I can't order from a US supplier without a "valid prescription" -- less than 2 years old. I'm well aware of the value of eye exams. But after 40 years of managing my own eyes, even through some serious problems, I'm confident I can live without spending an extra hundred bucks on an exam right now, just so I can buy more lenses.
I'm looking at visiondirect.co.uk
Any better ideas? I haven't even looked at Canada.
