We have a high myope who is preferring his glasses he purchased from glassesusa.com last year over the new 1.74 lenses he purchased from us this year. :eek:
I see that glassesusa uses "1.67 index G-vision Ultra Thin Lenses". What in the world is "G-vision"?! I know glassesusa is not using a digital design for those prices.
Anyone have any insight?
