Do you want vari focal for riding? I don’t know the answer to that.
I do, being able to see where you are going and read a map, see what your garmin says, undertake repairs etc. without changing glasses is a revelation.
I uses a specific pair of glasses for riding as i can look over the top of my day to day pair when I’m in my riding position.
Online retailers will need your pupillary distance measurement to line up your lenses. Specsavers should have measured this for your new set.
