Ok, so they wouldn't be called sunglasses. Either way, they have to exist somewhere. I'm pretty sure welder's masks block IR.

A welder's mask is much too dark to play a game with.

There are, however, IR cut-off filters. They're used in photography. See: http://en.wikipedia.org/wiki/Infrared_cut-off_filter

There are also sunglasses that filter out IR only, we wear them in the laser labs in school all the time.

An oxyacetylene welding mask would probably work, since they are less opaque than an arc welding mask.
