2 years ago I went to Specsavers and got new glasses (expensive, graduated focal length, transitions). A year later the lenses had become abraded, which I put down to my own fault, and replaced them at Specsavers. This time I was *very* careful with them but, 1 year later, the lenses had again become abraded, making my screen hard to see. I've just replaced them again, but not with Specsavers, and have my fingers crossed.
Are there different hardnesses of spectacle lenses -- does someone out there know? I have a friend who had much the same trouble with the same supplier, except his lenses simply crazed. Anyone got any words of wisdom, except caveat saver?
