The net power of the near vision correction is the sum of the distant vision correction and the near vision correction. The distant vision correction is -0.12 diopters, and the near vision correction is +3.20 diopters. Therefore, the net power of the near vision correction is -0.12 + 3.20 = 3.08 diopters.
