Point a laser at fully blind eye?

[Doc]

Unfuckinbelieveable.

The very fact that this thread is here on the internet puts laser ownership another step closer to being fond memories.

If I were making a case to government against laser ownership; reading this thread aloud would be my trump card.

It's threads like these that made Frothy leave. Seriously, do you think shining a super unstable laser pointer into someones eye is going to do ANY good?!!?

You don't pay a shitload of money for eye surgery so a doctor can shine his pointer in your eye ...

It's the influx of children that made some members leave...

I asked a question kids. A QUESTION, there is a difference between asking a question and doing something.

READ THE THREAD before making silly comments. Of course for the small minded asking a question is a crime. There are no dumb questions, only actions. I wanted to know the biological reasons, but some of you didn't read the thread. In other forums that's a banable offense...

I have 300 posts here and am not a ##$# idiot. SO children please do not insult my intelligence. Thank you, and have a nice day.

For the record I won't allow this but I'd like opinions.

In Laser83's defense he did say that he would not do this or even allow it. There is nothing wrong with having this discussion, I'm sure it will educate many members and guests.

That was the point but too many members simply responded to the thread title without reading it...

laser83-

i would have to challenge your reasoning here. whether you have 3 posts, 300 posts or 30,000 posts, that makes absolutley zero difference. whether you have been on this forum for 1 day, 1 year or 24.6 years makes absolutely ZERO difference. what DOES make a difference is the topic and the subject matter of your inquiry. and you left me no alternative (or a few of the others who blasted this post) to indeed question your intelligence. i am sure your a great guy. i am sure you arent an idiot. i am sure youre a relatively cool guy and a responsible fun laserist, but this question or thought or WHATEVER title you want to put on this is makes people question your intellect.

i pose the question to YOU...

why would you bring this topic up for "arguments sake" or "discussion." were you just considering the biological hazards? were you wrtiting a paper on what could happen? was it (or IS it) being considered? you are 100% correct, i didnt read every single post. i read the first few and realized that it was absolutely inappropiate and unsafe. regardless of any technicality of "well, i was just wondering."

we could all just "discuss" making pipe bombs and we can all just "discuss" how to attach them to mailboxes. we can all just "discuss" how to blow crap up....

but the fact of the matter is, it isnt right and it isnt a responsible thing for people in the field to be discussing. you know its dangerous. i know its dangerous. everyone here knows its dangerous. therefore, why is it being discussed??

getting pissed at me for responding to your post or getting pissed at others for responding to your post in a negative way doesnt change the root of the problem.

Considering a doctor in California has had some good results in implanting retinal stimulation chips, I would not do anything just yet.


About 4 years ago I saw a TV special showing 16x16 with 64x64 with the way,implanted in guys with total blindness. It started working in 50% of the cases. Now 16x16 (256 pixels ) was not much, but to those guys it was seeing grandchildren moving for the first time and some navigation without canes. They could scan their head around and build up a picture well enough to walk down hallway.

Others have had better success implanting electrode arrays on the brain.

I bet you'll hear about this working within a decade;

Its interesting stuff, but nothing useful for a person with a remaining (even remotely) functional eye.

If you were born one-eye blind, these is very little chance your brain would even be able to process data from an extra eye added or activated later on. I doubt someone could ever see with it, let alone develop stereoscopic depth perception.

For a person born completely blind, its even more chanceless. They will never develop vision in the true sense, no matter how good the sensors or even a complete replacement eye would be. The brain has never developed the structures to process visiual information, the sensation would be more like feeling an object and reconstructing its shape, but remotely.

And who cares about posts! No one does.

I've been on this forum for MORE than 3 years now, I know how this place rolls (Well I used to anyway ...), and even I am saying this thread is ridiculous.

No, he didnt leave because of the influx of children. Heck, I'm 15 and get along with him fine. It's just that some people need to use common sense, especially when dealing with an item that CAN PUT PEOPLES VISION AT RISK!

There's a good reason why the FDA banned them ...

People really need to start answering their own questions once in a while. One day this forum will go down (It almost did shut down last year), then are you all gonna run around crazy not knowing how to live anymore?

Not here picking on anyone, infact thats the last of my intentions, I am just trying (read: _trying_) to get people to use more common sense.

There's also difference between stupid questions and questions that do actually help a cause.

 

[Benm]

I still think it was a good question, and sensible answers were given here.

In fact, the topic starter more or less looked for reasons to discourage someone else from doing something dangerous to her, and hopefully our answers were convincing enough.

