Really wanted to like these sunglass readers because they are a perfect size for my face and just the right darkness for driving in bright sun but the first pair I bought cracked after a month. I decided to give them a second try and the second pair cracked after two months. Unfortunately not very sturdy. Very disappointingUpdate: I emailed this company to tell them the problem and their customer service rep could not have been nicer. she mailed me two replacement pairs promptly. She wanted to make sure that I was satisfied with the transaction. So far, the second set of glasses have been holding upI had already purchased Bifocal Sunglasses, but the lines were quite protuberant making me dizzy. Instead, I bought these Readers 3.0 Diopter and they work just fine.I have struggled for years trying to read in the sun. I squint or even double up and wear my readers WITH my sunglasses. I wish I'd tried reader sunglasses a long time ago. These are high quality and I highly recommend them.I spent a little more than I usually do for beach reading sunglasses, but the quality of these are apparent. Nicely boxed, with a sturdy case, polishing cloth, and keychain repair tool. They are nice looking and should last, they are not flimsy at all.I originally ordered a pair of bifocal sunglasses, but they made me dizzy. I returned them for these. At first I was hesitant to order them, as they were more expensive than the others. Worth every penny. I love the springy bows, and the full lens readers are what I need. Love these. Stylish and functional.These sunglasses are comfortable and lightweight with really nice lenses. I bought the 1.5's to use for distance - driving, working in the yard etc. I wish they made readers with clear lenses as well (they do make progressives in clear). Super happy with this purchase!Reader sunglasses are a great convenience and on my Purchase list for a planned beach vacation.The package arrived and I was immediately taken with how chic they looked when I tried them on.Reading with this pair of sunglasses made the print clear and not blurry, however, the entire lens is a corrective lens so I am unable to use them as sunglasses. Disappointing.These glasses look great and are very comfortable. Some glasses are too big for me, these are perfect. I actually use them for driving and they make things crystal clear while I also look stylish.
