In the given example, what is the near power value?

• A. +3.00
• B. +1.50
• C. 0.00
• D. +2.00

Answer: (A)

Near power value is the dioptric strength used for viewing close objects. In multifocal or reading prescriptions, it combines the distance correction with the additional near addition to give the total power needed for near tasks. In the example, the near power sums to +3.00 diopters, which is why that option is the best choice. For instance, if you have +1.50 D for distance and a +1.50 D reading addition, the total near power becomes +3.00 D. The other numbers would represent only part of the prescription (either distance alone or a smaller add) and don’t reflect the total power needed for near vision in this scenario.
