Embodiment 1

[0022] Embodiment 1: By weight percentage, the monomer for producing substrate 1 consists of the following components: 7% dibenzyl maleate, 10% polystyrene resin, 45% diallyl terephthalate, containing bromine Ether 38%, add special UV absorbers UV585 and UV485 in proportion to the monomer, the ratio of monomer to absorber UV585 is 100:0.08, and the ratio of monomer to absorber UV485 is 100:0.08, so as to obtain high contrast substrate.

[0023] A monomer preparation process for high-color-contrast resin lenses: take dibenzyl maleate, styrene, diallyl terephthalate and bromoether according to the required weight ratio, mix and stir evenly, and then add dissolved The absorbers UV585 and UV485 are heated, mixed and stirred, and after cooling, the initiator azobisisobutyronitrile is added, stirred and degassed to complete the injection molding, and then put into the oven. Raise from 30°C to 70°C, keep warm for 4-10 hours, rise from 70°C to 120°C within 2-5 hours, keep warm for 2-...

Abstract

The invention discloses a resin lens with high color contrast. The resin lens comprises a substrate; hardening layers are arranged on the inner surface and the outer surface of the substrate, an anti-reflection layer is arranged on the outer side of the hardening layer on the outer surface, an anti-radiation layer is arranged on the outer side of the anti-reflection layer, a waterproof layer is arranged on the outer side of the anti-radiation layer, and an anti-radiation layer and a waterproof layer are arranged on the outer side of the hardening layer on the inner surface. The refractive index of the substrate is improved through configuration of the monomer raw materials, a large amount of harmful ultraviolet rays are filtered, the three-primary-color luminosity transmittance is adjusted, the color saturation is improved, the human eye color resolution is improved, low-frequency radiation and microwave radiation are reflected and absorbed through the anti-radiation film layers on the inner side and the outer side of the substrate, and the visual fatigue of human eyes is reduced.

Description

technical field [0001] The invention belongs to the technical field of spectacle lenses, and in particular relates to a high-color-contrast resin lens. Background technique [0002] The visible light band of the human eye is 380nm-780nm, and its color change is purple, indigo, blue, green, yellow, orange, red, and the order is fixed. When the human eye is under the condition of dim light and light interference, or the human eye has relatively photosensitive cone cell defects (color blindness and color weakness), the human eye will have a certain perception deviation for the color resolution. In view of the occurrence of this situation, this The invention mainly uses the method of color filtering and color separation to adjust the transmittance of the three primary colors, improve the color saturation, and improve the color resolution of the human eye. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to ...
