  • Method And System For Determining Personalized Near Addition Value, Lens With Such Addition
    Publication number: 20170023798
    Abstract: A method for determining personalized near addition value for non-presbyopes, including measuring fusional amplitudes and phoria with at least one addition value, on both eyes of a person at a working distance; finding a mathematical function that predicts the change of a pair of fusional amplitudes and phoria as a function of addition value based on the addition value and the measured fusional amplitudes and phoria; and determining the near addition value according to a suitable relationship between the pair of fusional amplitudes and phoria on the mathematical function.
