Safety Goggles, 5PCS Adjustable Wide-Vision Protective Glasses, Lightweight Fog-Proof Safety Goggles

Can i use the glasses over contact lenses?

It says UV protection, but does it actually have a U-rating?

Are they anti-fog or 'fog proof' like you say? I bought anti-fog glasses that fogged up right away when wearing my mask.

Are these soft/flexible and do they seal to your face
