Hi Lightspeed, the Aviator Googles (by Jantet) are high end retro googles existing in various colours and models. the Pilot T2 model is specifically designed to wear glasses (the leather gasket is cut off at the spectacle temples level). I'm using this model and it works perfectly with my small round tortoiseshell glasses. The google glasses exist in different colours (transparent, yellow, sun, mirror..) and are relatively easy to change (at least no tools needed :)). Top quality googles worth the high price on the long run !
