I bought a pair of safety goggles from lazerer.com which filter 532/445. I pointed my 445 at the goggles (which were placed on the ground) which is running at about 1.2-1.3W and it began to melt a hole through the goggles. Is this normal? Admittedly they are relatively cheap (paid around $25 for each pair) and I am considering asking for a refund. Where can i get safety goggles which wont melt??
