Filtering device of the application that adhere to the spectrum photobiological human

摘要

The device comprises a transparent substrate and mounting means for positioning the said substrate in such a way that it intercepts ambient light and transmits it to at least one of the eyes of a user. It includes means for controlling the light transmission, such that the substrate: - efficiently transmits light whose wavelength lies within the range of the human photobiological spectrum, which range corresponds approximately to the curve of the light-absorption factor of human rhodopsin and - reflects and/or absorbs light whose wavelength is outside this range.
