Question about specific goggles (T Rex)

Sorry if there's a thread that talks about these already, I looked around and didn't find anything.

Anyways, I bought a couple pairs of these goggles: 532nm Green 405nm 445nm 450nm Blue Laser Protection Goggles Safety Glasses | eBay
which I intend to use with a 150 mW 532 nm and 1.7 W 445 nm. Now, the price and lack of information about OD (I purchased them before I really understood that laser goggles varied significantly) gives me some pause about their quality. Is anyone familiar with that particular pair of goggles and able to tell me how effective they are? I tested them with the most powerful laser I currently have (a 5 mW 532 nm) and the dot was visible through them, but very dim. They have the word "T Rex" written on the top corner, so I assume that's their brand, but I've never really heard of it.

Any information would be helpful, even if that is just "you should probably get better goggles" (it only cost me $50 for 3 pairs of those so it wouldn't be a great loss). Thanks!

I have had two pairs of T-rex brand goggles (one for blue, one for red) to test them out.

Both of them had extremely low OD's and let a lot light through, they are probably the worst brand of cheap goggles I have encountered.

Albeit, they were a different style than the ones you have, yours could be different.

The first laser I bought came with the cheap ones in your link. They are worth it just for the case they come with :) I have found them online between $8-14. They worked good for me until I wanted to start burning things up close and personal. I then went with these for my 445...

If you look around at all the China Laser Sites, the ones you have linked are normally the ones they include for free...

I'd have to agree with HitShane - The "Eagle Pair" glasses are a great choice for reasonably priced good glasses. They are also offered in a slipover style, for those who wear glasses.
A good source for these is - Survival Laser USA Home, you would also be buying from a forum member!

BTW - WELCOME :beer:

I have 2 pairs of this ones:

190nm 540nm Safety Glasses Blue Violet Green Laser Ray Eye Protection Goggles | eBay

I tested them with my green and blue laser. The green let 10mW though because of IR and the blue let about 2mW thought (That means it is about OD 3). I can't guarantee that they all will be the same, but i tested both of my pair to be the same. :)

Edit: They actually both has this written on them: ANSI Z87.1. I have no idéa what it means.

that means that they are rated for low energy impact I.E. flying chips of metal when drilling or soldering.
Basically it means they are certified to withstand having a book dropped on them. It has no relation to optical propertied.

Ohh, that's still great. A certification of something is better than no certification of anything :beer:

Yeah but they are worse for there rated job than any pound store goggles because of there low VLT so for that job i wouldn't feel comfortable using them since they severely reduce vision. They are probably somewhere around OD0.5 if you are lucky. Of course never having actually seen them tested I could be wrong but that is just my knowledge and advice.

EDIT: sorry i should read more carefully next time about the OD.
However i still stand by the fact that i wouldn't trust them unless either a large sample had been tested or that particular pair had been tested. My advice was mostly general.

Like i wrote in my other post i have tested them to be about OD 3, or are you talking about something else?

I would say this goggles are safe for <3w blue laser if they all have the same OD. But don't blame me if they're not, as this cheap chinese goggles use to vary a lot.

Should I smoke a pair of those exact ones I have and see how safe they are :p

P.S. I must say something is better than nothing... But, if you think just because you have something then you will be fine, is an under statement... Spend the money to protect your eyes :) I found out when buying a recurve bow, that I am left eye dominate, but right handed. I still choose a right handed bow due to rifle and pistol experience with my right hand. I did notice though that when I close either eye, my left eye is clearer than my right eye. I don't want this base to change so I am very careful with my eyes and any bright light... :cool:

I'm not that familiar with the DragonLaser goggles, but I' m sure someone here is.
I've just looked through the "search" feature located at the top of the page, (lots of info.there),
and I see many positive things from DragonLaser owners.
Just in the short time I've been here, I've seen many people spend $100.00 or $200.00 or more on their 1st laser,
then ask where they can find the cheapest safety glasses.
Not to say that is what you are doing, since you are asking for advice.
Whatever you decide to go with, protect your vision ... you only have one pair of eyes. :yh:

I ended up purchasing a pair of fit-over Eagle Pair goggles: Eagle Pair® 190-540nm Slip Over Laser Safety Goggles Them and my 1.7 W blue laser both arrived today.

The goggles, I noticed, leave a small space sort of around my cheekbones. I was probably about two-three feet away from a CD case that I was burning and I noticed a noticeable amount of blue light coming from the bottom of the periphery of my vision. I thought nothing of it for the time being, but still was probably only exposed for about 15 seconds.

However, now that I've taken the goggles off my eyes are a bit sore and it's a bit harder to focus on things--my peripheral vision seems a little worse. There isn't any sort of a noticeable spot or anything, just sort of a general lack of peripheral vision. Should I be concerned about this? Or will it return to normal? Honestly I'm not sure how much of it is just me being paranoid and noticing things too much. Sorry, I think I worded that wrong. I still have what seems to be full peripheral vision, it just seems to be a bit less clear. But then peripheral vision isn't clear usually--I'm probably overthinking this.

And another edit, vision seems pretty normal now--don't think I did long lasting damage or anything, but still my final question remains:

Should I continue to use these goggles even though the gap underneath seems to let light in in some capacity?

My eyes were sore the first few times I used my 445nm. I no longer have any discomfort though. I would try to keep your head square with whatever your doing so you don't get too much splash entering into your vision through the cracks...
