While the OP did request "cheap" goggles, I can't recommend anything other than professional goggles for the best protection. Sure other stuff might work (note the term "might") but for the very best protection across a very wide bandwidth of visible light you want truly professional eye protection.
Here's a link to some very excellent goggles, and at a fair price for the level of protection you get:
Im gunna put a Heads up for everyone, Ray Foss does sell Protective glasses but be warned that they arent very good. It does block the beam of a 1 watt 445 enough to be safe however when focused you can still feel that its a bit bright and the dot remains blue which tells a lot. when you shine the beam at the glasses a blue dot still passes through.. a lot dimmer but passes through none the less....
Im going to recomend the Dragon Laser goggles theyre really nice considering being only 20$ theyll block the beam completely and all youll see is a faint yellow dot.
