Can 1 watt 445nm blind you?

[enigmahack]

Point taken.

My reiteration towards you was a question of your thought process and my opinion on it with reasons why I disagree. That's all.

Its good man, different views are what makes you look at things in different ways. Always remember to stay calm Its good for outside of LPF where people act like human rather than hiding behind their computers.

 

[enigmahack]

I wasn't ever not calm, and how I am here is exactly what I'm like IRL too lol

But looking back at my post I can definitely see how that could be interpreted differently. I suppose if you heard me say it out loud the way I heard it in my head, it would make sense; sometimes these are the shortfalls in the medium.

 

[Toaster]

Yeah man, Thats what gets me introuble here. I talk out loud with tones which you dont get on here

Cheers dude.

 

[Lonewolf]

The person that follows the bad advice is just as stupid as the one that gives it.

Dude everyone is wound so damn tight around here

Yeah but no matter how hard you try, there will always be dipshits

 

[Bluefan]

Lonewolf, is that somebody pissing in an active toaster? That's gotta be the darwin award of the century, regardless of the point you're trying to make.

Why neg rep me so bad

i would take all the instant blindness stuff with a grain of salt

You come into a forum of very knowledgable people, asking a question and then disregard the answer based off of personal experience technically unrelated to what you're asking. (The only thing in common is that the doctor's tool was a laser)

That's like saying "Well, I saw a marksman shoot an apple off of a friend's head at 100 feet. Because of that, I think guns aren't that dangerous"
If that above statement looks a little logically flawed, now you'd know how we're looking at your comments.

You should really sit and read through ALL of the posts in this thread and learn from what's been said. Also look at all the different threads of people talking about experiences where either they themselves, or someone they know close to them lost complete vision, or partial vision in lasers much less powerful than the one you're asking about.

These are just some very quick examples... Hopefully this will make things clear to you.

Otherwise, you're safer pretending that lasers don't exist and move onto a different hobby because you'll just hurt yourself or worse, someone else.

 

[pseudoephedrine]

The thing is b5s402. When you say the doctor uses a laser to fix your retina, you have to consider the precision of the tool he is using. You have no idea of the exposure he is giving you. Nor do I for that matter but I bet it is focused with precision, it is securely fixed and not allowed to move unintentionally and the time of exposure would be known and dialled in with calibrated accuracy. That really is a far cry from a laser pointer that is not going to hit you in the eye at a known focal length or angle, or a steady unmovable exposure, or a known exposure time, or a calibrated power output level.

Why neg rep me so bad

Because the laser used to fix your retina was a zero to three watt adjustable power blue green laser. The same safety class as the 1 watt blue pointer. As well as because if the doctor flipped the aiming joystick over to your optic nerve on the retina, you would find yourself very, very, blind in that eye.

Laser eye surgery works by accepting small amounts of controlled damage to enable a greater goal. Your retina was repaired by using small coagulations (burns) to fuse it to the tissue behind it. If you were told where to look, you would have been able to see the visual effects of burns you received for a few days after the surgery.

In your case the laser was focused to very tiny spots and the damage was minimal. In the case of the pointer, the spot size would be huge and the damage would be considerable.

You effectively got neg repped because laser users can never afford to have incorrect safety advice distributed to the public. When told how the eye safety issue really works, you presented a argument that was false and persisted when told otherwise.

It is the way it has to be for safety reasons.

Sorry everybody and sorry Steve
I had 2 diodes bust on me in the past week so I'm not thinking very straight

 

[LSRFAQ]

Its the holidays and winter, which makes it a tough time for everyone. Note plus one for having good manors, too.

If i accidently get hit in the eye from 1 watt 445 laser will i be blinded instantly?
what if its 1.5 watt?

or will it blur my eyes or something then next day i can't see? i always wondered this

Pssh don't listen to these ppl. They don't know anything other than rumors. You want to figure it out, what better way than testing it yourself. Let us know how it goes

 

[Coherent Light]

Be careful Hank. We know it's sarcasm, but safety is too important to take lightly. He might just be foolish enough to try it.

Of course of course. Sorry i was just caught in the moment!

If your goggles are appropriate for the power you are using them for then you will be safe assuming the laser doesn't burn through them from prolonged exposure at high power.
Might be best to avoid testing them that far while wearing 'em ^_^

I was testing a pair of O-Like's 405/445/473/532 goggles with 850mW of 445 in front of an LPM to see how much they reduced the power, and I melted a couple spots on a lens by holding them too still in the beam.
(They reduced the power to 6-7mW.)
