Which statement accurately describes "add" power?

The statement that accurately describes "add" power is that it enhances magnification for near vision. The term "add" refers to the additional power incorporated into a bifocal or progressive lens to assist with near vision tasks. When a person has presbyopia or similar visual issues, they often require stronger vision correction for close-up activities such as reading or sewing. By adding extra dioptric power to the base prescription, this enhancement allows for better focus and clarity when viewing items that are closer.

In practical terms, when an optician dispenses multifocal lenses, the "add" power effectively provides the necessary increase in lens strength to support near vision, making it a crucial aspect of designing lenses for individuals who need assistance in focusing on nearby objects.
