Abstract

Disclosed is a binocular optoelectronic device wearable by a user for measuring a light sensitivity threshold of the user, including: a diffuser configured to face eyes of the user; at least one light source for emitting light toward the diffuser. The diffuser includes predetermined parameters allowing to provide a quasi-homogeneous light diffusion to at least one eye of the user from light emitted by the at least one light source.
