There is a website that sells over the glasses shades for this purpose, but those are way over priced. Most anything orange stands a good chance of working. You can park an incandescent bulb behind one and look at its spectrum reflected off of a CD or DVD. Look for the blue that looks like the sky on a cloudless day. I'd buy over-glasses safety goggles from a store, then test them at home and return them until you found a pair that works.
