My goggles, are mainly from a company called Glendale. I have both glass and plastic goggles, and I have 7 sets to cover the range I need, which is 808, plus 1064, and 808-1064=532 at the same time, plus argon and yellow dye, and krypton/ruby.
They are certified.
Glendale = Sperian/UVEX/Honeywell... FWIW.

What you are doing is wrong. You are assuming every one here uses a low power continuous wave laser. My definition of low power is up to a watt. So some new grad student in a lab reads your review and uses those UVEX specs with a femtosecond system, where the peak power may be 150 kilowatts per pulse. See the issue? Its called "Slippery Slope" in debating class.
No, it's called extremism vs practicality.
No grad student is going to buy these glasses to protect his eyes from a 150kW laser. The people that these are being recommended to are asking about buying a 50mW-300mW 532nm laser in most cases, or perhaps a 1-2W 445 laser or a 405.
This is LASER POINTER FORUM, not fermi laser labs at Harvard.
You do not test for repetitive hits, you do not test for bleaching that may occur over time.
You did not sweep the wavelength over the range of lasing covered by the possible sources, what if there is a transmission band 5 nanometers away from your laser diode? You cannot assume in this day and age that all diodes with the same part number will be +/- one nanometer in wavelength, in fact, its often a 20 nm spread.
You did not run a spectrophotometer scan of the coatings/plastic to see exactly what wavelength is covered, and you have no OD spec published, based on real data.
I have HONEYWELL's published data on the SCT-Orange, it clearly states what wavelengths are covered.
You tested under one very small set of conditions. Your test is not valid.
You did not express the limits of your tests.
I think the limits are pretty well expressed. Did I certify these glasses? No. I don't claim that I did. Did I test them against likely scenarios for most of the members of this forum, and particularly for the members that I am aiming for with a very limited budget and a very high tolerance to risk. Younger males who want a laser on a limited budget are going to get that laser. They probably won't get $168 OEM goggles, and especially not enough for themselves and friends.
By pointing them towards some goggles that are made by a reputable company in the U.S. with published light transmittance specs, at a great price, this group of users might be willing to go ahead and get laser protection goggles.
You can pretend that everyone on the forum religiously buys, uses and carefully maintains their goggles, but we all know better in the real world.
By attacking what I own, you used a "Ad Hominem" attack to deflect your lack of standards... Not the way to do things in scientific method.
I wanted to know what you owned, not to attack it. But I do make the point that there are plenty of people buying Chinese goggles with no real certification either. Where is your outrage for them?
This is not a computer program Steve, it is the real world, sloppy, messy and full of people who take un-necessary and even illogical risks.
It is kind of like an abstinence-only sex ed plan. It might sound good on paper, but in reality it rarely works. So you need to have a safety net.
If you can afford to spend $150+ for a pair of goggles and then buy several of those to cover various wavelengths and then some more for your friends, then more power to you. But for a teen who is buying a 1w 445 laser to burn things with, these could be an eye-saver. In the real world.
They are $8, buy a pair and tell us what you think of them.
