Embodiment 1

[0014] An ultra-light resin lens, comprising a lens body, the surface of the lens body is provided with a coating structure, and the coating structure is from the inside to the outside in order of wear-resistant film layers that are coated on the lens body by soaking. layer, an ultraviolet absorbing layer based on ultraviolet absorbers and reflectors, an anti-reflection coating layer using a silicon oxide layer, and an antifouling coating layer using a fluoride layer.

[0015] An ultra-light resin lens and a manufacturing method thereof, comprising the following steps: 1) Stirring the resin monomer and its auxiliary materials at 25-30°C for 1-2 hours, filtering, pouring them into a glass mold, and sealing the mold; 2) Put the sealed mold into the oven for heating and curing; 3) Open the cured mold, clean the separated glass mold and prepare for the next production, and trim the separated lens to remove burrs and obtain accurate diameter 4) Clean the lens with 50-60°C plasma wa...

Abstract

The invention discloses an ultra-light resin lens and a manufacturing method thereof. The ultra-light resin lens comprises a lens body; a film coating structure is arranged on the surface of the lens body; and the film coating structure comprises a wear-resisting layer, an ultraviolet absorbing layer, an antireflection film layer and an antifouling film coating layer sequentially from inside to outside. The lens manufacturing method comprises the following steps: 1) the resin monomer and the accessories are stirred, mixed, filtered and cast at a constant temperature; 2) heating and curing are carried out; 3) cleaning and finishing are carried out; 4) ultrasonic cleaning is carried out; 5) annealing processing is carried out; 6) checking is carried out; 7) the antireflection film layer is coated; and 8) a finished product is packaged when qualification is realized. The ultra-light resin lens and the manufacturing method thereof have the beneficial effects that the resin lens is high in imaging quality and clear in imaging; the wear-resisting performance of the resin lens is greatly improved; the lens can be protected from being scratched easily; the use effects of the lens are improved; the service life is prolonged; after the antifouling film coating layer is added, the antifouling effects are good, and stains such as a fingerprint and hand scale left on the surface of the lens substrate can be avoided; and wearing by the user is more comfortable and safe.

Description

technical field [0001] The invention relates to the technical field of glasses, in particular to an ultra-light resin lens and a manufacturing method thereof. Background technique [0002] At present, the glasses products urgently needed in the market are resin lenses suitable for sports with high impact resistance, small chromatic aberration, high transmittance, and light specific gravity. Ordinary optical resin spectacle lenses are generally made of a single ADC (CR-39) monomer or resin lenses produced by diallyl isophthalate, diallyl terephthalate and their oligomers (03822475.5 / CN1522374) , this type of lens is not coated (that is, when the surface of the lens is covered with a silicone hard film and evaporated with an anti-reflection film, its impact resistance can only basically meet the US FDA (that is, a steel ball with a diameter of 16mm and a weight of 16g ​​at a distance of 1.27m) The minimum requirements for free-fall impact lenses), while the transmittance and ...