Thanks, Benm. Yes, there was a method behind the madness. I'm sure those reading simply saw: "point laser at eye" and started to have a fit. This wasn't the typical topic, and I expected more mature reactions but that's a dream.

There's also difference between stupid questions and questions that do actually help a cause.

I'll ask whatever question I like. If it's stupid that's just your opinion and therefore does not matter. My reasoning in asking such a question was to get information from an eye doctor and not mere hobbyist who knows little to nothing about the eye. I can tell you it's idiotic to point a laser at a blind eye. That's called common sense, what is annoying is that I'm attacked merely for wanting medical details on why that would be a terrible idea. Someone with some experience as medical professional posted and answered the question; your opinion was not needed.

If you don't like the question I asked, tough. There are people who might have tried this. Did you consider that reading this thread might change their mind? Furthermore, do you think I spent over 2 grand on lasers, and have done my own builds without detailed knowledge of basic safety? 400mW will blind a person without question. Please do not assume I don't know that.

Do not stifle debate or dismiss a question simply because it's common sense.

people will come up with stupid ideas for as long as people walk this earth!!!! but guess what, it is the resonable person who doesn't act on such impulses. . Think of all the people with no laser experience that have the 1-5mw reds, most of them shine them in peoples eyes with out discussion. now lets say if a few of those people get some high powered ones from dx, ledshoppe etc. they will still shine it in someones eye. now lets say some of the few that got the high powered typed in to google "what would happen if...." then they would get directed to this thread. and it might actually prevent a major accident. and i have read all post and don't see any positive responses, a few jokes, but nothing to say do it. discussion is rarely a bad thing. every body wants to attack laser83 for a simple thought. he met a blind girl and he is into lasers, to me it is the most logical question to ask. but like i mentioned earlier, a resonable person can distinguish between right and wrong.

Not doubting your knowledge at all, I myself have spent over $4600 in the last 3 years on lasers, making scanners and pointers/modules. I realize you were trying to get an opinion, but writing "Would it be bad if I shone a laser in her already blind eye" doesn't sound very nice, considering even though it IS blind, it will still burn the eye and cause pain.

""Common sense is what tells us the Earth is flat and the Sun goes around it. ""
Heh whoever make that up needs to check again, last time I checked the earth was a sphere, and the earth went around the sun

Great debate tactic but you aren't a moderator. Ah only 19, where do work? Have you had a job before? I work at an airport within a 1000ft range of planes everyday. Care to lecture me on laser safety...

I think you missed the point of the quote... :undecided:

I tire of assumptions, again and for the last time. I never stated I would point a laser into anyone's eye or allow it. Do I need to repeat that again? Is this forum too immature for questions and debate?

 

[pullbangdead]

I've actually seen a study from an ophthalmologist shining a laser into a patient's eye on purpose. The patient still had perfect vision, but had a condition which required that his eye actually be removed very soon. So the surgery to remove his eye was scheduled for something like a week later, and the doctor got his permission to do this experiment on his eye, since it was being taken out anyway. It was pretty interesting, I'll have to see if I can find it again.

EDIT: Ha, found it immediately, my google-fu is strong. http://archopht.ama-assn.org/cgi/content/full/123/5/629

They used a 3A laser green laser, <5mW, for times from 1 minute to 15 minutes. The person's eye was removed 20 days later due to cancer, that's why they could do the test. They also included their own previous studies doing the same thing with red lasers, pretty interesting stuff.

So yeah, it's not unheard of to shine a laser into a person's eye for science, but I think the OP knew all along that he wasn't going to do it on his own. I thought that point was pretty clear, that it was never a question of if he was going to do it, it was simply a question of "what OTHER reasons do you have for not doing it, besides the reasons I already have for not doing it".

interesting discussion.
My initial reaction when I saw the subject line was negative. After reading the whole thread I see that the original intent was benign.

However - laser83, you might benefit from considering a couple of points:

first, the effect a topic's subject line has; a more carefully worded title may have avoided (to some degree) the controversy.

and as for "I'll ask whatever question I like. - I'm sure you will. And those who are concerned about perceptions of our hobby, or the fact that it isn't just mature adults reading here, will respond as they feel necessary. To believe that you can post any damn thing you want is immature and ignores the reality of the environment we're operating under. You may cite freedom of speech, but someone else may cite contributing to delinquency, etc... you for example may not want to begin a discussion of "how to use a laser to initiate (some destructive act)"... I know that is not your intent at all, but claiming absolute right to post anything you like sets you up for such arguments. Let me emphasize though that I don't think what you originally posted was bad, just a bit ill-considered... it's only when you got into defensive mode...
