hi, first post after my introduction.
I hear some people saying they use reading glasses and have reduced their prescription. sorry not totally clued up on all the terminology yet.
I can read a words on my phone, book at 70cm just starting to go out of focus. would i need to look into reading glasses? I might have picked this up wrong.
while I’m hear;
normalised and differentials, what’s the definition please?
there so much to take in…lol
