For me these glasses are great however the frames are very poor construction. I ordered my first pair incorrectly with a low prescription thinking that was the starting point and it would progressively increase. Returned them for a 2nd pair which i wore for a few weeks,<br />That pair was also returned in a bag with the right temple broken off and nose piece pin snapped. Damage occurred with a small drop from breast pocket to hard floor.<br />Amazon promptly shipped 3rd pair which I now have received. The same temple was loose compared to right side at the hinge right out of the box.<br />So these I am trying to keep these protected and not put them in their case or carry them around.<br /><br />Amazon has been great with the return and replacement. I agree with some customers who complain they can;t find the return area on the website . That was tricky for me as well. But is an option in your cart or when your on the product selection page. It may nto appear if you had not ordered the part so I 'm not sure if that's what made it difficult.<br /><br />I would stay away from these glasses if your needing to carry them around with you to many places.<br /> But they are worth a shot if you need bifocals or more.  You may need to return them however i suspect this risk is no worse with any other web order business and Amazon has an easy method for returns.
