It works with a few extra steps.

Creating your 3d model is easy and intuitive. You are then redirected to their website to find glasses to try on. Its a shame its not more clear that you have to login to the website, then open the menu, choose "my account", then choose "my virtual try on". The biggest problem is when you first get to the site the sign in screen is broken and impassable. You just need to type glasses.com into the address bar then find the login in the menu system. Its very clunky but once I got it to work I spent an hour "trying on frames" lol! Hope the developers see this and fix the issues by making it a native app experience.
