Sports Style Polarized Clip-on Flip up Clip Sunglasses Lens Driving Glasses Lens UV400

if you have a small head like i do, i wear childrens size glasses, its a tiny bit big, but otherwise good. i use them with my over the glasses sunglasses to make them a bit darker.

These work fine but the clip is too small and it makes them harder to put on than other clip-ons I have had.
