Gramps, I'm curious where you bought your glasses from. My mother bought some from Mapusa (the cheapest places I found) and she had vaifocals, reactive, carl zeiss lenses and also Titanium (rimless) frames. It think they cost her 14000 Rs/- (£175) does that compare? The Carl Zeiss lenses were 5000 Rs/- cheaper there than another place for same ones.... (also in Mapusa)...
The one both myslef and my mother used is in Mapusa up the hill towards the Courts, just before the crossroads it's on the left small shop (but you need to take a prescription).
