Abstract
The invention discloses a polarized lens and a method for manufacturing the same. In the process of manufacturing the polarized lens of the invention, a poly vinyl alcohol (PVA) membrane is inserted between a tri acetyl cellulose (TAC) membrane and a cellulose acetate propionate (CAP) membrane or between the tri acetyl cellulose (TAC) membrane and a polymethyl methacrylate (PMMA); or materials with different chemical properties and physical properties are attached to two sides of the poly vinyl alcohol (PVA) membrane, and then the polarized lens is manufactured. The polarized lens is used for preventing foreign matters from hurting eyes or dazzling caused by light rays, and has excellent transparency.
Description
Technical field
The present invention relates to a kind of polarized lenses and manufacture method thereof.The present invention utilizes the interference of light phenomenon to prevent the function of dazzling the eyes, at skiing, skis, skate ship, bicycle, sports field or manufacturing industry such as motorcycle, in the industrial field such as building building etc. in order to prevent that because of direct light what reflected light caused dazzles the eyes, and prevent wind, avenge rain, seawater, water, sand, medicine, foreign matter etc. use in goggles that uses and glasses eye injury.
Background technology
It is the macromolecule resin polarized lenses of main material that general polarized lenses all is to use by glass material and high molecular synthetic resin, but the polarized lenses of the glasses that are made with high molecular synthetic resin is attached most importance to the eyeglass that does not have the number of degrees and produced.
In the above-mentioned polarized lenses manufacture method, used the method for pasting light polarizing film on forward and backward of CR39 eyeglass, but it is very big to be subjected to the influence of alite paste and light polarizing film like this, the overlong time that needs during making, production efficiency is low, can be subjected to very large limitation as a large amount of productions.
That is to say from general sunglasses and can't stop the light of dazzling the eyes that comes into view, can stop by vertical light polarizing film eyeglass, make the visual field relatively distincter, elimination is because of dazzling the eyes that reflected light causes, but such polarized lenses shortcoming is, light polarizing film is directly sticked on the lens surface, so that the efficiency of polarisation and light polarizing film are thought the correct center that is positioned at eyeglass is also very difficult, also have outside impact can be very easy to cause the breakage of light polarizing film, the performance as eye plate is reduced.
The polariscope that utilizes the PC eyeglass in addition is to be the simple polarisation function that added on the sunglasses effect for the shortcoming of no number of degrees eyeglass, not to make by the method for casting, so limited as the auxiliary function of people's eyesight with lens, be processed into presbyopic glasses and process very difficulty according to eyesight.
Disclose among the Japanese kokai publication hei 8-52817, energy with the radiation of light form can cause or promote certain photochmeical reaction, and the effect that various photochmeical reactions act on the light (or photon) of various wavelength is widely known by the people, polarized lenses by this principle is that light polarizing film is clamped light polarizing film with two-layer polycarbonate membrane, insert Polarizer mould the inside, by heat-treating profiled method
But the method is after inserting with cutting after the one-stop operation of TAC-PVA-TAC Polarizer, thickness to be processed, so production efficiency is very low, supplies very slowly, is a kind of product of nonproductive type so original cost can rise.That is to say that this process is to Triafol T (TAC; Tri Acetyl Cellulose)+polyvinyl alcohol (PVA) (PVA; Poly Vinyl Alcohol)+Triafol T (TAC; Tri Acetyl Cellulose) carry out one-stop operation after, do not reach the desired thickness of lens, so form CR polarisation, PC polarisation after replenishing CR or PC; Also having a kind of TAC polarisation is Triafol T (TAC; Tri Acetyl Cellulose)+Triafol T (TAC; Tri Acetyl Cellulose)+polyvinyl alcohol (PVA) (PVA; Poly Vinyl Alcohol)+Triafol T (TAC; Tri Acetyl Cellulose)+Triafol T (TAC; Tri Acetyl Cellulose) etc. carry out the method that multilayer is adhered to, so but adhere to solvent and can cause the low situation of transparency because of all using adhering to of multilayer.
In order to address the above problem, when making polarized lenses now at Triafol T (TAC; Tri AcetylCellulose) between the film or at cellulose acetate propionate (CAP; Cellulose Acetate Propionate) inserts polyvinyl alcohol (PVA) (PVA between the film; Poly Vinyl Alcohol) film only to the material use polarized lenses with a kind of character, but can not satisfy the consumer like this to preventing the injury that eyes is caused from foreign matter or preventing to produce the requirement of dazzling the eyes because of light.That is because Triafol T (TAC; Tri Acetyl Cellulose) produces thickness as the main raw material(s) of lens and be generally 0.04mm to 0.245mm, the lens of making 1.0mm thickness will adhere to four layers at least, if want to make the more satisfactory thickness 2.0mm of lens, that will adhere to eight layers, so can be because of bonding agent and cause transparency low and operating efficiency and the very low shortcoming of production at many levels.
