Embodiment 1

[0026] Embodiment 1: with reference to attached figure 1 Shown, a kind of anti-fatigue safety lens, described lens comprises a resin substrate and the exterior coating on its surface, and described exterior coating is hard coating layer, and the thickness of described hard coating layer is within 5 μm, and the The above-mentioned hardened coating layer includes an antistatic agent, an absorbent, an additive, and a hardening liquid. The absorbent can block harmful blue light of 380nm-420nm, and the additive can block visible light with a narrow band wavelength near 585nm; the antistatic agent is SN anti- Static agent, the dosage is between 0.01% and 5%. The absorber is light stabilizer TM46, which can absorb harmful blue light from 380nm to 420nm. The dosage is between 0.1% and 5%. The additive is functional Absorber ABS584, which can absorb 60%-90% of 585nm narrow-band visible light, the addition amount is between 0.1%-5%; the hardening liquid includes one or more of water, me...

Embodiment 2

[0034] Embodiment 2: Different from Embodiment 1:

[0035] 2) Solution preparation: Add specific 1.0% TM46 anti-blue light machine, 200PPM SN antistatic agent and 1.0% ABS584 visible light absorber to MP7110 hardening machine used for hardening machine, stir and mix well, then add 5μm for hardening machine The filter element circulates for 24 hours;

Embodiment 3

[0036] Embodiment 3: Different from Embodiment 1:

[0037] 2) Solution preparation: Add specific 1.0% TM46 anti-blue light machine, 500PPM SN antistatic agent and 1.0% ABS584 visible light absorber to the hard top coating MP7110 used for the hardening machine. After fully stirring and mixing, add 5 μm for the hardening machine The filter element circulates for 24 hours.

[0038] The process of the present invention is suitable for resin lens substrates whose refractive indices are 1.499 (CR39), 1.56 (KOC55 and NK55), 1.53 (trivex), 1.59 (PC) and 1.60, 1.67, 1.74 Mr series.

Abstract

The invention discloses anti-fatigue safety glasses and a production method thereof. The anti-fatigue safety glasses comprise a resin substrate and a special coating arranged on the surface thereof, a special antistatic agent and a special absorbent need to be added to the external coating, and the antistatic agent refers to one or more internal-mixing type antistatic agents. According to the antistatic glasses with the coating, static electricity on the resin glasses can be effectively, rapidly, and permanently led out, the usage is safer, and the surface of the glasses is more stain-resistant; two special absorbents are added to the external special coating, harmful blue light of the 420 nm can be blocked, narrowband visible light of the 585 nm, which causes visual fatigue, can be effectively absorbed, and eyes can be protected more comprehensively.

Description

technical field [0001] The invention relates to the technical field of lens manufacture, in particular to the manufacture of an anti-fatigue safety lens. Background technique [0002] Due to the gradual improvement of the quality of human life, the demand for diversified functions of lenses is also increasing, such as anti-fatigue, driving glasses, computer progressive lenses and so on. With the rapid development of lenses in recent years, the types of lenses are becoming more and more diversified. Sports glasses, labor insurance glasses, polarized sunglasses, etc. can basically meet the different daily needs of customers. [0003] Optical glass and optical resin lenses are currently used on the market. The use of resin sheets is relatively extensive; resin lenses have the same characteristics: insulation, easy to generate static electricity accumulation during use, resulting in vacuuming, electric shock, and even sparks that lead to explosions and other vicious accidents. ...
