If I can see close up very clearly without contacts would need an ADD High or Low on multifocal lenses?

You would likely need an ADD Low on multifocal lenses.

ADD stands for "addition", and it refers to the amount of magnifying power that is added to the lower part of a multifocal lens to correct for presbyopia, the age-related loss of near vision.

If you can see close up very clearly without contacts, then you likely do not need a strong ADD power. A low ADD power would be sufficient to provide you with clear vision at near distances, while still allowing you to see clearly at intermediate and far distances.

Your eye doctor can help you determine the best ADD power for your needs.
