Abstract
An anti-blue-light resin lens made from a fluorescent masking agent is manufactured in the following steps of (1) monometer preparation, (2) pouring, solidification, demoulding and stabilization and (3) hardening and film coating according to percentage by weight. According to the anti-blue-light resin lens, the broadband fluorescent masking agent is added into a lens monometer according to a certain ratio and is evenly dispersed, as a result, 99 percent of ultraviolet light, with wave length ranging from 220 nanometers to 380 nanometers, harmful to the human body can be attenuated through absorption, part of purple light and blue light with wave length ranging from 400 nanometers to 480 nanometers is attenuated through absorption in a relatively linear mode at the same time, in this way, original anti-blue-light capacity of a lens is remarkably improved on the premise that high light transmittance of the lens is guaranteed, and the blue light attenuation rate is increased to over 40 percent from originally 10-20 percent after film coating, linear adjustment of blue light frequency attenuation is realized, and the anti-blue-light resin lens has the advantages of being advanced in technology, simple in process, high in practicability and capable of selectively adjusting the blue light frequency attenuation rate.
Description
Technical field
The present invention relates to anti-blue light resin lens and make applied technical field, refer to especially a kind of anti-blue light resin lens that uses fluorescent screening agent to make.
Background technology
Scientific research proves: wavelength at the blue light of 400-480nm because wavelength is short, the high potential hazard that people's eyes are caused of energy is very large, blue light can directly penetrate crystal and arrive on the retina of eyeground, cause ophthalmic uncomfortable, visual fatigue, cause the decline of retinal pigment epithelium, the irradiation that is subject to for a long time high strength blue light can cause macula retinae portion pathology, produce blurred vision, the consequence of visual impairment, the infringement causing for people's eyes in view of blue light has been confirmed by medical science and has confirmed, so progressively caused the manufacturing great attention of medical circle and glasses, various minimizings are arisen at the historic moment with the lens product that stops blue light to see through, 201310408405.4 1 kinds of anti-blue light resin lens method for makings of Chinese patent and product have adopted the method for dosing blue-light absorbers (olp melanin powder) in heat curing-type optical resin monomer to absorb and scattering blue light energy, reduced passing through of blue light, it is reported, when the addition of olp melanin powder is during at 600-800ppm, the product of making can stop more than 90% blue light, but olp melanin powder belongs to the light absorbent of wide spectral type, its advantage is as purple light to high-frequency shortwave light, the shielding factor of blue light is greater than the decay shielding factor to low frequency light wave, but itself there is no window absorption frequency, cannot realize the rectangle cutoff characteristic to blue light, in decay blue light, also reduce passing through of other frequency coloured light, reduced the integral light-transmitting rate of eyeglass.
Chinese patent 201320761157.7 anti-blue light eyeglasses, by increased vacuum evaporation In2o3 rete and Ti2o3 rete on substrate, coordinate the stack filter effect of other evaporation retes, and blue light attenuation rate has been reached more than 40%, have effectively filtered blue ray radiation; 201320664107.7 1 kinds of plated film anti-blue light resin lens of Chinese patent, by at the different rete of substrate surface vacuum evaporation refractive index, also played the effect of decay blue light, but the technical scheme of above-mentioned binomial patent documentation is all the technology path of having followed stack decay, cannot form the window regulation and control to the strong specific aim decay of blue light shield effectiveness, meanwhile, Multideck film plating layer has also caused the relative raising of production cost.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of anti-blue light resin lens that uses fluorescent screening agent to make, in lens monomer, to have mixed by a certain percentage and dispersed a kind of broadband fluorescent screening agent, after dispersed with stirring is even, pump bubble, inject in glass for lenses mould the anti-blue light resin lens of making after by imposing a condition, Unit heating being solidified.
Technical scheme of the present invention realizes in the following manner: a kind of anti-blue light resin lens that uses fluorescent screening agent to make, by weight percentage, comprises the following steps: it is characterized in that:
1), monomer preparation: at room temperature resin lens monomer is injected in stainless steel preparing tank, taking the diisopropyl peroxide carbonic ether initiating agent, 0.01% phthalic acid fat plastifier and the fluorescent screening agent of 0.01-0.04% that account for resin lens monomer weight 2.5-3% adds in tank, under normal pressure power, be uniformly mixed, degasification, make to vacuumize purification after liquid and bubble separation, make the filling monomer of eyeglass, then put into congealer, keep-10 ℃ and save backup;
Described fluorescent screening agent is to shelter the HY-101A wide spectrum fluorescent screening agent that frequency wavelength is 220-480nm;
2), by the conventional manufacture craft of resin lens, carry out die perfusion, solidified forming, demoulding program and stable processing and make the optical resin lens substrate that includes fluorescent screening agent;
3), technological requirement is carried out stiffened plated film, vacuum evaporation antireflecting film to optical resin lens substrate routinely, makes anti-blue light resin lens.
The present invention: mixed by a certain percentage in lens monomer and dispersed a kind of broadband fluorescent screening agent, can be harmful wavelength purple light and the blue light of relative linear attenuation absorption portion wavelength between 400-480nm from ultraviolet light 99% attenuation by absorption of 220-380 nanometer time, under the precondition that guarantees eyeglass light high permeability, the original anti-blue light ability of eyeglass is significantly improved, by the blue light attenuation rate 10-20% after original plated film, be increased to more than 40%, realized the linear regulation to blue frequencies decay, advanced person possesses skills, technique is simple, practical, the alternative feature that regulates blue light attenuation rate.
