mincl Transition Photochromic Bifocal Reading Glasses for Mens and Womens,Square Clear UV Protection Sunglasses Readers 0~+4

Sirven bien para lo necesario, solo que no se oscurecen tan rápido y no lo suficientemente.

I purchased these bifocal UV blocking transition photochromic "sunglasses" simultaneously with bifocal blue blocking bifocals (LKEYE brand) to better use with my computer (56" monitor). I had previously purchased a pair of PROGRESSIVE blue light blocking reading glasses (LKEYE brand) which proved to be difficult to use with a very , very narrow zone of uncorrected vision (0.0 D) through the top most portion of the lens. To place this in perspective, I'm a 82yo male, post cataract surgery (3 months now), slowly adjusting to new visual parameters. I'm at my computer screen many hours per day and have found the blue light (from the monitor) fatigues and "burns" my eyes. Blue blocking lens (as well as UV blocking sunglasses really help ease the eye strain and discomfort - even with built in monitor protection to lessen the blue light.I strongly disagree with some posted reviews of these Mincl glasses. The bifocal and upper uncorrected (0.0D) lens are quite clear without distortion or peripheral aberration. The transition lens do not darken as much as suggested in the online product photo and do not directly block bright sunlight as much as dedicated polarizing sunglasses, but they definitely "take the edge off" bright sunlight and allow one to read very comfortably in moderately bright sunlight. I believe that a pair of dedicated polarizing sunglasses are needed for comfortable, safe driving or outdoor activities such as playing tennis or sailing. These glasses DO allow one to drive in sunlight and comfortably look down to read instrument gauges and the speedometer - something I could not do well without a bifocal capability. My post surgical implants give me 20/20 vision but make reading the instrument panel very fuzzy.The frames are light, stylish and quite strong. The T90 frame is more flexible and stronger than acetate and somewhat antibacterial as well! Hinges are not spring loaded (unfortunately).The glasses are probably higher priced viv-a-vis many others sold at Amazon (eg. the LKEYE bifocal readers I also purchased are much cheaper but the uncorrected portions of those lens yield slight distortion and do not have photochromic transition protection).Summary: excellent glasses at a fair price with a lovely (almost elegant) eyeglass case and a no scratch lens wipe.

Recently purchases prescription readers and paid $250. These frames were good quality same style as my prescription and the lenses were clear. I like the Photochromic feature which makes them comfortable to wear all day. Only issue is the bifocal portion is very small so its a little harder to find the sweet spot but over all great glasses.

muy decepcionado. para el precio, son de una calidad muy inferior, no son progresivos. y lo peor, el cambio de obscuro a claro es muy deficiente, no como se muestra en la foto. me siento engañado. los devolvi y afortunadamente Amazon me hizo el reembolso de inmediato. eso fue muy bueno

I went through seven pairs of glasses before I got these every other small framed or zero framed set of glasses broke bent and was crap. I don't need a prescriptions I just need reading glasses and I didn't want to have to constantly take glasses on and off. plus I need something that will stay on my head while I'm riding my horse and these are perfect and they look great the transition from Sun to dark is perfect you don't even notice it...... I recommend these 100%
