These are nice, clear, light weight, but too small for an average adult. And as you can see, much too small to wear over an ordinary pair of glasses. Had to send them back.

I honestly didn't consider myself to have a big head until trying these on and they dug into the sides of my temples... I'd be completely disappointed if these weren't extremely clear lenses. They flex out a little but they aren't as moveable as the description claimed to be.

These are so-so. They have screws on the top holding the arms in place, and one of them kept on loosening. I had to buy small screwdriver to screw it in. Also, I have dark hair, and I think the black line going across looks a bit like an intense uni brow, blending with my own black eyebrows. So not sure if this is too flattering, I don't think uni brows are in right now? However, I do look like I mean business and more determined when wearing them! Grrrr. They are also not very comfortably, hurt the back of my ears after 12 hour shift.

These safety glasses do not have adjustable arms (earpiece) so you cannot comfortably wear them over your regular glasses. I ended up substituting the "NoCry Over-Glasses"

I do not recommend these glasses for hospital staff that works directly with patients for COVID-19 protection. There is no protection on the top part of the frame so when you are working closely on a patient and bending over their body your eyes are exposed. You can adjust the glasses to fit more snug against your face but then your eyelashes hit hit the plastic. I would choose another product that provides protection on all sides of the frame.
