In presbyopia examples, what is the typical ADD value used?

• A. +1.50
• B. +2.00
• C. +3.00
• D. +2.50

Answer: (B)

Presbyopia requires an extra near-power, called the ADD, added to the distance prescription to help with close tasks. In many educational examples, a common starting addition is +2.00 diopters. This level provides a practical balance for reading or computer work for many patients without overly compromising distance vision. Values like +1.50 may be too mild for typical near work, while +3.00 or +2.50 are used for more advanced presbyopia or higher near demand. Therefore, the typical ADD used in presbyopia examples is +2.00 diopters.
