<1mw laser in eye

thenerdal · Jul 18, 2013

i'm a hypochondriac and my sister pointed a laser at my eye. I worried so much so I had to make an account here. I found the laser and took it and looked at it for the specifications.

Wavelength is 630-680
Max Output is: <1mw
It says CLASS II ALASER PRODUCT

I'd say it hit me for about 2 seconds or 3. I'm wearing prescription glasses btw.

Do I have anything to worry about? Will I be fine? I don't want to go to a specialist since I can't afford it but I will if I have to.

Thanks!

aww you will be fine ive been hit in the eye with 15mW laser Class 3B ive only shown temporary damage my vision is fine 1mW is concidered class 2 witch is not conciddered harmfull.

A Class 2 laser is safe because the blink reflex will limit the exposure to no more than 0.25 seconds. It only applies to visible-light lasers (400–700 nm). Class-2 lasers are limited to 1 mW continuous wave, or more if the emission time is less than 0.25 seconds or if the light is not spatially coherent. Intentional suppression of the blink reflex could lead to eye injury. Many laser pointers and measuring instruments are class 2.

Are you sure? Fuck man, I've been having a bad day of anxiety today. :|

yeah here is the definition for a class 2 laser your blink reflex is fast enough to closed your eye before damage can occur there cant be a way your eye did not close your blink reflex will close it in .25 secounds. you have nothing to worry about

Fuck, but what if I didn't blink fast enough?! WHAT IF?! Nah, jk. Thanks. I needed this. I feel a bit better now.

So is there a difference in Class II and Class 2? According to this: Laser safety - Wikipedia, the free encyclopedia

There's a new system that uses Class 2 and an old system that uses Class II.

Are they the same thing? Does wavelength matter? What if I point the laser at something and it reflects back to me? Will it be bad or not?

Thanks!

thats just different ways of typing 2 and II but im happy your feeling better.

if a class 3B laser hit your eye than you might need to worry ive been hit with the reflection of a 100mW red laser and ive shown no sign of eye damage

When the retina is damaged, the brain will eventually cover the damage by interpolating and using image information from the other eye. While you are correct that the OP likely does not have damage, you are not advocating anything even close to proper precautions after an incident happens. You may very well have damage your retina when you assumed you hadn't.

DO NOT continue giving faulty "advice" based on your own flawed idea of laser "safety."

sorry i just giving info from what the definition of a class 2 laser and from my experiences from other lasers im not an expert on advice

If you're going to be deleting posts in an attempt to revise history, I recommend you also delete your terrible "advice" on class IIIb lasers. :tired:

A 1mW laser isn't going to cause damage no matter what you try - assuming it's actually 1mW or less, of course. More light enters your eye just standing outside during the day.

Well shit, I'm gonna trust the label then! Don't want to worry anymore.

im trying to be nice to you by noticing my mistake but im not going to have you continue to say im a bad person from using my personal experience

Trevor · Jul 18, 2013

I don't care if you hate me until the end of time. What I'm trying to point out here is how detrimental your "advice" can be.

You're a laser hobbyist - you are, in a way, an ambassador for good safety practices to the people who land here from Google searches. When you say that you were hit in the eye with a 15mW class IIIb laser and ignored your "temporary" damage, you are encouraging others to do the same.

Most cheap Chinese lasers that are "15mW" usually output much more than that. Often, you have that sort of laser outputting a few tens of milliwatts of green, and many tens of milliwatts of IR. On LPF, I've seen images of a retina hit by a 60mW laser. It was damaged.

Your "experience" of ignoring a hit by a class IIIb laser of unknown power encourages others to ignore theirs. Retinas do not heal.*

Seriously. Don't do it.

* Steroids can help a damaged retina recover to some extent, but the damage will never entirely go away.

To the original poster --- Your blink reflex will have stopped any damage. Anything under 5mW is considered a "Pointer" laser, and doesn't require safety glasses to be operated. That's not saying, however, to shine it in your eye for an hour, as it CAN still cause damage, but in your case, it wouldn't have.

Things · Jul 18, 2013

A true 1mW laser will not damage your eye, at all, even if you stare into it for a week, or through glasses, contacts etc, there is simply not enough power to cause any harm. Looking at a regular lightbulb is more dangerous.

I'm not saying go shine 1mW lasers in your eye, but you have no chance of damage if for some reason you do.
