Default Am I Okay?

haha I'm probably fine but just want to know whats up or if this is all in my head or because I've been on the computer for way too long. So I was bored and took my first diode out of a cd-rw drive, knowing it would be IR i set up my video camera on night vision mode to see it and hooked it up. there was no lense or anything. i connected it up to a power source and saw it shine on the camera confirming it worked. i was sure not to shine or reflect it in my eyes, but right now its like i just looked at the sun and everything kind of has a weird fake cloud look to it. but not noticable really. it just feels weird. what is this? has anyone experienced it? Il most likely be picking up some goggles soon.

Sounds like a possible "flash" burn. This is usually from being exposed to something like a welder's flash. However, exposure to the IR will do it as well. It's like a "sunburn" on the surface of your eyes. You will probably be fine. What you are experiencing is not the symptoms of burning your retina. That doesn't mean you didn't. It just means that the symptoms you are describing are of a surface burn. Lie down. Close your eyes for a long time (like go to sleep). If you still have the symptoms when you awaken, got to the Dr. You may experience more "dry eyes" and/or other symptoms of irritation before you're done.

Don't play with light you can't see without protection.


Whether you can see it or not, the light is reflecting off of the surfaces around you. It may not be specular and so dangerous to your retina, but it is still bright enough to burn your eye.

Peace,
dave

kinda strange, you must've gotten a really good hit for you to be affected this much by an un-collimated diode

I guess... I dont even know how but its been like 3 hours and i can REALLY notice it. my eyes are soar, dry. but it was on for only like 10 seconds facing away from me but i was just screwing around and the current was unregulated so im suprised it didnt kill it, must have been a lot of power going through it. 52x cdrw drive.

I really doubt this is from the laser. It could be if you stared into the thing for a few minutes, or caught a flash close up where the light isn't very spread out. Honestly I think it's all in your head, or unrelated to the laser. I'm not saying the diode couldn't hurt you, but I've done things much more risky with NIR diodes and have never had a problem.

It takes a while for your eyes to get used to darkness, especially if you have been behind a bright TFT for too long as you pointed out yourself. That can also cause your eyes to feel dry and sore, like after a gaming marathon.

You should follow daguin's advise.

IMO if you just saw light from your camera then you should be OK.

Well I just got my first green yesterday, it's a KD &quot;Edwina&quot;. I took it outside last night and was shining it at buildings at very long distances which was fine. From ground level I shone it at the top of a 20 storey building and there must have been some fairly reflective surface up there because the spot seemed very bright. I only looked at it for about a second, but then when I went back home I realised my eyes feel a bit strange, something like what the OP said. I am just amazed that even at that distance the light is still what I consider very dangerous for this to occur.

You should be fine. Some people's eyes need a while to adjust to lasers or other bright lights.

Some people's eyes just get tired of being held open so big and for so long while staring at their new laser's light.
