CHECKING THE CORRECTIVE LENSES FOR THE SPHERICAL DIOPTERS HYPOTHESIS AND PREPARING THE APPROACH FOR THE ASPHERICAL DIOPTERS HYPOTHESIS

摘要

This paper is designed to simulate the reception of the corrective lenses, with spherical diopters and prepare the approach of the aspherical ones, for a patient. In the paper, the authors have completed the Lotmar mathematical eye model, for spherical diopters, with a law for variation of the refractive index of the crystalline lens, throughout its body. From there, the necessity to verify in practice the previously proposed approach has resulted. The work also proposes a method for the evaluation of the cornea shape and a method for the determination of the surfaces of the contact lens, in the case of the anterior surface of the eye as a spheroid.
