Abstract
The utility model discloses a blue-light resistant eyeglass. A blue-light cut-off filter is made of plastic filter material. The cut-off light wavelength of the blue-light cut-off filter is 450-500nm. The plastic filter material is PC polycarbonate filter material or PMMA polymethyl methacrylate filter material. Different from the common eyeglass in the prior technology, the blue light is effectively prevented from shooting into the eye by the eyeglass, therefore the harm of the blue light on the eye is reduced to protect the eye and prevent the eye diseases such as cataract and niacula lutea retinae area pathology change and the blue-light resistant eyeglass is especially suitable for the person who had had a cataract operation, the person who has the macular degeneration familial disease, the person in the maintenance period after having had a laser operation, the student in pseudomyopia who wants to prevent the pseudomyopia degree from increasing, the person who always work or plays outdoor, the person who lives in the tropical and sunny area, the person who is taking the medicine with light sensitiveness reaction, the person who uses the computer for a long time, and the patient in xerophthalma.
Description
Technical field
The utility model belongs to a kind of eyeglass, refers in particular to a kind of anti-blue light eyeglass.
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 will select the anti-blue light eyeglass of a slave function, most of on the market Sunglasses lenses sun clips can only be kept 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 eyeglass, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of anti-blue light eyeglass, 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 eyeglass is the blue light cutoff filter that 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.
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, the person that is specially adapted to once to accept the cataract operation; the medical history person of degeneration family of macula lutea portion is arranged; the maintenance of laser operation postoperative; pseudo-myopia and the student group that wants to control number of degrees increase; outdoor activities or worker are everlasting; live in hot and the sun is shining the regional person of weather; make the medicine person of apparatus photaesthesia reaction; the person does not for a long time use a computer; 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 eyeglass 100 that the utility model discloses, be the blue light cutoff filter, adopt plastics filters such as PC polycarbonate filter or PMMA polymethylmethacrylate filter to make.
Like this, the utility model eyeglass is different from common eyeglass of the prior art, and block blue light sees through eyeglass and injects eyes effectively, is 450～500nm by wavelength of light, thereby reduces the injury of blue light to eyes, the protection eyes.
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.
