Description

The multi-functional rear-view eyeglass of safe driving

The utility model relates to a kind of glasses that protect order and have back vision function, belongs to the optometric technology field.

Safety goggles of the prior art, comparatively common with sunglasses, light-sensitive glasses etc., they have tangible attenuation to high light, thorn sight etc., but can not satisfy people's requirement, Chinese patent 91212649.3 provides a kind of safe driving lens, the essence of this lens is multicoating on common optics funeral broker lens, the SnO that plated underlayer 150～300nm is thick ₂Coatings, the thick MgF of top layer plating 80～120nm ₂Coatings.Glasses by this lens is made can improve vision visibility at night, overcast and rainy etc., and the thorn sight that can decay again is suitable for motor vehicle, bicycle driver use.But this safe driving glasses do not have back vision function.And in many occasions of daily life, as traffic, military affairs, tourism etc., people often need to broaden one's vision, so that prediction is looked back, enlarge monitoring range.At present there are not glasses to appear on the market with back vision function.Chinese patent 94202973.9 discloses a kind of rear-view eyeglass, this glasses are on the basis of traditional eyewear, respectively install a cover and have an optical system of back vision function in two mirror pin, this system is by cylindrical cavity always and be loaded on negative lens group, the positive lens groups in the cavity and turn to the prism group to form.There is the contradiction between cavity cross section and the mirror pin size in this rear-view eyeglass, thereby rear vision area is subjected to certain restriction, and sharpness is relatively poor; Aspect in addition because the backsight optical system is to be fixedly mounted on the mirror pin, when in reading, write or see that TV etc. does not need under the situation of backsight, because the effect of backsight optical system, scenery can be reflected in the eye behind, makes people's dispersion attention, inefficiency.

The purpose of this utility model is to overcome the weak point of above-mentioned rear-view eyeglass, adopt MULTILAYER COMPOSITE plated film safe driving lens, design a kind of simple in structure, rear vision area is big, sharpness is high, and the movable rotation of its rearview mirror can change the multi-functional rear-view eyeglass of safe driving of rearview mirror use location.

The utility model comprises lens, lens framework, mirror pin, and lens adopts MULTILAYER COMPOSITE coating glasses sheet, promptly by ordinary optical funeral broker lens through plated underlayer SnO ₂Film and top layer plating MgF ₂Film is formed, SnO ₂Thickness is 150～300nm, MgF ₂Thickness is 80～120nm, it is characterized by: a rearview mirror respectively is set in the left of left eyeglass lens right-hand inboard inboard and the right eye eyeglass, rearview mirror is made up of glass prismatic glasses and backsight picture frame, rearview mirror has a cantilever, this cantilever is connected through the hinge and is installed on the lens framework, rearview mirror can rotate 80～120 degree to closing the position with the mirror hem facing from fitting in the lens position by the movable rotation of cantilever.

The utility model has following characteristics:

1, on the basis of traditional eyewear, increased backsight optical system---the rearview mirror of an exquisiteness, still can normally face the place ahead after wearing, the function that keeps original myopia correction, long sight or plain glass spectacles need not turned round rotary head, and eyeball rotates slightly just and can come into plain view to behind scenery, rear vision area is big, clear patterns does not have deformity, becomes erect image.

2, the rearview mirror design is unique, movable rotation.When as go out to execute the task or field work need enable back vision function the time, can be transferred to rearview mirror and lens applying position, as shown in Figure 1; When in office operation, when reading a book, write, seeing that TV etc. does not need backsight, can be transferred to rearview mirror with the mirror hem facing and close the position, as shown in Figure 2, at this moment rearview mirror just can not reflex to behind scenery in the eye, makes notice concentrate the efficient height.

3, lens adopts MULTILAYER COMPOSITE plated film safe driving lens, have various harm rays such as good decay ultraviolet ray and thorn sight, dazzling light ability, have high-visibility and haze-penetrating capability, can prevent that ultraviolet ray is to the injury of eyes and avoid burning sun or the interference of opposite car light high light.Be seen as natural light outward,,, can not see wearer's eyes, have no side effect owing to special reflex from the opposite, effective, be a kind of comparatively ideal safe driving and anti-high light field work protective spectacles.

The utility model, owing to have These characteristics, applied range:

1, adapting to various automobile driver daytime, night, the moon, rainy day or use in strong thorn, dazzling light down train especially, is the product of safe driving indispensability.

2, the special usefulness that adapts to military affairs, public security, secret service, security personnel's antitracking.

3, the adaptation traffic police looks forward to the prospect under various weather and looks back, and enlarges monitoring range, accurately judges commander's usefulness.

4, adapt to development and production microwave electron equipment, microwave experiment, broadcasting, television transmitting station, radar, called station, hospital's physiotherapy, magnetic therapy, all have the usefulness that the staff protects order under the electromagnetic radiation environment at colour TV, monitor, microcomputer terminal, computer typewriter, video tape recorder etc. for a long time.

5, the oil, the forest worker that adapt to all operations in the open air, or the staff protects the usefulness of eyes under the environment such as snowfield, desert, ocean.

6, adaptation compartment ticket seller goes out by bike and even goes across the road and various sightseeing traveler broadens one's vision, and prevents or reduce the usefulness of traffic hazard and injury accident early.
