An optical system having a spectral transmission profile having an average transmittance Ta between 380 nm and 780 nm and an average red light transmittance Tr between a first limit L1 and a second limit L2, with Tr&#x3c;2*Ta/3 and L1=600 nm and L2=780 nm, and the optical system being configured to allow selectively retinal exposure of an eye to at least one selected range of wavelengths of light in the visible spectrum of 460 nm to 530 nm.

Optical system for treating chronobiological disorders and/or myopia

A multifunctional device for an ophthalmic lens or ophthalmic lens blank, comprising an electrochromic layered module and an ophthalmic power layered module, both modules being on the same support layer.

The invention relates to the field of management of an active lens and more particularly to a management system comprising an active lens (), a first sensor () arranged to measure data relating to an incident light on the active lens, a control unit () designed for controlling the active lens according to data measured by the first sensor, wherein the management system further comprises a second sensor () arranged to measure data relating to a light transmitted from the incident light through the active lens, the control unit being further designed to adjust, according to said data measured by the second sensor, the control already performed according to said data measured by the first sensor. Thus the management system allows taking into account data relating to the light passing through the active lens as a feedback in order to finely control the active lens.
