Wangly Polarized Unisex Clip On Flip Up Sunglasses Over Prescription And Reading Glasses Frames Suitable For Driving (Grey & Silver)

I'm not a fan of polarized glasses because of what they do to the readability of other surfaces, but these clip-ons are OK. They certainly fit my glasses well enough, and the mechanism seems reasonably robust. They have their own cases, which allows me to keep one in the car and one in the house. Each case has it's own cleaning cloth.

covers lens' perfectly.
