A member asked:

Res dr i want to know differences between mono focal and focal lences?

A doctor has provided 1 answer

Lenses: I am guessing that you mean mono lenses and bifocal lenses. The former is single vision with one focal point. The bifocal has two focal points, one for near and one for far. You are in the age group where that might be helpful.
