I think most here are too (US), but I found one willing

to listen and try what I wanted (they are my eyes,

afterall...) here in little Ithaca - Dr. Wood is more

imaginative than the average optomitrist, and the glasses

have served me well for years...;-) There is nothing

revolutionary in the idea, and it even avoids "monovision",

a hazard with the usual "bifocal" contact-lens set-up,

and there is almost no learning necessary to use them.

The idea is so obvious, I'm surprised it has not become

standard practice, since there are almost no "downsides",

but lotsa "gains" compared with traditional glasses

solutions to age-related inability to focus...
