A method is proposed for estimating spectral radiances of the surrounding scene from a reflected image on the corneal surface. A digital color camera and the human eyeball are used to develop a simple imaging system without any specific device. The corneal image consists of a mixture of specular and diffuse reflections from the cornea and the iris. The desired scene radiances are only recovered from the specular reflection component after removing the diffuse reflection component. Experiments are executed in several different conditions.
