Possible burned retina.... Please Read

ilikeadabox said:
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!

Very informative post, thank you! Yes it was a well lit room, and I think it may be possible that I got a side blast, but I'm still curious about the "mirrored" spot, but all together I'm ok, lol.But, my thought still stands, does a laser burnt part of the retina look "burnt" ie. a black "cloud"? Or a blind spot that the brain masks like the natural blind spot?

I am guessing here, but I suspect that it would be more like the non-sensation of objects that are beyond your field of vision. There would simply be no awareness of it. Rather like how something looks behind your head, if you see what I mean!
 
I know what you mean, but my problems are like black clouds almost, except they don't move, maybe they are an effed up kind of floater.... Thank you for your posts:thanks:

You know how people always say parents are to blame for kids acting stupid?

YOU'RE UNDERMINING THE ARGUMENT. Tell your parents. They're only trying to protect you. You can save the stupid stuff until you're 18.
 
I wouldn't give any advice on telling your parents unless I knew them. This one girl I know thought that she was pregnant, everyone told her to tell her parents that they would be understanding but when she told them her dad really beat her up badly. Noone could've guessed that her dad wouldve reacted that way.

Well at least then we can blame the parents... The way you break the news can also have a lot to do with it.

The way I was raised, though, until you turn 18 and move out(well, I'm halfway there...), you live under their rules, so even though I'm 24, if I think I may be in trouble, it's time to tell Mom and Dad.

I suppose it helps to know they aren't going to try to beat me up.(and they couldn't if they tried)
 
the "they couldn't if they tried" also applies for me and trust me that it somehow helps to know it. Not that they ever seriously tried, but well, it allows you to have a bit more "freedom of speech" hehe.

As Invader Zim said, there are exceptions, but we are asuming most parents won't beat their sons for having been injuried lol
 
To be fair, he also said that nobody would have expected the girl's father to react that way, so sometimes, you really can't tell.

But then if we never took chances, the world would be a very boring place, and frankly, not worth living in.

Don't take this the wrong way, but why would you come here asking for help and advice if you're not going to do it?
 
^ yes, this is true, and besides, you are nearsighted, so, just tell your parents you think it's time to re-check your eyes, as you grow your prescription is likely to change and it is really very important to get eyes checked. You can tell your parents you feel the need to be checked, and should the laser topic arise, tell them, "it has nothing to do with lasers it's about seeing for school and all" -Glenn
 
Eye Floaters, Flashes and Seeing Spots in the Eye

This should help... make sure to read at the bottom... that it's most likely just annoying and nothing serious.

Remember... you ARE near sighted :P

EDIT:
also... the VERY VERY VERY BOTTOM...
"If you suddenly see new floaters, visit your eye doctor without delay."
...now wear have I seen that advice before??? hmm...
 
Didn't completely know what floaters were until this. That helped. I've had floaters for a while if that's the case. But it's very rare that I actually see them. They pop up once in a while.

you have the same problems with my friend he got hit with a 50mw (1sec) direct hit. we went to the optometrist.. well the doctor said he just have to avoid to be hit again, gave him a prescription, the spot will go out in 2 or 3 months...
