Monitor manufacturers don't make a device that straps onto your head. Apparently wide frames are an issue[1]. When I was playing airsoft, I had ESS goggles. ESS also sold prescription lenses[1] designed to slot into the air holes in the goggles, all you had to do was send them your prescription.

Contacts may be very cheap, but even with dailies, I wouldn't want to put in contacts just to game. I prefer glasses in general.
