Dirty Dog Sunglasses was founded in 1980 by a collective of leading scientists and designers. From our dedication to innovation a sunglass unsurpassed in style and performance has evolved with the discovery of TR90- A lightweight and virtually unbreakable compound. Dirty Dog's scientific research department were able to provide our design team with a material at the leading edge of sunglass technology. Our designers set about rigorously testing frames composed of TR90 while our scientists experimented with lens technology. Attempting to create the complete sunglass, polyfilter polycarbonate a virtually shatterproof material which blocks 100% of UV rays was the result of the lens experimentation. The lenses were also decentralised for optimum visual performance. A TR90 frame with a polycarbonate lens allowed the Design Team to create contemporary styles without sacrificing strength or perfomance. The team had come up with the most forward thinking high performance sunglass yet, an achievement that is maintained today. Dirty Dog is in demand from successful sports people as a sunglass that can be relied on to perform in extreme conditions. When an athlete is pushing their body to the limit, they can be confident their eyeware is not going to fail them. For that, we can thank the Dirty dog team, who work to produce the best for those who want to perform at their best.
