Abstract
The utility model relates to an eyeglass for night driving. The central zone of the eyeglass is provided with a high transparent zone having an area which is larger than 5 square millimeters but smaller than 20 square centimeters and the visible light transmissivity is 75 %-100 %, and a light weakening layer whose visible light transmissivity is 3 %-49 % is arranged out of the high transparent zone. After the eyeglass for night driving of the utility model is assembled into a driving eyeglass, dipped headlights can be attenuated more than 70 %, and the visible light transmissivity of the central zone of the eyeglass can be ensured for more than 75 %; the light weakening layer has reasonable design, little light reflection, beauty and comfort. After a driver wears the eyeglass for night driving, road articulation is high, the driver can feel comfortable after wearing for a long time, eyes are not easy to feel fatigued, the effects of preventing high beam glaring eyes, preventing fatigue and safety are obtained, and traffic accidents are not easy to happen.
Description
Technical field
The utility model relates to optical mirror slip, particularly a kind of nighttime driving eyeglass.
Background technology
Speed with millions of is increasing automobile in China every year, and the frequency of driving at night is also more and more higher, but the dazzling light of dazzle light makes the driver on opposite not see the road surface.The numerous traffic hazard of annual generation.The anti-dazzling safety to each driver of high beam has significance.Present commercially available nighttime driving eyeglass, be Sunglasses lenses sun clips in essence, its center of lens zone, the transmittance of visible light (transmittance)＜50%, a part of dazzling light though this nighttime driving usefulness eyeglass can be decayed also reduces the brightness on road surface more than 50% simultaneously.Another kind of nighttime driving eyeglass is dark brown polariscope, this driving mirror is because can be with the polarized light decay of a certain direction, its theoretical transmittance can not surpass 50% yet, two kinds of above-mentioned nighttime driving eyeglasses, because the central area of eyeglass is too dark, the luminous energy that enters driver's eyes is too little, and driver's eye pupil is in magnifying state for a long time, very easily tired, cause traffic hazard easily.And transmittance is greater than 75% eyeglass, as common near-sighted glasses or common yellow eyeglass, its light extinction rate is no more than 25%, and human eye is almost imperceptible the dim light effect, still very dazzling to high beam, so above-mentioned eyeglass is not suitable as the dazzling driving mirror that ensures safety of anti-high beam that the driver uses night.
The utility model content
The purpose of this utility model is to address the above problem, a kind of nighttime driving eyeglass is provided, after being assembled into driving mirror, both can decay meeting beam more than 70%, the transmittance that can guarantee center of lens zone visible light again reaches more than 75%, and more reasonable, reflective littler, the aesthetics of the design of dim light layer and comfort level are better.
The technical solution of the utility model is:
A kind of nighttime driving eyeglass, it is characterized in that: the central area of eyeglass be provided with area greater than 5 square millimeters less than 20 square centimeters, visible transmission than being the high clear area of 75%-100%, be outside equipped with visible transmission in high clear area than being the dim light layer of 3%-49%.
Described dim light layer is a kind of or its combination in the vacuum coating rete of organic pigment dye penetration layer or metal, metal oxide, and the thickness of this dim light layer is the 0.02-5 micron.
The central area of described eyeglass is to comprise center of lens, with the center of lens is the center of circle, diameter is at least 5 millimeters round territory, when described eyeglass excision center cooperates with the lower part and with picture frame or makes magnetic sheet, rotating sheet, the central area of described eyeglass is the central area of the picture frame that cooperates with it, and described high clear area is shaped as a kind of or its combination in triangle, circle, ellipse, rectangle or the polygon;
Described dim light layer be shaped as a kind of in triangle, circle, ellipse, rectangle or the polygon or its combination, the area of this dim light layer is between 20 square millimeters to 15 square centimeters.
Described dim light layer be arranged on the oblique upper in center of lens zone, tiltedly the below, directly over, under a kind of or its combination in the position.
The transmittance of described dim light layer by the center of lens zone to directly over or under obliquely upward or to oblique below successively decrease or simultaneously to directly over, under successively decrease, or simultaneously obliquely upward, successively decrease, or equally distributed constant transmittance to oblique below.Under the color of dim light layer be a kind of or its mixing in green, dark brown, yellow, salmon pink, the grey.
Described pervious course is an azo-compound, and this azo-compound is a kind of in the different proportion prescription of biacetyl acetyl arylamine class azo-compound or pyrazolone bis-azo compound and azoic coupling component AS serial pigment.Under high clear area be a kind of in the hollow air layer that forms after yellow, dark brown, colourless eyeglass or the excision mirror sheet material.
Described lens materials is a kind of in CR-39 resin, polycarbonate, acrylic, polaroid, organic glass, optical glass, photochromic resin, the photochromic glass.
One or both the combination that the diopter of eyeglass and astigmatism are 0 degree to 1200 degree.
The utility model has following advantage and positive beneficial effect:
Nighttime driving eyeglass of the present utility model, the central area of eyeglass is provided with the appropriate high clear area of area, its area is between 5 square millimeters to 20 square centimeters, the transmittance of high clear area visible light reaches more than 75%, after the driver is worn, the road surface sharpness is higher, is not easy to take place traffic hazard; Simultaneously, the position of dim light layer is reasonable, wear for a long time more comfortable, the also more difficult fatigue of eyes.The visible transmission of dim light layer is than being 3%-49%, can decay meeting beam more than 70%, the dim light effect is remarkable, solved the difficult problem of night, played dazzling, anti-tired, the effect that ensures safety of anti-high beam with this mutual contradiction of driving mirror " should dim light effective; road surface brightness height again ".
