comme lunette pour aller dehors c'Est très bien, et pas obliger de cahnger de lunette interieur/Exterieur. le seul petit probleme est l'ajustement pour qu'elle tombe horizontalalement versus mes soucils....

Cómo se observa en la fotografía, no son lentes para leer de aumento progresivo. Son bifocales tradicionales, que además tienen la sección del lente con aumento desalineadas. Los intenté devolver, pero la aplicación me dijo que me reembolsan sin que yo los devuelva. Intenté usarlos un poco más, pero son totalmente incómodos. Aún siendo gratis se irán a la basura. Lógicamente tampoco son fotocrómicos, pero eso ya era demasiado pedir.

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.

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