Yeah Kenzie SportRx is the call! I've gone straight to them with all my prescription needs and they are super helpful! Better to not waste time, and just got straight to the experts instead. They offer prescription snow goggles, and Over the Glasses (OTG) variations, so there is something to suit everyone. Give one of their opticians a call and they will hook it up! http://www.sportrx.com
They make goggles for glasses called "OTG" goggles, meaning they have a little temple cutout to fit comfortable around the arms of your eyeclasses. Pretty good list of them here: http://www.otg-goggles.com/top-over-the-glasses-ski-goggles-2017/
