[Review] Laserlands' Protective Glasses 650nm

NOT VERY SAFE

Alright, I just got in my glasses(goggles) today along with my 200mW 650nm o-like dilda. Perfect Here we go.

First, the product. Link below:
Red 650nm 660nm (600~700nm) Laser Protection Goggles - $13.60 : Laserlands

Pictures:
Sorry for the low quality, I don't have a camera at my dorm so... camera phone it is!





Packaging:
4/5
I believe they came in a soft envelope with bubbles, but that may be wrong. I got a lot of packages today and didn't bother noticing the packaging for this particular item. I was excited to get them out The glasses, however, come in a nice, solid casing as you can see in the picture. I'm a fan of the way laserlands packaged this product and they got to me completely unharmed and as-described.

Price:
4/5
Um, they're Really cheap?

Build Quality:
2/5
What you would expect from a cheap product coming out of china. Not the say that it's bad, they work fine for everything I intend to use them for, but they're plastic. Still, these are similar glasses to what you would get from o-like or anywhere like that, if not the same. Or at least I assume.

Overall:
1/5
As you can see, quite a bit of my 200mW dilda's light got through the glasses without too much effort, so yeah.. these don't actually provide any protection. In fact, the only reason to buy these is that they're cheap and you may like their look Oh, and what a nifty little case!

EDIT:: I lied. The OD rated IS posted on the laserlands site. Refer to the link up top.

WAIT!!!!


Concerning your pics, I DON`T THINK that these goggles are able to protect your eyes from a direct 200mW laser hit!!
I was shocked at watching your last pic shining through the glasses :undecided:

I highly doubt that these goggles are safe!!!


I attached a short vid shining a 200mW dilda through my protection goggles. Do you see the difference??
PS: the big red light is from the cam

It's a lot of red laser got through the glasses. I think this glasses not good enough to be a laser glasses.

I would see how they may protect against yellow lasers. But, it appears that against a lot of red, they don't provide much protection. Would like to see how much green is blocked (or transmitted) through them as well.
Thanks for the excellent review. It is very helpful. I was going to purchase these, but definitely not after seeing your review. :thanks:

Right, as I said, a ton got through xD Hence, I would NOT use these to protect from a dilda. From a 50mW though? Well, I don't have one to test with, but I imagine these work fine

Just to ease any concern, I have a different pair of goggles I'll be using with my dilda xD

If they manage to diminish the brightness of your 200mW 650nm laser's dot against a white wall to the point where you can measure the diameter for divergence calculations, then you have found a use for your goggles.

Other then that, they are a risky proposition and should not be considered as guaranteed protection for any laser power level above 5mW, including direct reflections.

Oh and btw, pointing a 200mW laser directly at the goggles will actually damage the coating of anything other than certified goggles with a high OD rating* for that specific wavelength. So try not to look through the damaged part of your new goggles...


Nothing personal, but...

Non-certified goggles suck.:gun:



*Attachment: From Wikipedia - see Protective Eyewear

Laser goggles
Protective eyewear in the form of spectacles or goggles with appropriately filtering optics can protect the eyes from the reflected or scattered laser light with a hazardous beam power, as well as from direct exposure to a laser beam. Eyewear must be selected for the specific type of laser, to block or attenuate in the appropriate wavelength range. For example, eyewear absorbing 532 nm typically has an orange appearance, transmitting wavelengths larger than 550 nm. Such eyewear would be useless as protection against a laser emitting at 800 nm. Eyewear is rated for optical density (OD), which is the base-10 logarithm of the attenuation factor by which the optical filter reduces beam power. For example, eyewear with OD 3 will reduce the beam power in the specified wavelength range by a factor of 1,000.

I think you assumed a little too much here I'm not using them as my means of protection, but I saw their price on laserlands so I wanted to test them out. This is my review, that's all.

And yes, these were intended to block 650nm specifically. The OD rating is not posted on laserlands though, so there's that... But I wasn't expecting all that much from these. Just a pair to test, I could care less if they're damaged now.

Actually, I bought a pair from focalprice to test as well, but those arrived broken. Oh, and provided similar protection to these. Ew.

And of course, I didn't take it personally

EDIT: Should I just write "CRAP" big and bold at the top of my post so people don't take it to mean something it doesn't? Honestly, I'm happy with my purchase because it ended up costing like $14 and I can think of plenty of stuff I can still use these for that doesn't involve eye protection from lasers. Of course, since they kind of fail at their intended use, I can see why all the comments are coming back negative but really this is just a review to rate the product itself NOT to educate on the importance of safety glasses for lasers. I'd call that a tutorial rather than a review.

Personally, I trust them for lasers <50mW ... these are only meant to take the lasers power down enough as to not destroy your eyes. That means they will NOT provide complete protection, just enough to keep you safe.

Trusting them and using them aren't the same...? Not to mention I don't have a 50mW red that would fall into that category anyway...

Nothing against you traveller, I know you know what you're talking about and have a lot more experience than I did, I just think you may have misread or misinterpreted what I was/am trying to say. <3

BTW - I used this goggles for my vid above.
Kevin is also a great guy to deal with!

Hm, nice link, I've never seen this site before! Great prices if they work well, I may have to buy a pair to check them out... OD 5+ should be more than adequate protection if that's accurate.

You should check them out, I have heard nothing but good things about ZS goggles. Thanks for the review, I was going to order these.

Really? I actually hadn't heard about them before this thread but they have great pricing. I still need an anti-green pair, so maybe I'll get them from there. Thanks

Sure, just look at a few reviews first. That was for green though. I assume most of their goggles are the same great quality, but I would be careful, just because I haven't seen a review on that particular pair yet.

I wouldn't risk it.... here are the same glasses with a < 5mw red laser sight for a 22 caliber / air rifle. I ordered these based on the price as well.....
@DJNY...thanks fot the link

Oh, wow, I would have expected them to be able to block 5mW. I was way off I guess.

So then, please, don't buy these glasses as actual protection. I'd probably just avoid laserlands altogether for glasses...
