CN2031535U - Anti-glare glasses for driving at night - Google Patents

Abstract

The utility model relates to anti-glare glasses for driving at night, whose technical proposal is that the upper part of horizontal visual center line is a local transparent area and the lower part is a colourless transparent region; the side of the local transparent area is downward and the other side of colourless transparent region is upwards; the glasses extend in the shape of arc. If the upper part is plated semi-permeable membrane, the working method for the glasses is not necessarily changed. The local transparent area not only avoids glare but also helps the driver see the situation of the road surface, the extending part of which prevents glare when the vehicle comes near. The colourless transparent region and the extending part help the drivers see clearly their own travel ways all the time, avoid glare, and see the panorama in front of them clearly by slightly correcting the angle of the heads.

Description

Anti-glare glasses for driving at night

The utility model belongs to a kind of driving at night and drives the antiglare glasses.

At present, driving at night is driven, and particularly leaves the urban district, the vehicle intersection, and the come headlamp of vehicle of opposite causes dizzy and does not see oneself traffic route.Even alternately beat bright headlamp separately, can not solve dizzyly at all, and it is also very inconvenient often to change the lamp source, accident appears in the place ahead can not find in time that it is very fast that eyes are sought road surface fatigue for a long time, influences safe driving.

Existing known tinted glasses, though Dai Houneng prevents dazzling the eyes of the other side's headlamp, the traffic route of oneself does not see yet simultaneously, and seems nonsensical.Though the light-sensitive sunglasses high light can variable color and prevent dizzy, night light faint, light very short and can not play a role in some residence time of glasses at all.Though, a kind of glasses of printing opacity are by different level up and down arranged now, the one, from local printing opacity to water white transparency progressively transition, the 2nd, visible light there is the printing opacity of selection and influences and see front signal lamp source clearly, same only being suitable for worn a daytime.

Task of the present utility model is will provide a kind of can prevent the dizzy of the other side's headlamp, does not influence the traffic route of seeing oneself clearly and the glasses of signal light again.

Here the utility model of being showed is finished as follows, and upper left half partly (with eyeglasses-wearing time centre of vision line be the boundary) transmitance of lens is 5～40%, and bottom right half is the clear area of transmitance＞80% partly.During use, the other side is not as there being headlamp, and head is only steeved slightly, just can as usually, see the driving prospect clearly, when the other side's vehicle headlamp is bright, as long as head levelling slightly downwards, allow headlamp be positioned at local photic zone, just can prevent to dazzle the eyes, and the traffic route of oneself can clearly be seen equally.

Further mode is, the local photic zone of the left first half is that accompanying drawing is that accompanying drawing partly has a curved handing-over seam shown in 2. with clear area partly, bottom right half partly shown in 1..Like this, the traffic route zone that can remain oneself is clearly seen, and the other side's headlamp is positioned at the anti-glare zone all the time.

Further mode is, the local photic zone of upper left half part adopts evaporation optical filtering Mo to obtain.Like this, existing manufacturing glasses need be do not changed, just various the utility model glasses such as old light, myopia, zero diopter can be obtained easily.

Describing two embodiment below in conjunction with accompanying drawing is illustrated more clearly in:

Embodiment one:

As accompanying drawing 1. portion show that partly adopt AB6 neutral gray optical glass, 2. accompanying drawing adopts colourless transparent glass shown in partly.By connecting line shape processing shown in the drawings, get up with the optics glue glued adhesion then respectively, press the glasses processing technology again, be processed into the plain glass spectacles of different shape.

Embodiment two:

Myopia eyeglass (water white) after optics cold working completion is cleaned by vacuum coating requirements, is placed on the part frame in addition of vacuum coating equipment, and the hole of part frame in addition will be processed into just like 2. shape baffle plate partly of accompanying drawing, only stay accompanying drawing 1. shown in regional hole.Carry out according to being coated with chromium layer neutral density filters technology, the transmittance when the chromium layer thickness is controlled at wavelength 550nm place is not more than 5% in the fluctuation of the transmitance of visible region about 20%.By existing Coating Materials and technology, can there be several different methods to obtain above-mentioned local light-transmissive film, just repeat no more here.This example can be suitable for being coated with of various glasses such as various zero diopters, old light equally.

Claims (3)

1, a kind of driving at night is driven anti-glare glasses, is made up of mirror holder, eyeglass, it is characterized in that being that upper left half of lens is between 5～40% in the visible region transmitance partly, and right Lower Half is the clear area of transmitance＞80%.

2, glasses according to claim 1 is characterized in that partly there is a curved handing-over seam upper left half part of lens and bottom right in the middle of the part.

3, glasses according to claim 1 is characterized in that eyeglass upper left half transmitance partly obtains by the evaporation filter coating.
