Abstract

The invention belongs to the technical field of lens of eyeglasses, and specifically provides a blue-ray preventing resin lens. The blue-ray preventing resin lens comprises a base body; a first hardening layer, a first crack preventing layer, a blue-ray film structure and a fouling preventing film coating layer are arranged on the front surface of the base body from inside to outside in a sequence; a second hardening layer, a second crack preventing layer and an antireflection film layer are arranged on the rear surface of the base body from inside to outside in a sequence. According to the blue-ray preventing resin lens, the hidden cracks between the hardening layers and other film layers can be reduced by the crack preventing layers, so that the surface quality of the lens can be improved; the damage of the blue ray to the eyes after transmitting through the lens can be effectively reduced.

Description

A kind of anti-blue light resin lens

Technical field

The invention belongs to lens technical field, be specifically related to a kind of anti-blue light resin lens.

Background technology

The parent more and more obtaining consumer along with advantages such as resin lens is lightweight with it, anti-vibration, easy dyeing, easy-formations, preferably elasticity, high index of refraction, uvioresistant looks at, but due to self shortcomings such as low, the easy scratch of its skin hardness, thermal behavior differences, make surface carry out processing process and seem more and more necessary.

Blue light is the important component part of visible ray, and nature itself does not have independent white light, presents white light after blue light and green glow, yellow light mix.Green glow and gold-tinted energy less, less to eye irritation, blue light ripple is short, and energy is high, can directly penetrate crystal and go directly on eye ground.If the blue violet exposure of the long-time chronic acceptance of research display photosensory cell, the pigment molecular in cell can trigger phototoxic reaction, and make macula area produce pathology, light injures more by force larger.Therefore, macular diseases is no longer the patent of old man, present society, along with the change of habits and customs, the long-time stimulation (as computer, TV, outdoors sunlight etc.) in the face of royal purple light, especially today TV, computer, touch-screen mobile phone universal epoch, eye health has become a large problem.For we normal person, intercepting that blue light irradiates for a long time is reduce damage most effectual way, and uses anti-blue light eyeglass effectively can solve this point, and common UV resistance eyeglass can only ultraviolet ray filtering, and can not filter blue light.

In addition, by a large amount of productions of reality, find that there is quite a few plated film lens after plated film places a period of time, its junction surface adding hard membrane layer and other rete there will be the hair check spreading shape, and namely insider is called the defect of dark crackle more.Particularly testing through 24h salt bubble, this defect is more obvious.

Summary of the invention

The object of the invention is the defect overcoming prior art, provide a kind of blue light that can weaken to stimulate and the anti-blue light resin lens that can improve lens surface quality.

For this reason, the invention provides a kind of anti-blue light resin lens, comprise eyeglass matrix, the front surface of described eyeglass matrix is disposed with the first stiffening layer, the first anticracking lamina, blue Light Film structure and antifouling film plating layer from inside to outside; The rear surface of described eyeglass matrix is disposed with the second stiffening layer, the second anticracking lamina and antireflective coating from inside to outside.

Described first anticracking lamina and the second anticracking lamina are made up of chromium oxide rete or aluminium oxide rete.

Described antifouling film plating layer is fluoride layer.

Described blue Light Film structure has seven layers, is followed successively by silicon oxide layer, titanium oxide layer, silicon oxide layer, titanium oxide layer, ITO layer, silicon oxide layer and alumina layer from inside to outside.

Beneficial effect of the present invention: this anti-blue light resin lens provided by the invention, improving by arranging anticracking lamina the dark crackle existed between stiffening layer and other rete, improve the surface quality of plated film resin lens.Effectively reduce blue light through the injury of eyeglass to eyes.

Description of reference numerals: 1, eyeglass matrix; 2, the first stiffening layer; 3, the first anticracking lamina; 4, blue Light Film structure; 5, antifouling film plating layer; 6, the second stiffening layer; 7, the second anticracking lamina; 8, antireflective coating.

Embodiment

Below in conjunction with the drawings and specific embodiments, illustrate the present invention further.

Present embodiments provide a kind of anti-blue light resin lens, as shown in Figure 1, comprise eyeglass matrix 1, the front surface of described eyeglass matrix 1 is disposed with the first stiffening layer 2, first anticracking lamina 3, blue Light Film structure 4 and antifouling film plating layer 5 from inside to outside; The rear surface of described eyeglass matrix 1 is disposed with the second stiffening layer 6, second anticracking lamina 7 and antireflective coating 8 from inside to outside.Described first anticracking lamina 3 and the second anticracking lamina 7 are made up of chromium oxide rete or aluminium oxide rete.

Described first stiffening layer 2 and the second stiffening layer 6 are organosilicon, and thickness is between 2.5-3.5 μm, and energy available protecting resin lens, makes eyeglass have good toughness and hardness; Described first anticracking lamina 3 can improve the dark crackle existed between the first stiffening layer 2 and blue Light Film structure 4, the adhesion between both raisings rete.Described second anticracking lamina 7 can improve the dark crackle between the second stiffening layer 6 and antireflective coating 8, the adhesion between both raisings rete.

Described antifouling film plating layer 5 is fluoride layer.Under the prerequisite ensureing eyeglass transparent effect, antifouling coating structure, as protective finish, can prevent eyeglass matrix surface from leaving the spot such as fingerprint, hand dirt.

Antireflective coating can improve the total light transmittance of plated film resin lens.

Described blue Light Film structure 4 has seven layers, is followed successively by silicon oxide layer, titanium oxide layer, silicon oxide layer, titanium oxide layer, ITO layer, silicon oxide layer and alumina layer from inside to outside.The thickness of each layer is followed successively by silicon oxide layer 155 nanometer-165 nanometer from inside to outside, preferably 160 nanometers; Titanium oxide layer 170 nanometer-180 nanometer, preferably 175 nanometers; Silicon oxide layer 25 nanometer-35 nanometer, preferably 30 nanometers; Titanium oxide layer 55 nanometer-65 nanometer, preferably 61 nanometers; ITO layer 3.5 nanometer-4.5 nanometer, is preferably 4 nanometers; Silicon oxide layer 70 nanometer-80 nanometer, is preferably 75 nanometers; Alumina layer 30 nanometer-40 nanometer, is preferably 35 nanometers.The present embodiment is for royal purple light predominant wavelength, resin lens carries out anti-blue light technique plated film, royal purple light is made to reflect weakened part through this eyeglass, reduce its transmitance and greatly can alleviate the stimulation of royal purple light to eye eye, eliminating that eyes are sour and astringent, heating or the malaise symptoms such as pain, relieving eye strain, be widely used, operation is simple, and production cost is low, is suitable for suitability for industrialized production.

More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
