Hey guys i have been using a 50mw green laser for about the past week that i got from ebay. Is it a must to use safety glasses? I mean the beam doesnt bother me unless i shine it close to my eyes. I dont think the laser has a built in infrared filter. What exactly does the infrared filter do for you anyways? I would be welcome to suggestions. I'm also getting a dragon laser 125mw. Will it be necessary to wear safety glasses? Will sunglasses be sufficient until i can buy some online? Thanks sorry for being such a newbie at this
