I'm a bit skeptical that you could even force yourself to keep looking into the beam even if you wanted to.

Hi,
Short and sweet safety gasses my friend that's all to be said.
Be safe you'll enjoy this great hobby longer without possible accidents .
:))

Seriously, there are only a few possibilities here. One, you are simply a troll. Two, you did NOT stare into the 50 mW beam without attenuating glasses. Three, the laser was not 50 mW but less than 5 mW. Four, you have permanent damage but you either don't notice due to your brain's ability to compensate or you do notice but aren't admitting it. Other than that you are not an alien or super-human so thanks for posting.

Even if you don't see any damage dosen't mean none has happened. Please go see an eye doctor so you'll be sure no damage is done. If some has happened, the earlier you catch it the better!

Being that it was a year ago, it's pointless now.

What do you mean by looked at it? Looking at the beam is always safe, taking a direct hit to the eye is not safe. Looking at the dot up close or while burning stuff isn't safe, the dot can be brighter than the sun and so it can cause damage. I wouldn't be to worried about 50mW though as long as it doesn't reflect off something and hit you in the eye.

To answer your question, <1mW is considered safe however I still wouldn't point one in my eye, <5mW is reasonably safe because your blink reflex is fast enough to prevent damage. Any laser can cause eye damage if you take a direct hit if the power density is high enough (this depends on the area of the beam). Lasers in the visible spectrum will damage your retina while an IR laser that you can't even see can damage your lens or cornea. Any damage is permanent and cumulative, so slight damage that you don't notice will become noticeable with slightly more damage. So it's necessary to be very careful with lasers, someone too careless with lasers over a long period of time could end up with some eye damage before they know it. Also with any class 4 laser (500mW and up) you must avoid any direct contact with the beam, not just your eyes.

Hey Alan, you mentioned up close burning, would you say it's safe to do close burning with a 1W 445nm, provided I use eagle pairs?


Cheers

Its fine if nobody believes, some things just happen.i did manage to buy some glasses, the density is 5, wonder if thats good enough

I directly looked at it, it was 50mw not below, one way to show it was because you can see the beam at night without any type of fog

That isn't one way to show it. Unless you have measured that laser on an LPM, you do not know its power, and I would say it is not 50mW. I have a generic green SD303 pointer that measures 25mW on a good day, and you can see the beam without fog before it even warms up to full power. Your friend has an underspec laser.

Edit: The only other plausible case that I can think of is the laser being quite defocused so that the entire beam was not entering your eye. Which laser does your friend have? Got a link?

That has nothing to do with determining output power, my 30 mW 532 nm Nd:YVO4 DPSSFD green laser has a totally visible beam at night without fog due to Rayleigh scattering. Even a Class 3A/3R <5 mW 532 nm green laser pointer's beam is fully visible on a clear night at that wavelength. As the other person said, only way to know output is through an LPM.
