My doctor only does 1 year prescriptions, my prescription hasn't changed for 15 years. It's important to get your eyes checked, but every year is a bit nuts. I guess we have some federal organization to thank for that.
I'd love to see you guys figure that problem out. Maybe you could figure out how to ship from out of the US or something. Hell, I'd pay more if I didn't have to go to the doctor every year.
Your skepticism is very warranted. I was skeptical at first too, but we've used this method a few times now. It seems to help everyone to see it, then build it.
