DiopticsHaven 1 Rec Clip on Sunglasses Rectangular

They do a fair job of blocking the sun.

This provides great shade and the lenses are polarized for more protection.

The lens size was perfect. I had to return it because it was slightly wider than my frames. It’s difficult to measure the frame width accurately (at least for me). If you’re buying these, be aware that they are really dark. Otherwise, the clip-ons are perfect.

This fits almost perfect on my glasses, although a little heavy work well for polarized lenses. Would recommend.

I recently purchased a pair of Flexon 600 54mm frames. The frames were more oval shaped than rectangular, but the shades fit nicely.

Just make sure you measure your glasses. Not great for plastic frames.

Fits nicely over prescription glasses and is attractive.

Perfect fit for my glasses bought at Costco. I am in and out a great deal with my job and these make the transition easy.
