What about thesese ebay glasses?

[mortuus]

So i got theese from ebay today, mostly for my green 40mW, tryied them on and they seem to do the job alright, the dot is very very weak when shining on the wall and i cant see the beam with them on which i can without them even in daylight . But i wonder about OD +5 that good or bad or?

Oh and im getting a 1W blue soon, i would asume these are worthless for such powerful laser, can anyone link to some decent ones that protect good 445nm ?

Link them... It is easy for manufacturers in Ch!na to simply over spec their specs.

Those glasses are hit and miss. Test them before using. For your greenie it is enough but get an eagle pair for a 445nm.
