Thank you for the reply. If I were to get bi-focal glasses for computer
use, the prescription would be something like OD, OS 1.5, add 1.00 &
that would yield a 2.5 diopter lower lens to read with?
Thanks,
Rich

(I am not an OD -- but I think they will agree.)

Greetings,
I am primarily Presbyopic & my prescription I OD & OS +0.5; add 2.00. I
have progressive lenses & my question is about the reading strength of
the lenses. Is it 0.5 + 2.00=2.5 diopters or just 2.00 diopters at the
bottom of the lens.
Thanks.
Rich
