I needed some distance correction for a few occasions such as watching tv or driving at night. Instead of paying so much for prescription glasses from the eye doctor (even with insurance), these were so easy and quick to try out for the price. The lenses are good. I read reviews of warping and a line for other products. The frames feel pretty cheap and might break. We will see. They look decent though. For the price I ordered an extra pair to put in the car. I tried both the black and clear. I thought the clear was a blue tint but it is very clear and feel like I'm wearing safety goggles. I returned those and got another pair of black. The price and speedy delivery were great.
