I placed an order and then another one because it was super simple. I had my prescription before and never found something I liked in store. Searching by size was the way to go. The "Try and On" feature wasn't working accurately with my PD but then I was able to measure the new glasses against my own and that worked better to determine fit. I wish they had more plastic crystal/clear or see through with a tinge of blue/turquoise in some models. Would be nice if website would recommend (or email customers) similar models in size after ordering so customers could see if they want another pair.
