The utility model has the advantage of long service life, and lenses can not abraded easily.

Description

Teleputer video screen sight protectio glasses

The utility model relates to a kind of extraordinary coating glasses, particularly a kind of video screen sight protectio glasses of using when seeing TV, operating computer.Also be available as the eye-protecting health mirror of daily life.

Along with quick development of modern science and technology, robot calculator has been penetrated into the every nook and cranny of each department of national economy and society.The televisor of all size has spread in each family.Harmful light that computer, television screen send has caused people's attention to the injury of human eye.Because harmful light (X ray, ultraviolet ray, the purple blue streak) cumulative effect of luminous energy and the flicker of fluorescent screen images light and shade change, the photochemical effect of human eye vision process, too fast the having little time of rhodopsin consumption synthesized on the retina, make the visual pigment unevenness between supply and demand on the retina, cause kopiopia or temporary visual deterioration.Be the protection eyes, existing people adopts light-sensitive glasses or with resin lens dyeing, but it can only anti glare anti static coatings and anti-harm ray.Also the someone adopts common film plating process to make safety goggles, and promptly plating layer of metal pottery nesa coating on optical mirror slip or color-changing lens plates one or more layers deielectric-coating, again with antiultraviolet.But its function singleness though have certain filter action, is protected the order poor effect, due to its main former transmitted spectrum distribution proportion that is the eyeglass filter coating is improper.

The purpose of this utility model provides a kind of teleputer video screen sight protectio glasses; it effectively overcomes the shortcoming that prior art exists; it is effective to have the harmful light of filtering; obviously slow down the consumption that the human eye retina goes up rhodopsin; promote the balance between supply and demand effect of visual pigment; thereby reach the generation that alleviates visual fatigue, eliminates or alleviate " computer illness in eye ", the purpose of protection eyes.Eyeglass is anti-in wiping, and is durable in use.

The purpose of this utility model is achieved in that this device comprises spectacle frame and assembles lens on it, wherein be coated with the multi-coated interference filter coating that different dura mater materials replace evaporation mutually at the lens inside surface, the spectral characteristic of this film is: the insensitive ultraviolet light transmitance of vision is not more than 3%, the transmitance of shortwave light increases with the increase of its visual sensitivity, and quick-eyed long wave light penetration is not less than 80%.

Because lens inside surface of the present utility model is coated with the multi-coated interference filter coating that different dura mater materials replace evaporation mutually, so this rete not only has very strong binding ability with lens substrate, can stand clean wiping, durable in use, and rete has the spectral characteristic of setting, improved the ultraviolet (uv) transmission attenuation rate, eliminated the damage of ultraviolet ray to human eye, it is approaching that the eyes spectrum that makes shortwave light see through vision standard luminosity observer in the curve of spectrum and the International Commission on Illumination (CIE) is experienced curve, therefore make that the teleputer video screen sends be easy to consume the human eye vision rhodopsin and to looking the little shortwave light of thing brightness contribution by the part filtering, promote the balance between supply and demand of visual pigment, prevent effectively that to of the stimulation of the insensitive short wavelength light of vision the harmful light of filtering is effective to human eye.Be not less than 80% to looking the big long wave light penetration of thing brightness contribution, effectively utilized energy to quick-eyed longwave optical, improve human eye vision brightness, visual sense is comfortable, look the thing sharpness and improve, further alleviate visual fatigue, prevent that eyesight from reducing, eliminate " computer illness in eye ", play the eye-protecting health effect.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure synoptic diagram of the utility model.

Fig. 2 is the cut-open view of Fig. 1 along the A-A line.

Describe concrete structure of the present utility model in detail according to Fig. 1-2.This spectacle frame 2 can be selected according to wearer's hobby, and the lens of assembling on it 1 adopts optical glass sheet 3 and the surperficial multi-coated interference filter coating 4 that is replaced evaporation by different dura mater materials mutually that is coated with within it.The number of plies of interference light filtering film 4 can be determined by the spectral characteristic of setting.Optical glass sheet 3 can be the plain glass spectacles sheet, also can be to have various dioptric lenses, to adapt to people's needs of different eyesights.Used dura mater material can be selected for use according to actual needs, but preferentially select the metal oxide of tantalum oxide, titanium dioxide composition and the nonmetal oxide that monox is formed for use, adopt conventional Vacuum Coating method, replace evaporation multi-coated interference filter coating 4 respectively at optical glass sheet 3 inside surfaces.The spectral characteristic of the lens 1 of plating multi-coated interference filter coating 4 can reach the insensitive ultraviolet light transmitance of vision is not more than 3%, and quick-eyed long wave light penetration is not less than 80%.

On probation with the scene after testing, the spectral characteristic index of the utility model coating glasses sheet 1 is:

The ultraviolet ray transmissivity of wavelength 300-380nm wave band is not more than 0.3%;

The ultraviolet ray transmissivity of wavelength 380-400nm wave band is not more than 3%;

Wavelength is not less than 80% greater than the visible light transmissivity of 480nm wave band;

The integral mean of the purple blue streak transmitance of wavelength 400-480nm wave band is 30%-50%, and light penetration increases with the increase of light visual sensitivity.

This shows, lens 1 is the ultraviolet ray of filtering 100% almost, prevented the ultraviolet damage of accumulating of before computer, working for a long time, part filtering shortwave light, eliminate the part dazzling light, and don't reduced and look thing brightness, helped the bleaching and synthetic molecular balance of rhodopsin, thereby alleviate visual fatigue, prevented the blue streak damage.

At the long period of operation computer or when seeing TV, wear the utility model glasses, can carry out the eye protection to the operating personnel before the video screen, the generation of obviously eliminating or alleviating computer illness in eye, efficient more than 99%.Daily wearing with the eye-protecting health effect is also arranged.
