I went to the eye doctors and I couldn't ask them because my mom was waiting in the car, and I have yet to tell her because It really isn't a bother for me... I never see the spots unless looking for them....
1. A Window :tsk:
2. I honestly don't think so but... I can't be sure...
3. If yes <1 second I quickly jerked away
4. Approx. 7-10ft.
5. 100mw(approx) and focused to infinity
But there was one more "close" call... I had put it in a new host, and I had to hot glue the Module in place (I put little glue and used a low heat gun) and I was inspecting the outside, and In a moment of stupidity I accidentally pressed the button,(I know, I know, bad, very very stupid...) If anything this may have been the moment but, I think It was just a REALLY close call because I wasn't looking at the module it self or the lens just around the outside, but I have been thinking lately That If i had gotten a burn wouldn't it make sense to be in the center of my vision? Not the peripheral? Please Correct Me If I am wrong, but, thank goodness, if they are burn(s)? they never bother me unless I look for them, I hope that maybe I have an incident like Grix on page 1 but if not, I have taken my lumps, so as to speak, and now I am not going to use the laser until I get safety goggles, and I know to buy goggles before I get a new laser, because we all know it's just too tempting to not use the laser...
EDIT: Hey, are those focalprice ones okay If I was to get a reflection to the eye? Probably not direct but still(stupid me...) How about Glenn's goggles?
A standard glass window will reflect about 10% of light at the perpendicular or a little less. So the reflected beam would have been <~ 10mw.
If you were working in the light, then a maximum of about 2 to 4mw of this will have entered your eye (as your pupils would then have been narrower than the beam). If in darkness, then you might have received up to 10mw. These figures are above the recommended 1 mw/blink reflect limit, but that limit has a substantial safety margin built in.
Based on this exposure, I think it very unlikely that you have suffered any permanent damage (or indeed any injury at all).
The other exposure you mention is different and a bit more concerning. A 100 mw exposure at close range would have the potential to cause damage. If the full width of the beam entered your eye and you were looking directly into it (i.e it was in the centre of your field of view) then any damage would be to the central portion of the retina - known as the fovea. This is a bad injury but I think you would know about that since you would be unable to see objects that you focus on. Otherwise the damage would be away from the centre of the retina and would manifest itself as a blind spot in your peripheral vision. This would be more difficult to detect but is less serious.
Notwithstanding all of this, I wouldn't worry too much. But be more careful next time!
