The purpose of this utility model provides a kind of Multifunction anti-glare glasses, and it can be decayed high light more than 80%, and it is unaffected to just look at road surface brightness, especially under highway and no street lamp situation, wears not tired for a long time.

The purpose of this utility model is achieved in that

A kind of Multifunction anti-glare glasses, it comprises: mirror holder, eyeglass, the local light-blocking region in one place is arranged respectively on the left and right eyeglass, it is characterized in that: eyeglass is provided with dye layer, coating or the coating of three different transmitances from bottom to top, the bottom is colourless, and the middle part is yellow, and top is dark, the transmittance of eyeglass integral body from bottom to top constantly reduces, and its zone of transition is continuous gradation or sudden change; The transmittance of described local light-blocking region≤45% and＞1%, area 〉=20 square millimeter and less than dark district, top, distance≤70 between the two local light-blocking regions millimeter; Described top darker regions can be bottle green, buff, peony, Dark grey.

The country that the left rudder wheel travels, the position of local light-blocking region is above center of lens on the left eyeglass; The country that the right standard rudder wheel travels, the position of local light-blocking region is above center of lens on the right eyeglass.Described local light-blocking region is the spectro-film that is coated with medium and metal, for the absorbing film of dyeing, spraying, stickup, perhaps is translucent frosted layer, liquid crystal device, photoelectricity variable color film perhaps.The surface of eyeglass also is coated with stiffened or antireflection optical medium rete, and its number of plies is one or more layers.

The utility model has following advantage and good effect:

It reaches further quantification to transmittance and its spacing of local light-blocking region, stops the high light ability and reduce sense of depression to reach goodization, and the film that is in the light adds protective film, and the anticorrosive and life-span improves greatly, and the colourity of eyeglass distributes and also reaches better layout; Be suitable for automobile, Motor-cyclist and cyclist and protect high light night.

Fig. 1 is a schematic perspective view of the present utility model.

Describe the utility model in detail below in conjunction with drawings and Examples.

Be illustrated in figure 1 as a kind of better embodiment of the present utility model, form by eyeglass 1 and mirror holder 2, eyeglass is selected the CR-39 resin that is added with ultraviolet absorber for use, keep its underpart 3 colourless, middle part 4 is pale yellow, and top 5 dark colors are cleaned eyeglass then, and after drying, dye the zone on its top about 1/3 dark green or dark-grey once more; After the drying its eyeglass is put into vacuum coating equipment once more, with its surperficial evaporation double-layer reflection reducing coating, and at left center of lens upper section, the part of taking back above right eyeglass is local light-blocking region 6 with the film that is in the light that vacuum coating equipment is coated with two transmitance＜10% again, adds on the film that is in the light to be coated with one deck medium protective layer; Two are in the light the area of film greater than 20 square millimeters, and shape can be any, and this example is an ellipse garden shape, two be in the light film pack into behind the mirror holder apart from d≤70 millimeter.

Principle of the present utility model is: when human eye is subjected to the stimulation of car light high light, pupil is punctured into 1 millimeter or littler automatically by normal 4 millimeter, make light-inletting quantity reduce to original 1/16 or still less, behind the meeting since pupil have little time to recover, light-inletting quantity is die-offed, similar blind phenomenon of looking occurs, do not see the road surface; The utility model accomplishes the light-blocking region transmittance first＜8%, make the car light high light to the stimulation of eyes less than the stimulation of self car light to eyes, the human eye pupil is constant before and after the meeting, light-inletting quantity does not subtract, see that road surface brightness is unaffected naturally, it is too low to have solved the mirror that always the is in the light efficient that is in the light first, and pupil is excited to shrink this difficult problem of blurring of vision behind the meeting.

Consider most driver Dai Jinghou eyes all down, it is colourless that the utility model is made the bottom to eyeglass, middle part yellow, top dark color; The driver sees and is still colourlessly nearby, can not produce illusion or see the sensation that yellow causes eyes to ache for a long time; Yellow spectrum road pavement in the middle part of the driver utilizes when seeing at a distance has to increase regards usefulness as, especially the moon, rain, greasy weather, the distance of distinct vision greatly improves, and dark color is made on top, can play the effect of traditional sunglasses or light-sensitive glasses at least at local light-blocking region is accidental when departing from intense light source stop portions high light; Simultaneously, dark district is more approaching with the color of local light blocking layer, can not cause local light blocking layer and colour of lens contrast too big, influences attractive in appearance.

Distance between two local light-blocking regions is made＜70 millimeters, be in order to utilize closing automatically of people to look like physiological function, consider that the average interpupillary distance of world population is 63 millimeters, most of people wear this mirror can make two parts film that is in the light produce and to close picture, alleviate right light-blocking region sense of depression of rocking before eyes, and block sight line as few as possible.

Be coated with at lens surface and add dura mater, strengthened the serviceable life of resins such as CR-39 greatly, plate antireflecting film and can make light reduce by about 7% loss, and reduce, image quality is obviously improved from the interference of back dazzle to eyes.

In addition, when local light-blocking region was spectro-film, spectro-film was coated with medium protective layer, and when local light-blocking region was liquid crystal or photoelectricity variable color film, two light-blocking regions can be made the dynamic type of following the tracks of the high light incoming position; The material of eyeglass can be the CR-39 resin, PC sheet or glass sheet; Eyeglass is made transmittance＜10% of ultraviolet light,long wave and UV-B, can obtain better effect.
