Diffractive goggle area MUST be used in a show/rave. I'm a big fan of clear lenses, they offer a cleaner viewing experience than round lenses (I'll add photos of both types). These glasses have a very slight cloudy tint like most diffractive glasses, but they are very light and you won't have any vision problems. I wear these for hours at gigs and never feel uncomfortable, highly recommend. As a bonus, order an extra pair and give to someone at the show. The expressions on their faces are absolutely priceless. ;)
