What does [ADD] in contact lenses mean?

The [ADD] number is required when ordering multifocal/bifocal contact lenses for presbyopia.
The figure determines the amount of correction you need to be able to see clearly at a close distance. The Addition figure is a positive number between +0.50 and +3.00, which some contact lens brands refer to as a high, medium or low.
