No funciona muy mala calidad

Poor quality PLASTIC (scratched) LENSE that DID NOT focus well!! WASTED my money.

I have been using these adjustable reading glasses because I like the functionality. Unfortunately, the ones I bought previously were very fragile and even with great care, they didn't last a year. In particular, the screws to adjust the focus always came loose and broke easily. But these glasses are well made and much sturdier. I can see them lasting longer. Bonus - while I don't think they are particularly stylish, my wife says they look very practical.

The description convinced me that these glasses were worth a try - and the seller didn't disappoint. The quality is better and the price is better than the card glasses in the store. I was asked to rate them based on qualities such as ""lightweight"", ""comfortable"", ""adjustable focus"", and ""sturdiness"". I gave them 5 stars. Here are my reasons. These glasses are very light, if not feather-light like other glasses I own - but I think this is a good thing, because the comfort of those lighter glasses comes at the expense of quality; they all break or bend too easily. These glasses are made of sturdier materials and may weigh slightly less, but I think this is a huge advantage. As for comfort, I like the smoothness of the plastic pieces that rest on and behind my ears. I've worn other glasses that had a slight bulge at the end of the glasses (probably due to the molding process) that was uncomfortable to wear for long periods of time. These glasses don't have that problem. Especially the adjustable focus design, which is really a great invention that allows me to switch freely in various scenarios. I really like this pair of glasses

My husband uses a 2.0 reader but I use a 4.0, which means we need two pairs of glasses. The adjustable focus of these glasses is a technological innovation that allows us to adjust to different distances and needs, saving us the hassle of multiple pairs of glasses, but with the caveat that you need to slowly twist the knob to adjust. They arrived on time and are perfect. As always, Amazon delivers!
