safety goggles: 532 and IR

i ordered a 50mw greenie off o-like. i was looking around for safety goggles. found some for 5.99 at focalprice.com. great deal but doesn't protect from the infrared as the laser doesn't have an IR filter. first off, do i need one? and if so where can i find a pair for cheap?
thanks

I don't think cheap goggles exist that block both IR and 532. The only ones I remember seeing that did that were $200.
