Lens for correcting color blindness and color amblyopia through narrow-band guided-mode resonance grating and preparation method thereof

Abstract

The invention provides a narrow-band guided-mode resonance grating lens for correcting color blindness and color weakness and a preparation method thereof, wherein the lens comprises a lens substrate, a grating layer and a planar optical waveguide film layer are sequentially arranged on the surface of the lens substrate from top to bottom, and the grating layer comprises a grating layer for correcting red color weakness and a grating layer for correcting green color weakness. According to the lens for correcting color blindness and color weakness through the narrow-band guided-mode resonance grating, overlapped parts in a spectrum seen by red and green color blindness are filtered through a narrow-band guided-mode resonance grating filtering technology, so that spectral components are changed, and the color blindness and the color weakness are corrected. Therefore, the color blindness and the color weakness can improve the color resolution capability, and the color saturation is higher and the scene is clearer and more beautiful when seeing the scene.

Description

technical field [0001] The invention belongs to the technical field of lenses for correcting color blindness and color weakness, and in particular relates to a lens for correcting color blindness and color weakness with a narrow-band guided mode resonance grating and a preparation method thereof. Background technique [0002] The current production process of color blindness and color weakness correction lenses in the international market is to use the color master factor to mix in the injection plastic and then perform mixed co-injection molding to reduce the spectral frequency of the cone cells of red and green color blindness (patients with abnormal trichromatic vision). Response Spectral Overlap to increase the separation between the color channels of color vision and thus enhance the chromaticity / color difference response. [0003] The disadvantages of the current production of color blindness and color weakness correction lenses in the international market are that the...
