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).

Abstract: An eyewear, including a first receptacle and a second receptacle; a first lens element received in the first receptacle; and a light sensor configured to detect incident light and provide a sensor signal based on the detected incident light. The eyewear further includes an analysis module. The analysis module is operably coupled to the light sensor to receive the sensor signal from the light sensor, and operably coupled to the variable optical filter structure to provide a control signal to the variable optical filter structure. The analysis module is configured to control the optical state of the variable optical filter structure thereby adjusting an illuminance ratio of light transmitted by the first lens element to light transmitted at a position of the second receptacle. Further provided is a method for adjusting a variable optical filter system for an eyewear, and a method and computer program for controlling the eyewear.
