Slim rectangle shape polarized clip-on sunglasses.  For the slim rectangle shape to fit your glasses, your glasses need to be a narrower rectangular shape with your frame rim measuring less than 3mm's thick.

Measure one lens of your glasses carefully to the outside rim of your glasses width x height. The slim rectangle shape needs to be nearly the same shape as your glasses and the size clip-on sunglass needs to be the same as the measurement of your glasses or the next size bigger.

All of our sunglasses are rated UV400 protection which is up to 100 Percent protection.

These are generic shape clip-ons and the goal is to get as close to your frame shape/size as possible without them being too snug or too big on your frame.
