Description

Glasses meet at night

The glasses that meet at night that the utility model relates to belong to the automobilist and use the safeguard protection articles for use.

On daytime, the driver drives generally can wear sunglasses to weaken dazzling high light under burning sun.And driving at night can often run into and the meeting situation of head-on sending a car, according to public security, traffic relevant department statistics, when meeting at night, because next vehicle light too strong (brightness can reach 15000 luxs) is sailed on the opposite, cause the temporary transient ablepsia of driver, can't see the vehicle front what happens clearly, it is a key factor of vehicle generation traffic hazard, accident takes place thus occupy very big ratio in traffic hazard, it is one sided that obvious driving at night head driver time wear dark glasses reduces meeting strong light illumination.

The utility model purpose is to provide a kind of glasses that meet at night, and can eliminating when meeting at night of using sailed the vehicle that comes by the opposite and penetrated the light that comes and cause driver's visual fatigue and temporary transient ablepsia to be caused accident hidden danger, thus the minimizing traffic hazard.

The technical scheme that adopts that achieves the above object is: this glasses that meet at night, comprise that picture frame and the eyeglass that is inlaid on the picture frame (comprise glass mirror, the CR-39 resin sheet), it is characterized in that: on the eyeglass above the eyes optical axis, also be bonded with the viscose paper that transmittance is lower than eyeglass; Or be bonded with the glass sheet that transmittance is lower than eyeglass; Or this eyeglass is gone up down less than the eyeglass of eyeglass by 2/3 part eyeglass and about 1/3 part transmittance and is inlaid in jointly after the butt joint on the picture frame and constitutes; Or synthetic or dyeing forms the zone of two different transmittances by plated film or technology on a lens.Or on eyeglass, form a kind of zone of transmittance by dyeing.Or on eyeglass, form part grating or polarization or all grating or polarization by any technology.

The embodiment that provides below in conjunction with accompanying drawing further describes.With reference to Fig. 1, Fig. 2, originally meet at night glasses profile and common spectacles roughly the same, comprise known, public picture frame (1) and be inlaid in the normal transparent eyeglass (2) of picture frame (1) that wherein said picture frame (1) comprises parts such as picture frame, mirror leg.And characteristics of the present utility model are to consider the car light light intensity decreasing factor that must be sent a car in the opposite when meeting at night, also considered the no meeting situation situation of normally going out walking in the night simultaneously, existing Windproof glasses, sunglasses are comprehensively improved design, promptly utilize sunglasses optical filtering characteristics and don't influence driving at night driver eye purpose visibility.The scheme that realizes above-mentioned thought has following several form.

1. referring to Fig. 3, it is on the basis of normal transparent eyeglass (2), at about 1/3 place, eyeglass (2) top is that place, eyes optical axis top is pasted with the viscose paper (3) of transmittance less than eyeglass (2), this viscose paper (3) can be selected commercially available coloured cellophane paper with 1～5% coloring ion for use, color is not limit, make the driver can not produce temporary transient ablepsia as long as select certain illumination that can filter the dipped headlights photograph for use, simultaneously can inspect the road surface situation again is advisable, the zone that on whole eyeglass, is divided into two different transmittances like this, the driver can not utilize 2/3 place's forward sight below the higher eyeglass of transmittance (2) when had meeting daytime to night, and when have the meeting situation night, as long as the driver bows a little and then can utilize the higher 1/3 minute surface area forward sight that promptly is pasted with viscose paper (3) of transmittance.

2. referring to Fig. 4, in like manner eyeglass (2) is divided into two zones that transmittance is different with shown in Figure 3, difference only is that 1～5% coloring ion eyeglass (4) that promptly has that is lower than eyeglass (2) with transmittance replaces viscose paper (3), and effect is identical, also can adopt bonding way.

3. referring to Fig. 5, the zone of in like manner public eyeglass (2) being made two different transmittances with Fig. 3, Fig. 4, wherein eyeglass is embedded on the picture frame (1) jointly and constitutes after the upper and lower butt joint of eyeglass (5) less than eyeglass (2) by common eyeglass of 2/3 part (2) and 1/3 part transmittance, and wherein eyeglass (5) also selects for use the eyeglass with 1～5% coloring ion to make.

4. referring to Fig. 5, shown in Figure 5ly can also represent another kind of form, promptly on a lens that is inlaid on the picture frame (1), by about allocation proportion of 1/3,2/3, by making with synthetic method on optical coating or the optics manufacture craft or two zones of two different transmittances of dyed formation, wherein go up 1/3 area and be used to meet at night for the low-transmittance minute surface, wherein down 2/3 area be daytime or night cruising usefulness.

5. referring to Fig. 6, Fig. 7, Fig. 8, it is the mutation of the glasses that meet at night of Fig. 4 form, be that coloring ion glass mirror (4) is not to be bonded on the eyeglass (2), but the imitation steelworker picture frame (1) on has constituted collapsible meet at night glasses with glass sheet (4) by movable being connected of machinery with the folding glasses form.Mechanical connecting structure is specifically seen shown in Figure 7, it include one with the web joint (6) of picture frame (1) with screw or riveted joint, what be connected with web joint (6) has a framework (7), be fixed with two " [" type muscle (10) (11) respectively by two long spiro nails (8) (9) in the framework (7), traverse and also have a square shaft (12) in the framework (7), also have a spring leaf (13) in the framework (7), bonding or screw is connected on the square shaft (12) with eyeglass (4).Serves as that supporting is rotated 90 degree backs and is shape shown in Figure 8 by spring leaf (13) elastic force fixed position when the people then makes square shaft (12) when breaking index glass sheet (4) off with the fingers and thumb with framework (7), and during the driving at night meeting, as long as can filter meeting strong light with breaking off with the fingers and thumb under the eyeglass (4) when 90 degree make it parallel with eyeglass (2).

6. use dyestuff that eyeglass is dyed the zone with a kind of transmittance referring to Fig. 9, the decay high light of using.

7. use any technology on eyeglass, to form part grating or whole grating referring to figure (1) or figure (9).

8. use any technology on eyeglass, to form partial polarization or whole polarization referring to figure (1) or figure (9).

Need to prove normal transparent eyeglass (2), coloured glass paper (3), painted lenses (4), painted lenses (5) or coated layer or dyeing etc., and collapsible mechanical realization, structure is of a great variety, differs from one another, but non-the application problem to be solved.And the glasses that the eyeglass that passes through two kinds of different transmittances constitutes, the opposite of decaying sails the high light of vehicle to cause the temporary transient ablepsia of department's car, and increasing the preceding visual function that meets at night is the application's theme.

The utility model major technique characteristics are; according to optical principle; on original optometric technology basis; on the eyeglass (2) greater than 2/3 place in picture frame (1) be optical axis top approximately bonding the or butt joint in 10mm position or mechanical connection coloured glass paper or coloured glass sheet or dyeing to form two transmittance zoness of different; and utilize eye both view angle adjustment (0.1～2 degree between) function; or form a kind of zone (9) of transmittance by dyeing; with the decay high light; the needed safety guard of driver---glasses meet at night when having formed the driving at night meeting; utilization can avoid driving at night the time sail the light of vehicle that the driver is produced traffic hazard that temporary transient ablepsia is sent out by the opposite, increased the preceding visual function when meeting at night.
