When I wear my contacts, I have several pairs of reading glasses of different strengths handy. I pick them up at the drug store :wink: and they work just fine according to my eye doc :D:D:D
My vision changes slightly when I get more tired towards evening, and the pair I use for reading doesn't seem to work as well as my main pair for sewing.
I too have noticed the need for brighter light with my contacts/reading glasses vs wearing my bifocals.
