I got these on Amazon but I want to get some clear ones. They also came with a test light and a piece of photoreactive paper so you can test that their blue light blocking capability is legit. I used it on my wife’s clear blue light glasses and it worked. https://image.nostr.build/43c7d853f68bab359dd1655cd9b95302ba253e80e838cefeaa9b628137926e3d.jpg
