摘要：
The invention concerns a method for estimating refraction of an eye of an individual, comprising the following steps: a) Providing a set of N acquired eccentric photorefraction images of the eye; b) setting values for a set of parameters including at least sphere (110) ; c) Providing a set of N simulated eccentric photorefraction images (120) ; d) Determining an estimator of a difference between the set of N acquired eccentric photorefraction images and the set of N simulated eccentric photorefraction images (130) ; d) Performing an optimization using an optimization algorithm (140) so as to optimize said estimator by adjusting values for the set of parameters and iterating steps c) and d), and deducing an estimation of at least one refraction parameter of the eye.
