Cheap Safety Glasses - TESTED

shadowhawkxx said:
Almost decided on buying a pair of these... (well, an over-glasses version, but they should be the same quality).

Main point holding me back is that post showing the back of the box explicitly stating that the goggles aren't to be used with lasers...

Everyone has to be comfortable with their decision. I believe that is a lawyer-related thing and that they are perfectly fine with the laser powers we are using. That is MY OPINION and others should form their own opinions.

My personal testing is what made it good for me. They are wicked good at stopping 405 and 445 and significant at stopping 532.

For context, I have a 1.8W 445nm from yob, a pair of rayfoss goggles in my possession, and a pair from the OEM GB coming when that ships. These would be for observers other than myself. As I think has been mentioned already in this thread, I wouldn't use these myself all the time, but they seem like they'd work against diffuse scatter from a few feet away, as my friends won't ever be operating the laser themselves.

I have no knowledge of the rayfoss goggles, but I think you are making a good call with the OEM goggles!

what rayfoss goggles? not the ones that are a flack jacket in a world of .50 bmg, the 500mw rated ones listed 445nm at 5od and that's what my cam had on when I took a picture of an 800mw 445nm laser from one foot. Already posted the pic, but the cam is dead Jim, so I thought I would reshare.


The red rayfoss glasses work ok for green but fail at blue completely, though at 445nm spec sheet lists them as OD4. They are in fact labeled as TREX on the nose bridge and on the right ear they have an ANSI code Z87.1 close to the lens and laser use only, stenciled close to the other end.

Not Laser protection goggles but red beam enhancement goggles, for use as standard safety goggles or in other words high impact glasses. Used to help see the laser line from carpentry tools and such. False advertisement from the east, wow never thought that could happen :D

More cheap glasses to test include every blue blocker set of shooting glasses with an orange to amber lens ever made :P I bet they all test about the same as most of the cheap goggles you have tested.

I always concern myself with the safety of others around me (especially the young) when showing off higher powered lasers. I usually make people watch me from 25+ feet away as I have glasses on and they don't. I can't say how many times some stupid moth has flow into the beam 5 feet from my face. That would suck if I had glasses on and someone was standing next to me with a 500mw+ green that didn't have any on.

I previously I didn't have hundreds of dollars to spend to outfit a group of people with laser safety glasses but thankfully do to this post I now have a small collection of these glasses that I can pass around to people that want to enjoy a closer inspection of laser related fun.

Mine are 190nm-598nm Laser Protective Goggles - Rayfoss

I'm pretty sure they aren't the ones you're talking about (in fact, I think I've actually seen the red beam enhancement goggles on that site), but I'll check when I get home in case.


as for the thread... I think i'll go ahead and buy a few pairs. I won't put much faith into their "durability", but they should work against the diffuse scatter I want them for. I don't have an LPM, but I'll test my 1.8W on some of the non-lens material (the over-glasses version is entirely orange plastic), if someone can recommend a safe method.

Looks like i know what glasses to make my friends get if they want to see my laser ;)
 
I'm going to start a new thread for this, but I just got some of the UVEX SCT-BLUE and the short version is DO NOT get them for red laser protection, they offer very little.

I'm a BIG fan of the UVEX SCT-ORANGE for use with 405-532nm but the UVEX blue are virtually useless except to keep in your shop to protect your eyes from metal shavings and such!

Quick results:

Start with a 635nm laser at 690mW...

Add a pair of UVEX SCT-BLUE glasses and you get 238mW

That's virtually no protection at all!

Maybe better with 650-660?

239mW And now we add the UVEX SCT-BLUE goggles

Surprisingly better, but still not really good enough. Not even an o.d. of 1.0

Oh well - I will stick to my DARK BLUE T-REX goggles for reds...

great thread ts +1 and great finds. I have already ordered OEM ARG, but i was looking for some cheap goggles for spectators and such...this is exactly what i was looking for.

thanks for all your hard work, research/detail and tests :beer:

I finally got back from vacation and got my 660nm laser put back together so I could test the SCT-blue glasses. I had very high hopes for these since the SCT orange performs so well! My findings however agree very much with tsteele's;

FAIL.

I don't have an LPM to test them, but I don't need one. The laser is running an LPC-826 at 478mA. It should be over 200mW and right around 660nm. According to the chart, the highest optical density of SCT-blue peaks right at 660nm. so I thought it was worth a try... It blocks SOME, but not even close to enough to be used with that laser. I would guess it is blocking (at most) 50-60%.

They are on their way back to amazon since they are not worth the $9 I paid.

"In the case of SCT-Orange, the tint is designed for use in the dental industry or in other industries where UV lamps are used for curing materials such as paints or inks. As the chart below demonstrates, SCTOrange offers a wide range of spectral protection. It absorbs >99.9% of potentially harmful UVA and UVB radiation. It further provides protection by completely absorbing visible light up to 540nm, which includes violet, blue and certain green wavelengths of light which are emitted by curing lamps. "

Why would they say not for use in laser protection when that's what they are perfect for?
