Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] Such as Figure 1(a) ~ Figure 1(c) As shown, a kind of color vision correction glasses is composed of a frame 1, two lenses 2 fixed on the frame 1, two temples 3, a multilayer film stack 4 and a multilayer film stack 5, wherein the multilayer film stack 4 is deposited on the front of the two lenses 2 (we define the side away from the eyes as the front), and the multilayer film stack 5 is deposited on the back of the two lenses 2, and the two lenses can be plano lenses, myopia lenses or hyperopia lenses.

[0049] In the color vision correcting glasses of the present invention, the optical characteristics realized by the special film system on the two lenses are obviously different from those of general lenses without the film system. Ordinary ordinary lenses often need to achieve high transmission (above 92%) in the range of 380nm-780nm in the visible ...

Abstract

The invention discloses a color vision correcting lens, color vision correcting equipment and a manufacturing method of the color vision correcting lens. The color vision correcting lens comprises a lens body, wherein an all-dielectric multilayer membrane pack with a selective spectrum transmission cutting-off feature is deposited on the front side of the lens body, a visible-band broadband antireflection multilayer membrane pack is deposited at the back of the lens body, the transmission of the band of 545-555 nanometers is not larger than 1%, the transmission of the band of 435-450 nanometers is 15-25%, and the transmission of the band of 640-655 nanometers is 25-35%. The color vision correcting lens has the advantages that appropriate high-refraction-index and low-refraction-index membrane design is selected, transmission is allowed to be cut off at specific bands while rest visible bands can transmit without obstruction, all environment representation information, brightness information and rich color information are obtained, the color vision abnormality of target groups is weakened greatly, and the quality and satisfaction of learning, work and life of the target groups are increased; the color vision correcting lens is compact in structure, simple to manufacture, low in cost and convenient in large-scale production.

Description

technical field [0001] The invention relates to a living device, in particular to a color vision lens, a color vision correction device and a manufacturing method thereof, which can be applied to fields such as display and life medicine. Background technique [0002] The human eye has the ability to distinguish between black and white and color, because there are rod cells and cone cells on the retina of the human eye. Rod cells can perceive the brightness information of the external environment, while cone cells are mainly used to distinguish various colors, and the cone cells can be divided into three types of cone cells: L, M, and S. Each type of cone cells has a different spectral response to the incident spectrum. The L-type cone cells mainly respond to the long-wave region of the visible spectrum, the S-type cone cells respond to the short-wave region of the visible spectrum, and the M-type cone cells respond to the visible spectrum. Mid-band response of the spectrum....
