Will these goggles work for this laser?

Im buying this.

Laser Enhancement Glasses for Red Lasers, ship from USA - eBay (item 120527148291 end time Feb-12-10 08:01:28 PST)

This is my laser:

New Style red laser 200mW /adjustable [OLNRL200] - $44.99 : O-Like, Quality Products, Great Prices

Will it be good? I think it should absorb the all the light because, on the ebay item it says

632nm to 690 nm

For the laser it says:

Wavelegnth: 650nm (+/- 10nm)

Should I be good? I mean if I wear the goggles and then I point the laser in my eye accidently, with the goggles, since its like 20-30 NM off, and my reaction time is about .5 of a second, should I be good? Would the glasses absorb about 80-90% of the light emitted?

+REP if you help me out!

I'm not 100% sure here but those are the opposite of what you want. Those are for increasing the visibility of cheaper red lasers, not for blocking dangerous levels of light. They used those glasses with laser levels.

Im sure someone will step in here and correct me if im wrong.......

Yes those are the opposite of what you need, they will offer No protection at all. Proper (inexpensive) glasses will be blue or green colored.
o-like Red laser safety glasses There may be cheaper ones out there but the cheaper they are the less likely they are to have been tested by anyone here. Cheap ones may only make you think your protected & you may be less careful. Glasses may seem like alot but what is your vision worth?

yah i was going to say


Enhances, or brightens view of red laser beam right on the discripting was like shit... reply asap so he doesint buy these and get blind!

Make sure what you buy has a OD (optical density) of at least 3 in the red.
The goggles you were looking at enhance the visibility of red light by blocking green and blue, but pass red. You need pass green and blue and BLOCK or ATTENUATE RED.

OD3 will knock 200 mW of red down to .2 mW or less.
OD4 would be better. OD5 or OD6 will make it nearly impossible to see the spot of the laser, but ensure total protection.

Thanks guys! Im buying the o-like glasses! =)

I should have at least mentioned that Certified laser goggles is the only way to be absolutely positive that your protected. All certified laser goggles will have an OD rating but not all goggles that claim an OD rating will really be certified.
Alot of people who are 1st buying goggles are hesitant to pay for OEM ones tho.

On the certification: goggles without rating or certification are a real hazard, who knows what they block or how long they last.
ANSI Z136.1 specifies which OD should be used in what situation by calculating the maximum possible exposure (MPE). Look it up on wikipedia. Goggles rated according to this have their OD's and wavelengths listed.
EN207 certified goggles have ratings like D 532 L5, where the D (or I, R and M) specifies if the laser is CW or pulsed, then the wavelength and then what power/energy density it can withstand for 10 seconds. The L number is chosen so that it is at least the OD the goggles have. But I've seen goggles marked OD 10 @ 1064 that would melt within a second where D 1064 L6 goggles would survive way longer.

Goggles certified according to one of these standards is the real stuff, I've seen sellers claim "CE certified" but that doesn't say a thing. Goggles should be certified independent to known standards.

I'm now in the proces of getting these goggles, but for most users some decent goggles will be good enough, not everybody works at high powers (or is as paranoid as me).

Check out dragonlasers.com goggles, I own a pair of their blu-ray and green blocking goggles and they are perfect. They also sell goggles suitable for red lasers.

have fun
