Don't buy those, I have these myself and they have been tested and are good to at least 2W or so:
HDE Laser Eye Protection Safety Glasses for Green and Blue Lasers with Case (Red) - - Amazon.com
Another cheap one that will work is this:
Uvex S0360X Ultra-spec 2000 Safety Eyewear, Orange Frame, SCT-Orange UV Extreme Anti-Fog Lens - Safety Glasses - Amazon.com they are not even official laser safety glasses but test have shown they work for UV through blue and start to drop off in green. Once you get into the 2W+ range you better be more careful about safety glasses, the cheap ones may not protect you from a direct hit, be careful that a laser won't roll off a table or slip out of your hand, this is when accidents happen. A better medium priced safety glasses would be these:
Eagle Pair® 190-540nm OD6 Slip Over Laser Safety Goggles
