Hi guys, obviously if you stare at a bright visible light source you will get after image. That is, if you stare at the dot of a 445 or 532nm laser on a wall your eyes won't feel well. What happens if you do the same with an IR laser. I don't want to find out but I'm curious; does it cause damage even though there is no after image. Also, what would happen if an IR laser struck an eye. Would you feel it? Does it effect the retina?
I looked through some kids type IR nightvision goggles at the 980nm laser and was surprised to find how bright this laser is. The beam is clearly visible at night through these goggles.
Sometimes I might shine a visible laser at a wall briefly but not stare at it and find I see a slight spot after, but no lasting effects. Will the invisible laser cause more damage?
