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 as figure 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 and processing high molecular polymer, dispersant, solvent and ultraviolet absorber; wherein high molecular polymer is polyamide (PA), commonly known as nylon, or polycarbonate (PC); dispersant and solvent are Disperse Violet 26 (CAS No: 6408-72-6), Solvent Blue 97 (CAS No: 32724-62-2), Solvent Violet 36 (CAS No: 61951-89-1) and Solvent Green (CAS No: 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;

Abstract

The invention relates to a spectacle lens with high color contrast and a preparation method thereof. The lens is composed of a substrate and a strengthening film layer; the substrate is prepared by mixing and processing high molecular polymer, dispersant or solvent and ultraviolet absorber; the lens is formed from the substrate, and then the lens is soaked in liquid silicide, The silicide is coated on the surface of the lens and then dried by heat to form a strengthened film layer. The high color contrast spectacle lens of the present invention can relatively improve the color contrast resolution of the eyes, and effectively filter most of the harmful ultraviolet rays, making it easier to distinguish the scene, thereby effectively reducing the fatigue of the eyes; The effect of "polarizing film layer" can effectively block the scattered light that is harmful to vision, making the viewing scene clearer, so as to achieve the effect of easy visual observation and rich colors.

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...
