or if the arms get shorter, hmmm, maybe that's an issue). So I add 1.25 to the clear lenses I wear to work and 1.50 or 1.75 to my sunglasses depending on lighting and activity. I'm lucky enough to be able to see beyond my arm's length, but I need these lenses for close work, I can quickly and conveniently reuse them and stick them onto whatever goggles (or goggles, scuba mask, etc.) I have. I don't like lugging around any bags, wallets, etc. with me. By adapting each pair of glasses to each situation, I can enjoy my activities without having to carry or keep track of multiple pairs of glasses or their associated cases. To make life easier, if you think you'll need a certain amount of power for more than one "glue" scenario, don't buy that much; While they're easy to apply and pop back into the shipping box they came in, simply leaving them on a specific item makes life easier (especially if you trim/cut them for application). A little more info, if you can barely see this area of the magnifying circle on ophthalmologist glasses, they use basically the same rod. I saw this when my husband went to the doctor to fix his new glasses, they just removed the circle and "glued" another lens onto the glass, of course, I'm sure they used something else, not a drop of water, but the same boss. I've tried a couple of times to get glasses in "eyeglass patches" but the field of vision was significantly lost and I felt like going from normal to officially blind - the ability to cut and shape those lenses, allows me to customize applications so I don't check them. "Power" when walking or driving, etc. If you are very careful when trimming, you can get more than one application from a set. For me, I only needed a very thin cut at the very bottom of the sunglass so it wouldn't be visible during normal activities and just enough to consciously look off the bottom edge.
