I bought sunglasses in China that claims to have UV400 protection. I'd like to test this as my eyes' health is on the line :)
Is there any way to check the maximum UV amount these glasses can protect me against ?
Thanks, .x

1I don't see how this is a medical question. I doubt if any physician knows how to test sunglasses for UV protection, but optical engineers and physicists probably do. I think you'd have better luck asking this in engineering or physics.– Carey Gregory ♦Commented Jun 15, 2017 at 22:00

1@CareyGregory I'm interested in the answer, so I posted it on the Physics SE: physics.stackexchange.com/questions/369916/…– Amazon Dies In DarknessCommented Nov 20, 2017 at 18:55
