Abstract
A method for estimating refraction of an eye of an individual using an image capturing device, the method including acquiring eccentric photorefraction images of the eye using the image capturing device when the eye is successively illuminated by a plurality of light sources, analyzing the eccentric photorefraction images by a calculation module in order to determine at least one refraction parameter, the analyzing is carried out by machine learning using at least one neural network configured to determine the at least one refraction parameter from the eccentric photorefraction images, the plurality of light sources in the step of acquiring being positioned at least two different eccentric distances from the optical axis of the image capturing device and/or arranged along at least two different directions transverse to the optical axis of the image capturing device.
