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.

Abstract: The present application discloses a dedicated repair tool managing system, which comprises a problem collecting device, a dedicated tool selecting device, and a data switching device. The problem collecting device collects the description of the repair problem that needs to be addressed. The dedicated tool selecting device screening information of the suggested dedicated tools for fixing the repair problem(s) that needs to be addressed from the dedicated tool database based on the description of the repair problem(s) such that a user chooses the dedicated tool desired to be acquired from said suggested dedicated tools and a list of the dedicated tools desired to be acquired is formed. The list of the dedicated tools is submitted to the tool cabinet via the data switching device. The tool cabinet automatically provides the dedicated tools desired to be acquired to the user. The dedicated repair tools are thus well-suited management.
