Abstract: A method for objectively determining the optimal correction of an optical refraction of a subject, comprising the steps of: a) providing said eye of the subject with successive distinct lens powers and recording the corresponding successive neural signals of the subject while said eye of the subject receives a visual stimulus through each lens power, until the recorded neural signal corresponding to one of the lens power shows a maximum neural activity as compared to all the other recorded neural signals (blocks E2 to E5), b) determining that the optimal correction of the ophthalmic refraction of the subject corresponds to a lens power with which the subject exhibits a neural signal showing a given reduced neural activity as compared to the maximum neural activity obtained in step a) (blocks E6 and E7).
