[0001] The utility model relates to the technical field of glasses, in particular to a pair of glare-proof nighttime driving glasses. Background Art

[0002] When driving at night, the driver is often exposed to strong light from oncoming vehicles or other extremely strong light sources entering his eyes, making it impossible for him to see the road conditions clearly and causing danger.

[0003] Currently, night driving glasses are achieved by using yellow filter lenses or polarization to remove some of the more glaring light.

[0004] Since it is necessary to take into account the visibility of low light at night, this method will still retain dazzling light that is enough to dazzle the driver, and cannot fundamentally solve the problem of dazzle caused by strong light entering the eyes and thus unclear road conditions.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] As described in the background art, in the prior art, due to the need to take into account the visibility of weak light at night, this method still retains dazzling light that is enough to dazzle the driver, and cannot fundamentally solve the problem of glare caused by strong light entering the eyes and thus unclear road conditions.

[0024] Based on this, the utility model provides an anti-glare night driving glasses. Different from traditional driving glasses, the lenses of the utility model include a lens body, which includes an objective lens, a reflecting prism and an eyepiece from the outside to the inside. The reflecting prism includes at least two pieces. The objective lens and the eyepiece are arranged non-parallel, and the light is reflected by the reflecting prism. A photochromic mirror is arranged between adjacent reflecting prisms. The color depth of the photochromic mirror is different under different brightness of light. The real image area with high brightness has a dark color, and the color change of the part with low brightness is not obvious. Therefore, the photochromic mirror can modulate the brightness of the real image to make it more uniform and significantly reduce the brightness of the strong light part, so that the observer will see the effect of greatly reducing the brightness of the strong light part of the object in front when observing from the eyepiece.

[0025] The following is combined with specific Figure 1-2 A preferred embodiment of the utility model of anti-glare night driving glasses is described in detail.

[0026] like Figure 1 As shown, it is a structural schematic diagram of a preferred embodiment of the utility model anti-glare night driving glasses. The anti-glare night driving glasses include a frame 1, a strap 2 and a lens 3. The strap 2 is cross-mounted on one side of the frame 1 and is fixedly connected to the frame 1. The lens 3 is snap-fitted and mounted in the middle of the frame 1. That is, the glasses of this embodiment are head-mounted glasses, thereby reducing the pressure on the bridge of the nose when ordinary glasses are worn.

[0027] like Figure 2As shown, the lens 3 includes a sheet body, which includes an objective lens 33, a reflecting prism 34 and an eyepiece 35 from the outside to the inside. The objective lens 33 and the eyepiece 35 are arranged non-parallel, and reflect light through the reflecting prism 34. The reflecting prism 34 includes at least two pieces. In this embodiment, it is preferred to include four pieces. Every two reflecting prisms 34 form a group. A photochromic mirror 36 is provided between the two reflecting prisms 34 in each group. The photochromic mirror 36 is located on the reflected light of the two reflecting prisms 34 in each group.

[0028] The sheet body of this embodiment is U-shaped, specifically including a first light channel 31 and a second light channel 32. The first light channel 31 and the second light channel 32 are both bent, and the first light channel 31 and the second light channel 32 extend to the bottom along the two side walls of the sheet body.

[0029] In this embodiment, both the first light channel 31 and the second light channel 32 have an objective lens 33 and two eyepieces 35, and the reflecting prisms 34 include four pieces, two of which are provided on the first light channel 31. One of the reflecting prisms 34 on the first light channel 31 is located on the extension line of the central axis of the objective lens 33, and the other reflecting prism 34 on the first light channel 31 is located on the extension line of the central axis of the eyepiece 35.

[0030] The second light channel 32 has two pieces. The bending of the first light channel 31 and the bending of the second light channel 32 are both achieved by two reflecting prisms 34. One of the reflecting prisms 34 on the second light channel 32 is located on the extension line of the central axis of the objective lens 33, and the other reflecting prism 34 on the second light channel 32 is located on the extension line of the central axis of the eyepiece 35.

[0031] The imaging principle of the anti-glare night driving glasses of this embodiment is similar to the imaging principle of a telescope, where light from a distant object forms a real image on the image plane through the objective lens 33, and forms an image in the observer's eyes through the eyepiece 35. Objects at night can form a real image through the objective lens 33 of the anti-glare night driving glasses, and at the same time, due to the effect of strong light such as the high beam of an oncoming car, the imaging area corresponding to the formed real image has extremely high brightness relative to other parts (such as the area imaged by the high beam of a car).

[0032] A photochromic mirror 36 is arranged at the rear image plane of the objective lens 33. Since the color depth of the photochromic mirror 36 is different under different brightness of light, the real image area with high brightness is dark in color, and the color change of the part with low brightness is not obvious, the photochromic mirror 36 can modulate the brightness of the real image to make it more uniform and significantly reduce the brightness of the strong light part, so that the observer will see the effect of greatly reducing the brightness of the strong light part of the object in front when observing through the eyepiece 35.

[0033] That is, a photochromic mirror 36 is added to the imaging position between the objective lens 33 and the eyepiece 35 of the anti-glare night driving glasses of this embodiment, so that the strong light part becomes soft after modulation, which is beneficial for the wearer to observe, improves the comfort and safety of night driving, and thus reduces the occurrence of night accidents.

[0034] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
