Buzz,
I have worn glasses since 11 years old for extreme nearsightedness and bifocals for 20 years; so when I had cataract surgery, rather than separate reading glasses and safety glasses, I had lenses installed into my existing frames ground only for reading and to correct a small astigmatism( not required but a little bothersome). I had them made as safety lenses( as before), so if I wear them and carry "clip on" sun glasses( you will have to wear "Shades" outside) my situation is pretty much what I have been used to for the last 62 years, except I can see at distance with out glasses, but can't read my watch.
Mike
