I own what claimed to be a 240mw laser, which is actually 31mw. Anyways, earlier today I was cleaning the lens on the laser when I went to take a look at it. I accidently pressed the button about 6" away from my right eye. It went completely blind for about 10 seconds, and then seemed fine. So I continued to clean it. I realized that I have a tiny spot now where ever I look. When my eyes slide out of focus it disapears. However when I try to look at something in detail there is a gray spot. Could I have damaged my eye permanantly with only a 31mw laser ?
