Problems solved by technology

At present, the anti-blue light glasses market is mixed with good and bad people, and there are many types, such as amethyst film, gold film, blue film, green film, yellow-green film, etc. However, these anti-blue light glasses are prone to chromatic aberration, and the anti-blue light performance is poor. When wearing, there will be glare phenomenon

Embodiment 1

[0075] A kind of anti-blue light polymer resin lens, its preparation method is as follows:

[0076] (1) Preparation of lens body

[0077] ① Dibutyl phthalate 15%, acryl alcohol 5%, isocyanate 30%, dibutyltin dichloride 0.3%, photocuring initiator 0.5%, methyl styrene balance in temperature Stir for 1 hour at 35°C, lower the temperature to 25°C and then stir for 0.5 hour, and mix evenly to obtain a mixed liquid material;

[0078] ② After the mixed liquid material is filtered, use nitrogen to pressurize the mixed liquid material into the mold and seal the mold;

[0079] ③The filled mold is cured once at 55°C for 4 hours, and the cured mold is opened to separate the mold and the formed lens;

[0080] ④ Trim the formed lens to obtain a lens with precise diameter and high-gloss edge;

[0081] ⑤ Clean the repaired lens with multi-groove ultrasonic wave, and the cleaned lens is subjected to secondary curing treatment in the curing furnace to obtain the lens;

[0082] (2) Preparat...

Embodiment 2

[0116] A kind of anti-blue polymer resin lens described in Embodiment 1, its difference is:

[0117] The raw materials of the lens body are 20% of dibutyl phthalate, 15% of acryl alcohol, 40% of isocyanate, 1.5‰ of dibutyltin dichloride, 3‰ of photocuring initiator, and more than 4% of methyl styrene. quantity.

[0118] Bisphenol A epoxy acrylate 45%, tripropylene glycol diacrylate 5%, sodium benzoate 1%, silicon dioxide 0.2%, titanium dioxide 0.2%, deionized water balance.

Embodiment 3

[0120] A kind of anti-blue polymer resin lens described in Embodiment 1, its difference is:

[0121] The raw materials of the lens body are 25% of dibutyl phthalate, 20% of acryl alcohol, 50% of isocyanate, 0.5% of dibutyl tin dichloride, 1.0% of photocuring initiator, and 1% of methyl styrene by weight percentage. quantity.

[0122] The raw materials of the coating layer are 55% by weight of bisphenol A epoxy acrylate, 5% of tripropylene glycol diacrylate, 4% of sodium benzoate, 1.5% of silicon dioxide, 1.5% of titanium dioxide, and the balance of deionized water.

Abstract

The invention provides a blue light-resistant polymer resin lens comprising a lens main body and a coating layer arranged at the outer part of the lens main body; the lens main body contains the raw material components in percentage by weight: 15%-25% of dibutyl phthalate, 5%-20% of propenol, 30%-50% of isocyanate, 0.002%-0.05% of dibutyltin dichloride, 0.06%-0.1% of photocuring initiator and thebalance of methyl styrene; and the coating layer contains the following raw material components in percentage by weight: 45-55% of bisphenol A epoxy acrylate, 1-5% of tri(propyleneglycol)diacrylate, 1-5% of sodium benzoate, 0.05-3% of silicon dioxide, 0.05-3% of titanium dioxide and the balance of deionized water. The blue light-resistant polymer resin lens is capable of effectively resisting to blue light and reducing the strength of a high beam.

Description

technical field [0001] The invention relates to a resin lens, in particular to an anti-blue light polymer resin lens and a preparation method thereof. Background technique [0002] With the development of society, the amount of information people take in has skyrocketed, resulting in an increase in myopia. Glasses have become a common commodity in our lives. The functions of glasses are also varied, such as myopia glasses, ignoring glasses, sunglasses and so on. In order to make the lens have high transparency and high strength, lens manufacturers are constantly improving the process and equipment in the lens production process. [0003] Blue light is an important part of visible light. White light in nature is a mixture of blue light, green light, and yellow light. Among them, green light and yellow light have less energy and are less irritating to the eyes, while blue light has short wavelength and high energy, and can directly penetrate the lens and reach the retina of ...
