Blu-Ray Goggles under $5

Oakley makes great eyewear and I'll bet dollars to pesos they make laser protective eyewear for military applications but I see nowhere that the Oakleys you will be testing meet Z136.

Blocking 100% of UVA, UVB, UVC and harmful blue light means what exactly? It means it will block that light at what energy densities? Ah now we are getting somewhere. We don't know what energy densities.

The brand you trust their specs on means nothing. It is what is called an appeal to authority. You are suggesting that because the specs you list are trusted they must somehow work for lasers? There is no need to make that statement unless it is somehow being tied to laser light.

Don't burn a hole in your sunglasses. Call Oakley and ask them if that particular model protects against 100+ mW of 405nm laser light. I already know the answer. They will tell you no.

I'm sorry if I am being a bit of an ass but I keep seeing this coming up over and over. You keep stroking each other about the merits of sunglasses until someone says they work then that statement is used as proof every time someone wants to use sunglasses to protect against laser light. Nobody seems to look at the credentials of the person making the statement they accept it a face value. That is a logical fallacy know as appeal to ignorance. When someone comes along who has been in the business and know the mathematics and optics of protective eyewear those credentials are totally discarded.

I don't care what your financial situation is. If you can afford a laser you should have budgeted the safety equipment also. There are no excuses for doing it right, but I'm sure I'll see a long list after this post.

You are not being an ass at all. As a long time reader I am well aware that there are plenty of kids around here who do not really grasp safety concepts. For the greater good it probably is a good idea to keep these sort of discussions strongly biased towards extreme caution.

I do have a proper pair of laser safety glasses too. Just thought I was see what the Oakleys can do. I did also look even further into their site and they do have a laser specific lens for their mil-spec sunglasses. That is not the lens in the pair I have though. I'm just curious to see what exactly they can block and I figure Oakley should be a decent brand to test. I have no intention of putting them on and pointing the damn laser in my eyes....LOL.... while I'm a new poster here I'm not an idiot either. I've learned a few things here and there over the past 40 years.... and playing with fire is one thing I do know not to do. Even though fire can be lots of fun.

The laser specific lens they do offer gives the following specs.
Optical Density not less than 4.0 - wavelengths of 820nm to 850nm and the wavelength of 1064nm*. Visible light transmittance: 54% suitable for medium to low light conditions

just for the record it should be pointed out that these wavelengths are in the nonvisible infrared spectrum.

Are you questioning Igor's credentials? Of everything I've read on this forum he has the highest credentials than anyone here.
No one is trying to discredit you. We get it. Use at own risk. They have to be certified in order to be 100% effective. You would be a fool to chance your eyes with a pair of sunglasses. No one is debating this. But if you can find something that can reduce the impact down to below 2mW its a better option than having nothing at all. You cant assume everyone is smart enough to buy the proper eyewear, or have enough pairs of the proper eyewear when demonstrating the laser to a group of people.

EDIT:

well said.

You have some brown stuff on your nose Ken. Better whipe it off before it stains.

Agreed, I had ordered goggles before I'd even bought a high powered laser. I don't understand why people are so eager not to buy safely goggles. Is $50 or $70 that much money when it comes to your eyes? I don't understand why this topic keeps popping up. The next thread will be how on how someone ruined their eyesight and they'll have only themselves to blame.  

The worst part is a person can afford Oakleys (cost is $90 or more on average) and yet won't spend money on a set of goggles made specifically for lasers.  

No one is debating this. But if you can find something that can reduce the impact down to below 2mW its a [highlight]better option than having nothing at all[/highlight]. You cant assume everyone is smart enough to buy the proper eyewear, or have enough pairs of the proper eyewear when demonstrating the laser to a group of people.

The best option is not to use a high powered laser without proper eyewear or watch it through a camcorder. Beyond that it's your life, do as you please but don't justify why people don't need goggles as it's silly and puerile.

Let Igor speak for himself you are repeating someone else who isn't here to post his ideas in full. If he has points to make I'm eager to see what he has to post here. My first question would be does Igor use sunglasses or goggles? As a well known builder I'd be surprised if he didn't use goggles.

Have you seen this.... :

I'm not condoning the use of non certified Laser Safety Goggles.... but it is interesting...

I cant tell if they were Oakleys or not.. ;D
