A METHOD FOR PERFORMING AN ASTIGMATISM POWER TEST USING A COMPUTING DEVICE HAVING A SCREEN FOR DISPLAYING IMAGES RELATING TO SAID ASTIGMATISM POWER TEST, AS WELL AS A CORRESPONDING COMPUTING DEVICE

摘要

A method for performing an astigmatism power test using a computing having a screen for displaying images relating to the astigmatism power test. The method includes determining an angle of astigmatism, calibrating visual acuity of the user, determining amplitudes required for the astigmatism correction, and determining the needed refraction, as well as a corresponding computer system.
