Designer eyeglasses to try on

I would like to ball out for one year and get myself designer brand prescription eyeglasses like YSL, Prada, Miu Miu, Tom Ford, etc. I see many cute styles on Nordstrom and Lenscrafter website, but they do not have these selection in-store to try it on. I asked the workers at Lenscrafter and I was told I would need to buy them online first then bring it in to get custom prescription. However, I would like to try them on before purchasing. Does anyone know of any stores where I can try on designer eyeglasses? I’ve already been to the optical store in Bellevue mall.
