Abstract

The utility model provides a pair of improved anti-dazzling spectacles for all-weather drivers. The eyeglass is glued by a layer of colored optical glass and a layer of discolored optical glass or is made in the way that a plurality of dielectric film layers are coated on optical glass. The anti-dazzling spectacles can solve the problem that drivers are dazzled by head lamps of opposite vehicles when driving at night without weakening the visibility in front of drivers, which reduces the accident rate; the anti-dazzling spectacles can prevent sunlight dazzling drivers. If drivers wear the utility model at night or at daytime for a long time, the fatigue of eyes can be reduced.

Description

The anti-glasses of dazzling of round-the-clock driver

The utility model is the improvement of former " driver's night vision goggles " (patentee Wang Guang human relations, the patent No. are 91223441.5), wears when particularly being suitable for automobilist's night and daytime driving, so claim round-the-clock driver the anti-glasses of dazzling.

During the nighttime driving automobile meeting headlight for vehicles often meeting driver order dazzle (dazzling), traffic hazard takes place easily.For this reason, driver's nighttime driving must be worn the anti-mirror of dazzling.Night vision goggles in the market generally all are that yellow plastic or yellow organic glass make.This night vision goggles only are that white light is become gold-tinted, filter the light of a part of wavelength, but thoroughly do not solve dazzling problem.The night vision goggles of plastics or organic glass eyeglass making are simultaneously worn the health care that also is unfavorable for driver's eyes for a long time.

The purpose of this utility model provides the anti-glasses of dazzling of a kind of novel round-the-clock driver.It can reduce looking of the other side's light and see brightness, and is not dazzling, does not reduce the preceding diopter of one's own side's car simultaneously, and driver's eyes is played a protective role.

The utility model utilizes the optical characteristics and the optical principle of human eye, adopts coloured optical glass of LB6 and color-change optical glass cement to lump together; Or utilize technique for vacuum coating with color-change optical glass, plate multilayer dielectric film.It is the anti-glasses of dazzling of round-the-clock driver that the eyeglass that utilizes said method to make is made glasses.

The glasses that plating multilayered medium film method is made on coloured optical glass gummed that the utility model provides or the optical glass, only allow the highest light of human eye luminosity function pass through, be that wavelength is near the light the 550nm, the light of all the other most wavelength is filtered, use color-change optical glass to be substrate, looking to external world sees that luminance brightness will play regulating action.Like this; wear the glasses that the utility model provides; during the nighttime driving meeting; can be not dazzling to quad headlight, but the diopter before the square car do not reduce, thus significantly reduced the possibility that traffic hazard takes place; and the glasses that provide of the utility model are not worn for a long time and can be damaged eyes; comfortable, because filter ultraviolet ray and infrared ray, eyes there is protective effect.The glasses that the utility model provides also can be worn by day for people, prevent that sunlight is dazzling, and the cloudy day, the rainy day has been worn bright sense.

Provide two embodiment and accompanying drawing thereof below, and be further described.

Fig. 1 is a cemented type eyeglass diagrammatic cross-section.(1) one color-change optical glass among the figure, (2) one optical lens gelatin, the coloured optical glass of (3) one LB6 (or LB11, LB17).The selection of optical glass material and thickness should make them satisfy near the light that only allows the highest light wavelength 550nm of human eye luminosity function when gummed is formed eyeglass and pass through.And filter the condition of other most of visible lights.

Fig. 2 is the anti-lens diagrammatic cross-section of dazzling of plated film type driver.(4) one variable color or colouless optical glasses among the figure, (5) one deielectric-coating, it plates with technique for vacuum coating, and multilayer can obtain better effect so often.It is only to allow the light of the highest part wavelength of human eye luminosity function to pass through that multilayer Jie's film plated film requires.Use film plating process can obtain than the more gratifying result of cemented type.

The glasses that utilize above-mentioned eyeglass to make, promptly round-the-clock driver is anti-to dazzle glasses, can reduce driver's night or daytime long-duration driving to the degree of fatigue of eyes, significantly reduce accident rate, have tangible economic benefit and social benefit.

Claims

1, round-the-clock driver prevents that dazzling glasses is made up of mirror holder and eyeglass, it is characterized in that eyeglass is to use the optical clear glue glued adhesion to form by LB6 (LB11, LB17) coloured optical glass and photochromic optical glass, also can make by photochromic optical glass plating multilayered medium blooming.

2, the anti-glasses of dazzling of round-the-clock driver according to claim 1 is characterized in that photochromic optical glass plating multilayered medium blooming, and its rete is made up of zirconia, silicon dioxide, nickel-chrome.

3, prevent dazzling glasses according to claim 1, the 2 described round-the-clock drivers that make, it is characterized in that the curve of spectrum meets with the human eye luminosity function basically.
