Abstract

The utility model provides safe glasses for night walking, which changes the unique glass sheets of the ordinary glasses into the glass sheet with one layer of polarizing film in the middle. The optical axis of the polarizing film has an included angle of 45 DEG with the horizontal direction and a direction of tile which agrees with the direction of tile of the polarizing film on the glass cover of the car lamp. The utility model can be made into polarising glasses of near vision, far sight or flat light, according to different visual situations. Wearing the glasses can make the motorist or walkers see the car lamp of his own or the original light intensity without weakening, but the strong light from the car lamp from ahead darkened. So the eyes of the drivers or the walkers can not be shone and the safe traffic can be realized.

Description

Safety glasses for night walking

The utility model relates to a kind of glasses, especially the glasses of watching the car light high light of head-on sailing automobile to weaken at night.

At present, known glasses have plain glass spectacles, spectacles for long sight, spectacles, light-sensitive sunglasses, dark brown glasses several types, wear spectacles for long sight or spectacles, when running into strong illuminations such as the automobile that head-on comes, motorcycle in the walking along the street at night, it is dazzling to overcome high light, do not see the phenomenon on road surface, cause danger easily; Wear light-sensitive sunglasses or dark brown glasses,, wear at night and can not see the road surface clearly though it is dazzling to avoid automobile, Motorcycle headlight illumination to shine.

Dazzling for avoiding car light to shine, in the 298th page of the 17th row of " optics study course " book of teaching that Teaching Materials Writing Group of East China Normal University " optics " writes, introduce " with the glass for vehicle window of driver front; and the cloche of car light front is all loaded onto polaroid sheet; make their optical axis angle all at 45 with horizontal direction; and along same direction inclination; the driver sees that through vehicle window the emitted light intensity of own car light does not weaken like this; but the car light on opposite is penetrated next light, only there is micro-purple light can see through vehicle window, thereby unlikely gaudy driver's eyes ".When though this device of introducing in this book of teaching can overcome night running, the car light high light shines dazzling phenomenon, but automotive window is with a bulk of band polaroid glass, waste material not only, very uneconomical, and be only applicable to the automobile driver, and the pedestrian, that person, cyclist suffer shining of car light high light equally by motorcycle is dazzling.

The purpose of this utility model is to provide a kind of glasses, wears car light light such as the automobile that can avoid head-on coming, motorcycle during the night walking along the street and shines dazzlingly, realizes safe walking along the street, uses daytime and has the same visual field that do not influence of common spectacles now.

The purpose of this utility model is to realize like this, change the unicity glass mirror of common spectacles into polarising glass that polaroid is contained in the glass mirror middle layer, and the optical axis that makes its polaroid is from the horizontal by 45 ° of angles, and vergence direction is consistent with the polaroid vergence direction on the lamp lens cover.

The eyeglass of described safe night walking glasses, its middle layer of containing is constant, and the both sides glass sheet concaves by (concavees lens), becomes near-sighted polarising glass after the combination.

The eyeglass of described safe night walking glasses, its middle layer of containing is constant, and the both sides glass sheet becomes the long sight polarising glass to evagination (convex lens) after the combination.

The eyeglass of described safe night walking glasses, its middle layer of containing is constant, and the both sides glass sheet is that uniform thickness is parallel, becomes the zero diopter polarising glass after the combination.

Advantage of the present utility model is: owing to adopt such scheme, windowpane in face of the automobilist in the prior art is loaded onto large-area polaroid only to be changed need into load onto polaroid in eyeglass, starting material have been saved, reached effect same, but also make usable range expand motorcycle driver, cyclist and pedestrian to, make the traffic safety in night that guarantee arranged.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 is used for the cut-open view of the eyeglass that bathomorphic people wears for the utility model.

Fig. 3 is used for the cut-open view of the eyeglass that the presbyopic wears for the utility model.

Fig. 4 is used for the cut-open view of the eyeglass that the people of twenty-twenty vision wears for the utility model.

Fig. 5 is a schematic diagram of the present utility model.

Safe night walking glasses shown in Figure 1 are made up of mirror holder 1 and eyeglass 2, the utility model is characterized in that the middle layer of its eyeglass 2 of glasses contains polaroid 4, two sides are glass sheet, and the optical axis of polaroid 4 is from the horizontal by 45 ° of angles, and vergence direction is consistent with the polaroid vergence direction on the lamp lens cover 11.

The cut-open view that is used for the eyeglass 2 that bathomorphic people wears for the utility model shown in Figure 2, the middle layer that this eyeglass 2 is contained is that polaroid 4 is constant, the glass sheet 3,5 of both sides concaves by (concavees lens), and according to the degree difference of myopia, the concavity of being joined has different simultaneously.

The cut-open view that is used for the eyeglass 2 that the presbyopic wears for the utility model shown in Figure 3, the middle layer that this eyeglass 2 is contained is that polaroid 4 is constant, the glass sheet 6,7 of both sides is to evagination (convex lens), according to the degree difference of long sight, protruding degree have different.

Fig. 4 is used for the cut-open view of the lens 2 that the people of twenty-twenty vision wears for the utility model, and the middle layer that this eyeglass 2 is contained is that polaroid 4 is constant, the glass sheet the 8, the 9th of both sides, and uniform thickness is parallel.

Fig. 5 is a schematic diagram of the present utility model, complanation polarized light 12 behind the polaroid of natural light 10 in lamp lens cover 11 that the car light bulb sends, linearly polarized light 12 is in eyeglass 2 behind the polaroid 4, the light that shows is very dark only little bright purple light, just not dazzling, reached the purpose of safe walking along the street.

Claims (4)

1, a kind of safe night walking glasses, it includes mirror holder 1 and eyeglass 2, of the present utility model being characterised in that: polaroid 4 is contained in the middle layer of its glass mirror 2, and the optical axis of polaroid 4 is from the horizontal by 45 ° of angles, and vergence direction is consistent with the polaroid vergence direction on the lamp lens cover.
