Abstract

The utility model discloses a pair of glasses with back sight function, comprising a bracket and two lenses, wherein the bracket consists of a frame and two lens legs; a through hole is formed at the front part of each leg along the horizontal direction; a miniature telescope which is capable of rotating in the horizontal plane is arranged in each through hole; and a deep-color coating film is coated at the outer edge of each lens. The basic structure of the back sight glasses provided by the utility model is the same as the basic structures of the traditional glasses; and miniature telescopes are respectively arranged at the front parts of the legs of a pair of common glasses and deep-color coating films are coated at the outer edges of the lenses at the same time, so that a user who wears the glasses can observe the scenes which are left behind through the deep-color coating films. Through the glasses with back sight function, the basic shape and the front sight function of the original glasses are kept and the back sight effect is increased, so that the aim of preventing future troubles is achieved.

Description

Rear-viewable glasses

Technical field

The utility model belongs to glasses optical equipment technical field, particularly relates to a kind of rear-viewable glasses.

Background technology

Glasses are a kind of simple optical device that are used to correct defects of vision or protect eyes, generally include mirror holder and two eyeglasses, and mirror holder then is to be made of picture frame and two mirror legs.But traditional glasses ubiquity following point: the wearer can only see the things in the place ahead by it, can't observe scenery after one's death, therefore just might danger or accident occur because of the scenery of can't see after one's death, and this is a kind of limitation, also is a shortcoming.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of can broadening one's vision also can observe the rear-viewable glasses of scenery after one's death.

In order to achieve the above object, the rear-viewable glasses that the utility model provides comprise mirror holder and two eyeglasses, and wherein mirror holder is to be made of picture frame and two mirror legs; The anterior along continuous straight runs of described each mirror leg connects and is formed with a through hole, and a miniature telescope that can rotate in surface level is installed in each through hole; The outer ledge position of each eyeglass then is coated with dark plated film.

The eyepiece that described miniature telescope comprises lens barrel and is installed in the object lens of lens barrel interior forward end and is installed in the inner rear end of lens barrel.

Described miniature telescope is installed in the through hole on the mirror leg by two axle rods that lay respectively at its upper and lower side.

The lateral cross section of described object lens and eyepiece is rectangle, circle, ellipse or square.

The basic structure of the rear-viewable glasses that the utility model provides is identical with traditional eyewear with moulding, it is in the mirror leg front portion of common spectacles a miniature telescope to be installed respectively, plate simultaneously the dark plated film of one deck at the outer ledge position of each eyeglass, the wearer sees through dark plated film and just can observe after one's death scenery.It has not only kept the basic styling and the preceding visual function of original glasses, has also increased the backsight effect simultaneously, thereby has reached the purpose of prevention " future trouble ".

Embodiment

Below in conjunction with the drawings and specific embodiments the rear-viewable glasses that the utility model provides are elaborated.

As Fig. 1-shown in Figure 5, the rear-viewable glasses that the utility model provides comprise mirror holder and two eyeglasses 1, and wherein mirror holder is to be made of picture frame and two mirror legs 2; Described each mirror leg 2 anterior along continuous straight runs connect and are formed with a through hole 3, and a miniature telescope 4 that can rotate in surface level is installed in each through hole 3; The outer ledge position of each eyeglass 1 then is coated with dark plated film 5.

Described miniature telescope 4 comprises lens barrel 6 and the eyepiece 8 that is installed in the object lens 7 of lens barrel 6 interior forward end and is installed in lens barrel 6 inner rear ends.

Described miniature telescope 4 is installed in the through hole 3 on the mirror leg 2 by two axle rods 9 that lay respectively at its upper and lower side.

The lateral cross section of described object lens 7 and eyepiece 8 is rectangle, circle, ellipse or square.

Telescope normally is made up of lens barrel and two lens, and one of them lens is object lens, and another lens are eyepieces, and object lens and eyepiece are installed in the two ends of lens barrel respectively.When people's eyes when eyepiece sees through object lens and forwards looks, light is direct motion, this moment, its amplifications that scenery at a distance can be furthered was beneficial to its slight part of observation like this; When people's eyes when object lens see through eyepiece and forwards look, light drives in the wrong direction, and at this moment it can dwindle scenery nearby and push away far, has therefore enlarged the visual field, so that environment and the things around observing, the rear-viewable glasses that the utility model provides just are being based on a kind of principle in back and are designing.

Now the principle of work of the rear-viewable glasses that the utility model is provided is described below: under normal situation, when the wearer only need observe the things of front, can observe by uncoated part on two eyeglasses 1 and get final product, the center line of object lens 7 and eyepiece 8 will coincide with the longitudinal centre line of mirror leg 2 on this moment miniature telescope 4, and promptly miniature telescope 4 is positioned within the through hole 3 on the mirror leg 2 fully.When the wearer need observe after one's death scenery, it at first turns to the inside with the front end of hand with miniature telescope 4, the wearer looks side ways eyes slightly laterally just and can see and eyepiece 8 equal shapes and big or small bright spot in the dark plated film 5 on eyeglass 1 then, just can clearly present scenery after one's death in bright spot.

In addition, the scenery that forms in dark plated film 5 is far and near relevant with the multiple of miniature telescope 4, and multiple is big more, and scenery is more little far away more, so the fabricator can adjust as required.In addition, rear vision area is not only limited to both sides after one's death, as long as the wearer with its head slightly left or turn right movingly, its health scenery behind will come into plain view.
