Iām surprised your profile picture has sunglasses after listening to a significant amount of Kruse š
they are class 5 IR blocking glasses that stop CCDs catching my eyes i probably should not wear them all the time outside haha
For welding?
for cameras to not capture images of my face that can me automatically recognised
Ahh, smart
yeah, i've tested it... outside in bright sunshine, a photo of my face all you see when you crank up the brightness is the lenses become mirrors, because they are blocking all light the camera is receiving through from the inside
