I would be pleased to have you get these and I really appreciate the lens testing and laser reports you have done for Igor's projects.

Folks, FrancoRob deserves more rep! ;) -Glenn

Collecting the laser pointer colors, I bet a lot of folks did about the order I did:
Red red < 5 mW
Green green<20 mW
Green more green pointers
Red Red burners, Sentorch Daedel several others etc.
Violet Violet first 7 mW then 110... by & by too many to mention
Blue first 473 nm pointer a Laserglow Aquarius -10 later a Viasho
Yellow first "Yellow" CNI GLP 593.5 nm later Vega -5
somewhere in between I got some 635 nm ~ 5 mW pens no big deal,

So the HeNe's, lab type and CO2 and other stuff I didn't include as they are not pointers. Anyway I think that is a fairly common approximate order of collecting laser pointer colors! ;) -Glenn

OK fact, I never stated that you should not wear any protection; I did state that the yellow glasses:angel: were good and sunglasses bad :eg:, while doing my research on a very informative laser site, which happened to be LPF, before I made my statement I found this thread.

Laser Pointer Forums - Discuss Lasers & Laser Pointers> Lasers> Safety & Legal Issues
Welders Goggles and safety

This thread pretty much states what I said about sunglasses and it makes sense if you read the entire thread, that they should not be used for protecting your eyes. Oh and again I did state fact when I said that most safety sunglasses, not the cheap ones you buy at the dollar bill store that don’t give you any warning, warn you not to use them when working with welders or lasers. And another fact, that when you wear sunglasses your eyes do dilate, what percentage, that depends on how dark they are, and that will allow more light to enter the eye, so if you did get a hit from the laser and are not wearing the proper protection you could damage your eyes or go blind. The best advice, and I found this on LPF, is to tell people to wait until they get the correct glasses, that have been tested before they use any laser, your eyes are a terrible thing to waste because you didn’t protect them with the right equipment. NUFF SAID.

@Glenn got my glasses this weekend and they are great, well worth the price.
@Daguin, thanks for testing them.

Tymtravler, it would be nice if you did a bit of research before stating stuff like that as fact.
With BR, sunglasses are WAY better than nothing. Dilation of the pupils is minimal and in my research I have found they cut down on BR by 88% to 97%. My research with other wavelengths suggests that sunglasses here do not block enough (IIRC they blocked between about 60% and 80%) to compensate for pupil dilation. However, they are still great for blu-ray.

I would recommend anyone who owns a powerful blu-ray to purchase these goggles, but until you receive them, to use sunglasses.
Your eyes should be valuable enough to invest in the goggles being sold here, but not protecting them until you have these would be foolish - it would be like someone not wearing a crappy helmet when cycling because their good helmet was coming in the mail soon.

Goggles are superior for many reasons, such as less pupil dilation, better blockage, more reliable dye quality, protection from side shots, ability to wear glasses under and probably a lot more, but sunglasses are in no way worse than nothing.

Sure not using your blu-ray at all until you have the correct goggles would be best, but let's face it.. Most people are going to play around and think "I'll just be careful and nothing will happen."

In these people's case, some temporary protection is obviously better than no protection, and that is what sunglasses provide. We can all agree that they should buy goggles from Glenn, but the real discussion here is whether it is best to wear sunglasses or nothing.

As far as I remember I was the only one who had done actual measurements and pupil surface area calculations and then combined the two, when we originally discussed this issue, which resulted in determining that sunglasses do protect more from 405nm by blocking than they damage by dilating pupils.
Again, these are very old calculations so I do not remember the specific numbers, but I am certain that it was better to wear sunglasses than not, even with the worst case scenario of a beam being exactly the size of your dilated pupil, therefore maximum spill possible for small pupils with the beam still fitting a dilated pupil.

For blocking 532nm and 650nm protection was not sufficient to account for pupil dilation.

I agree completely, use UV blocking sunglasses if nothing worn w/b be done otherwise!
And I so strongly believe that these goggles are well cheap enough and work well enough that, everybody with Blu-ray laser(s) should have them! I stocked up some more goggles, and I'll buy another case if these run low! But please! Use lasers safely! -Glenn
