dentist googles are safe??

New certified laser safetye eyewear can't be found much lower than $100, the cheap chinese "CE certified" goggles have a CE mark but are definately not EN207 certified. The EN207 standard requires the 10 second (or 100shots) exposure test, the ANSI standard does not.

Yup this is correct, it's the EN207 standard that requires the 10 second/100 shot exposure standard. ANSI Z136 uses OD with "default failure thresholds" for compliance. It's interesting how the standards evolved from different protection emphases.
 
bionic-badger your answer was very instructive thank you very much.
In my dentist googles appears EN166 has this got something to do with EN207?? cause i believed it was how much mecanical impact could support with out breaking:confused:

The EN166 standard is applicable to all types of personal eye protectors used against various dangers liable to damage the eye or to alter the vision, with the exception of radiation of nuclear origin, X rays, laser beams, infrared rays given out by sources at low temperatures.

The specifications of this standard are not applicable to eye protectors for which separate and complete standards exist, such as anti-laser eye protector, all purpose solar spectacles, etc
 
Thanks for posting that piferal :)

Sounds like these could be as much of a gamble as really cheap goggles. Although companies don't always make things like they should, and could end up making their UV Curing protection glasses stronger than needed. Gamble, gamble, gamble :p

I think those dentist goggles are for UV fluorescent/LED-based lights they use for curing stuff with. The lights aren't even strong enough to burn your skin, so the goggles are just there for low-level eye protection. I wouldn't trust them at all to protect your eyes.

Never said I would trust them :)

Just saying though, have a look around, it's kind of odd how there is an identical curing glasses for almost every style of laser protection glasses. Really wish I could test some of these out strictly for curiosity's sake.

When i finish my exams im going to arrange an appointment with the optics profesor of my university to find out the OD of this glasses, if they have, its now just curiosity. And then i can ask if they have LPM to do some testing:D

Thank you all again for your answers!!

The glasses mentioned conform to EN166 standards. These are the impact resistance standards of CE. They are simple eye protection from flying debris certified. The lenses are polycarbonate which filters UV light by it's normal chemical nature thus usable by dentists who are curing UV activated dental glues and appliances. They offer no optical density to any particular wavelength. What you need are glasses that conform to EN207 or EN208 (latter being alignment filters) to be sure of laser protection.
