Abstract
The utility model relates to anti-blue-light polarized light lens, which are made from a blue light edge filter and a polarizing film. The blue light edge filter is made from plastic light-filtering materials and the wavelength of the cut-off light ray is 450-500 nm long; the plastic light-filter adopts PC or PMMA as the filtering materials. The utility model can effectively prevent the blue light from entering the eyes through the lens, therefore, reducing the harms of the blue light to the eyes and protecting the eyes; in the meanwhile, the polarizing film can also effectively block the dazzling light rays caused by light scattering, light flexion, and light reflection, therefore, making the eye range more natural and clearer. The utility model is especially suitable for the following people: patients undergoing operations on cataract, people with a family record of macular deterioration, people undergoing laser operations for further attendance, people with pseudo-myopia, students wanting to control the increasing degrees, workers frequently working outdoors, inhabitants in a high-temperature climate and exposed to strong sunrays, medicine taker allergic to light, long-time computer users as well as patients suffering from dry eye syndromes.
Description
Technical field
The utility model belongs to a kind of eyeglass, refers in particular to a kind of anti-blue light polarized lenses.
Background technology
At present, a lot of places (as some test apparatuses etc.) all to light requirement to some extent, the place that has does not allow the light of a certain wave band to enter, the place that has can only allow the light of a certain wave band to enter, therefore, there has been the dealer to develop the various light transmissive materials that can end (or filtration) certain wavelength specially, as the plastics filter, specific product has ultraviolet cut-on optical filter (can shielding of ultraviolet see through), blue light cutoff filter (can block blue light see through) ... but, these materials and products thereof are mainly used in the development test at present, application in eyewear products or blank out.
The expert points out that strong ultraviolet ray is easy to eyes are damaged, and blue light can quicken the cellular oxidation in macula retinae district, excessive exposure even can damage cellula visualis.If macular area contacts blue light for a long time, can increase that the risk of ARM appears in eyes when old, even might cause eyesight forever impaired.Blue light in the sunlight can pass cornea and crystal, through retina, grievous injury is responsible for the macular area of human body ninety percent eyesight, macular area is in amphiblestroid central authorities, maximum cellula visualises are arranged, and not only eyes moved the high-risk populations that the elderly of cutter is a pathology, and the child who utilizes mydriatic to treat myopia also will avoid the blue light injury, because, may will forever lose one's sight in case cause the hemorrhagic macular diseases.
The quantity that blue light is injected eyeball has different ratios in all ages and classes section, in general, 0 to 2 years old about 70～80%, 2 to 10 years old about 60～70%, 60 to 90 years old about 20%, this shows that the harm of blue light maximum often occurs in the initial stage of people's life, so infant father and mother need guard against the injury that blue light may cause infant's eye health.There are the sun, neon light, office lighting, computer screen light, mercury halide lamp or the like in the source of common blue light.
According to statistics, at present there are 5,000,000 people of surpassing in the U.S. because macula lutea changes (degenerations) disease approximately with China, and causes the blurring of image or blind, and annual 400000 people's quantity growth, in 20 years of future, doubles increase with the increase of elderly population.Do not have effective methods of treatment at this illness, can only start with from prevention at present, do not allow blue light injure eyesight.Just to select the anti-blue light polarized lenses of a slave function, most of on the market Sunglasses lenses sun clips, can only keep out ultraviolet light or infrared ray in the sunlight, all can't keep out for can go directly the more by force blue light of macular area of seepage force, and increase the chance that eyes are suffered from maculopathy.
Based on above-mentioned realistic problem, the inventor develops a kind of anti-blue light polarized lenses, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of anti-blue light polarized lenses, with effective block blue light, reduces the injury of blue light to eyes.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of anti-blue light polarized lenses is made up of blue light cutoff filter and light polarizing film, and the blue light cutoff filter adopts the plastics filter to make.
Described blue light cutoff filter by wavelength of light be 450～500 nanometers.
Described plastics filter is a PC polycarbonate filter.
Described plastics filter is a PMMA polymethylmethacrylate filter.
Described light polarizing film is fitted in the inside surface of blue light cutoff filter.
Described light polarizing film is fitted in the outside surface of blue light cutoff filter.
Adopt such scheme, after the utility model eyeglass is selected the blue light cutoff filter for use, be different from common eyeglass of the prior art, block blue light sees through eyeglass and injects eyes effectively, thereby reduce the injury of blue light to eyes, the protection eyes, the generation of eye illnesses such as prevention cataract and macula retinae district pathology; Simultaneously, the light polarizing film of fitting on the utility model eyeglass can intercept effectively because of dazzling dazzles that various factors caused such as scattering, flexion, reflections, and makes light drop into the ocular vision image in the light transmission shaft of the right path, makes the nature that gets a clear view.
The utility model is specially adapted to once to accept cataract operation person, the medical history person of degeneration family of macula lutea portion, the maintenance of laser operation postoperative, pseudo-myopia are arranged and want to control student group, be everlasting outdoor activities or worker that the number of degrees increase, live in hot and the sun is shining the regional person of weather, make the medicine person that the apparatus photaesthesia reacts, the person that do not use a computer for a long time, xerophthalmia patient or the like.
Below in conjunction with drawings and the specific embodiments the utility model is done and to be described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, for a kind of anti-blue light polarized lenses that the utility model discloses, form by blue light cutoff filter 100 and light polarizing film 200.
Blue light cutoff filter 100 adopts plastics filters such as PC polycarbonate filter or PMMA polymethylmethacrylate filter to make, and is 450～500nm by wavelength of light.This blue light cutoff filter 100 makes eyeglass be different from common eyeglass of the prior art, and block blue light sees through eyeglass and injects eyes effectively, thereby reduces the injury of blue light to eyes, the protection eyes.
Light polarizing film 200 can be fitted in the inside surface or the outside surface of blue light cutoff filter 100.This light polarizing film 200 can intercept effectively because of dazzling dazzles that various factors caused such as scattering, flexion, reflections, and makes the nature that gets a clear view.
The above is preferred embodiment of the present utility model only, is not the qualification to the utility model practical range, and all variation and modifications of being done according to design main points of the present utility model all fall into its protection domain.
