Eye damage?

I just noticed that there is a small, about 3/4" (+/- 1/4" I can't seem to estimate it well) circular spot in my vision where it seems to be a very light gray color. Only when I blink my eyes in rapid succession do I notice and even when I do it still takes a while to see it. It may have not been a laser since I was stupid as a kid. I stared at the setting sun once and sort liked to flash blind myself with 30W incandescents. But recently, I did get a blast from my 110mW blu-ray. I hit myself for a split second, much faster than I could blink, off a window reflection. There are 2 sheets of glass so there were 2 separate dots and I don't know which one hit my eye. One went through a pane went back through it and the other just was a normal glass reflection. I can't remember if both my eyes were hit I don't think they were but I do seem to have the dot in both eyes? Is this eye damage?

I dunno cause now I can't seem to see it at all. It's all in my head I think. I might have seen something bright and it just left that there for a bit and will go away.

Sorry I freaked out sorta.

It may have been temporary damage since you can't see it now... and who knows, maybe you imagined the whole thing! :D...but if it stays like that, then yeah its damage.

generally temporary damage is a white(light) dot or blur while permanent damage is gray or black spots. (is that right?)

I once caught a window reflection from a window, just as you described, from a 200mW blu-ray. I had a dot in that eye for a day or two before it was finally gone.

the short wavelength of blu-ray has no regard for the health of your eyes. It burns up retinas pretty quick.

It seems to be completely gone. I think it was just the lights in my room... and I panicked. ;D

That sucks. I didn't really notice anything with my eyes at the time. Hopefully it did nothing. I thought how stupid that was when it happened. But windows are supposed to reflect 5-10% (is that correct?) so I only got a 6-11mW blast roughly. Less if it was the dot that went through the window twice.

"Temporary" damage still add up right?

yeah temporary damage "adds up". It's best that you try not to let this happen, but you probably already knew that ::)

what you experienced was probably just an "after-image" from having bright light in your eye. just like you would have after a camera flash and/or any other sudden bright light.

Yeah it was most likely just a temporary blindspot. They can be scary, especially if it was caused by a laser, it's kinda your eye's way of saying "Hey watch out where you shine that thing, or you'll end up with this" ;D

The brain is also very able (and willing) to "fill-in-the-blanks" Just like how it fills in the blind spot where the optic nerve enters the eye, it can (and will) fill in any other (new) blind spots after awhile. The only time you will "see" it is if there is a visual anomaly focused directly on the bind spot. You would "see" it then because the brain doesn't have the info to "draw" the anomaly. In that case it would either ignore it (you wouldn't see the anomaly) or it would present the blind spot.

Peace,
dave

How is it you know EVERYTHING? ;D
I have my theories too, but far from what you said which can be verified, so I will just :-X. Check out this artical: http://findarticles.com/p/articles/mi_m1200/is_n17_v139/ai_10724096

I am a 54 year old professor of human communication with a neurotic need to be omniscient (and better than average research skills). ;)

I come to the academy with the focus of a structural psychologist, so anything about the brain fascinates me. :-?

Plus, I read voraciously. [smiley=evil.gif]

The article is cool :cool: Thanks :)

I have had some low powered reflections of my lasers, i only got a little grey spot in my eye when i would burn with my dilda. Usually the damage will be fixed, but you deffidently dont want it to hit the same spot again. Just get some goggles, it will make you feel safer when your using your laser(s)

You should consider going to your optometrist and getting a retinal photograph and a visual fields test :) this would be the only real way to tell if you indeed did cause a bit of damage and now have a positive scotoma which your brain is "filling in"

Those small gray dots you see is just vessels you see inside your eye. You can actually see them.
I see them all the time and they fall down and move around inside your eye.
I asked an eye doctor a time ago.

There are a lot of very smart people here but not one ophthalmologist. If you are indeed concerned about your vision, get yourself to an MD and find out for sure what's wrong (or not.)
