Appearance 4/10
They look ridiculous like rubbish sunglasses

Optical protection 2/10
They let in a very noticeable dot. Probably about 5-10mW from my 200mW red. These goggles may or may not protect against a reflected hit and most likely won't protect from a direct hit. 15mW might not cause eye damage if you have a fast reflex but that is besides the point if you're wearing goggles

Overall 0/10
These goggles are rubbish. All they are good at is making the dot more comfortable to look at. Even so I sometimes get temporary eye strain if burn for a while whilst wearing the goggles not good at all.

DO NOT BUY

Here is a video to better demonstrate the review
‪O-Like Anti-Red Laser Safety Glasses Test‬‏ - YouTube

The dot through the goggles is actually slightly brighter in real life than on camera!!
 





Yeah I have a pair of these and I agree they do let about 20mw though..I have the 250mw o like red laser.
 
Yup, the one for blue/green is junk too. Don't buy O-Like goggles.
 
Go for the laser2go goggles instead. They´re great.
 
Oh dear :-/ how can I cancel my order.

*edit*

Oh well..Ill see how they work out if they arrive by the time my red laser gets here. Ill just end up buying the dragon laser goggles thursday anyway..doesn't hurt to have "extra" goggles.

This should be in the "reviews" section so all can see. Ask a mod to move it for you.

Did you actually -meausre- that, or is it just a guess?

Its always hard to tell from a video, but to me it looks like the power reduction is in the order of 100 times rather than 10. That'd still give an OD of 2 which is not really sufficient, but a big difference from only OD 1 which would mean the lenses are like those in colored sunglasses.
 
I made some test With a 155mW 660nm laser and the T-REX 590-780nm goggles from O-Like (measured with my LPM what they let through),
and this goggles as just an OD of 1.4 (Aprox), but the worst is that they advertise at OD+5, OD+6 (incredible).

The goggles for blue-green are as bad as the for red laser, I also measured this.
 
But if you measure with an LPM through the goggles...then you have already burned out the goggles protective capacity.

I thought no goggle was designed to have a beam sustained on it? So..what ur reading on the LPM through the goggles..isnt its actual protective factor for normal viewing is it?

No, because we're talking a laser with only 155mW and a beam diameter of 4mm, impossible to burn laser goggles with this power-aperture beam for a moment.

And so you know, a good goggles with EN207/208 SPECIFICATIONS can withstand a direct power hit from a laser for 10 seconds.
 
I actually have a pair of these goggles, and I did a test on my LPM with a 250mW LPC-815 through these goggles (moving the goggles so that they don't burn/melt), and I wasn't getting a reading on my LPM. These are at least OD2.4+ because they aren't letting 250mW through. My dot is very dim, but because our eyes sense light by an inverse square law, 1mW is going to look half the brightness of 4mW instead of 2mW. A small reduction in brightness is a large reduction in power output.

Regarding the blue/green glasses... I have a pair from Rayfoss, which, while it may not be the same, I can probably say they are similar, and mine will knock out 550mW of 445 and 600mW of 405, so these are probably at least OD2.5+.

And just so everyone is aware... OD3 is generally all you need for anything under 1W, even OD2.5 is alright for most high-powered lasers. OD4, besides for ridiculously powerful lasers (like we are talking multi-watt IR bars), is generally unnecessary.

As long as the dot is reduced to below 1mW, you should be fine for burning, and even a temporary direct hit. Assuming you aren't burning from an inch away, that is.

EDIT: And while I can say for certain that these CANNOT maintain 10 seconds of a direct hit in a single spot, who would let that happen to them anyway? These are easily enough protection from chance reflections.

Is this on your DIY LPM? :whistle:
 
Yes, which has been calibrated now and is also sensitive enough to pick up 1mW with a reading. :P
 
I own a pair of the o-like goggles. I don't even trust them for specular reflection let alone a direct hit.
