Problems solved by technology

Although reducing glare will reduce eye fatigue, but the visual resolution of colors will also be reduced, thus affecting the ability of visual recognition
Existing sunglasses have the function of protecting the eyes from strong light or ultraviolet rays, but when the sunglasses resist ultraviolet rays and strong light, they reduce the color discrimination of the eyes

Embodiment Construction

[0045] Such asfigure 1 As shown, the high color contrast spectacle lens includes a substrate 1 and a strengthening film layer 2;

[0046] Substrate 1 is prepared by mixing high molecular polymer, dispersant, solvent and ultraviolet absorber; the high molecular polymer is polyamide (PA), commonly known as nylon, or polycarbonate (PC); the dispersant and solvent are Disperse Violet 26 (CAS №: 6408-72-6), Solvent Blue 97 (CAS №: 32724-62-2), Solvent Violet 36 (CAS №: 61951-89-1) and Solvent Green (CAS №: 128 -80-3) mixture, the content of disperse violet 26 is 40%, the content of solvent blue 97 is 30%, the content of solvent violet 36 is 20%, the content of solvent green is 10%; the ultraviolet absorber is UV- 531;

[0047] The ratio of high molecular polymer to the mixture composed of dispersant solvent is 1000:0.06~0.09; the ratio of high molecular polymer to ultraviolet absorber, polyamide (PA) is 100:3~5; polycarbonate (PC ) is 100:0.3~0.5;

[0048] The strengthening film...

Abstract

The invention discloses an eyeglass lens with the high color contrast degree and a manufacturing method. The lens is composed of a base piece and a strengthening film layer, the base piece is formed by mixing and modulating high-molecular polymer, dispersing agents or solvents and ultraviolet light absorbers, the lens is formed by moulding the base piece, then, the lens is soaked in liquid silicide, and therefore the surface of the lens is coated with the silicide, and after heat baking and drying, the strengthening film layer is formed. According to the eyeglass lens with the high color contrast degree, the contrast resolution of the eyes to the colors can be relatively improved, most harmful ultraviolet rays can be effectively filtered out, a user can distinguish sceneries more easily, and therefore eye fatigue can be effectively relieved. Due to the effect of the polarizing coating layer, scattered rays harmful to vision are effectively blocked, and the user can watch the sceneries more clearly so that the effect of facilitating visual observation and enriching the colors can be achieved.

Description

technical field [0001] The invention relates to an optical material and a preparation method thereof, in particular to a spectacle lens and a preparation method thereof, in particular to a spectacle lens with high color contrast and a preparation method thereof. Background technique [0002] The vision of the eyes comes from light, and there are some factors in the light that can damage the eyes, so it is necessary to avoid the damage of these factors to the eyes. [0003] The factors that cause light damage to the eyes are mainly ultraviolet rays and strong light. Ultraviolet light is the most obvious damage to the eyes, so it is best to be able to fully resist; strong light makes the eyes tired and eventually affects vision, so the strong light should be reduced as much as possible. Although reducing glare will reduce eye fatigue, but the visual resolution of colors will also be reduced, thus affecting the ability of visual recognition. Existing sunglasses have the functi...
