Problems solved by technology

[0002] Most of the existing patents for glasses with rear-view function have complex structures, such as the use of various designs of external rear-view mirrors, which are difficult to be accepted by the market
The simplest design is based on the rear view area formed at the outer corner of the eye by flat glasses or glasses close to flat, such as ZL91217567.2 ZL92216466.5ZL200520089379.4. You can see the scene behind you, but from the trial, the rear view scene interferes with the side and front view, and there are traffic safety hazards. At the same time, the aesthetics are not enough, and the rear view scene will be unstable when used at night

Embodiment 1

[0020] As shown in Figure 1: the glasses are made of temples (1), eyeglasses (2) and nose pads (4). The eyeglass (2) adopts the form of conjoined eyeglasses. Area outside the outer corner of the eye, i.e., the rear view area (11) adopts a flat lens, and the front view area (10) and the middle area adopt uniform arc bending, and the angle between the left and right rear view area planes is 172 degrees.

[0021] The lens (2) adopts a black-toned optical lens with a light transmittance of about 15%. The side facing the eyes does not add any film layer, but only does high-quality polishing. The refractive index of the lens (2) is more than 1.7 and the effect is better.

[0022] The temple (1) is directly connected with the lens (2). The width of the temple (1) is 18mm, and it is flush with the upper edge of the lens (2) from the root, and the width is kept at 70mm. The vertical projection on the lens (2) is located at 1.0 mm below the center line of the pupil (8) (the relationshi...

Embodiment 2

[0026] As shown in Figure 2, glasses are made of mirror legs (1), eyeglasses (2), picture frame (3) and nose pads (4), and nose pads (4) are made integrally with picture frame (3).

[0027] The mirror leg (1) design changes the eyeglass (2) in "from the root to be flush with the upper edge of the eyeglass (2)" into the eyeglass frame (3) with reference to embodiment 1, and all the other are the same.

[0028] The lens (2) adopts a brown flat lens with a light transmittance of 35%, and the side facing the eye is coated with 20nm thick TiO 2 Dielectric layer. The reason why the above ultra-thin thickness is adopted is to eliminate the color tendency.

[0029] As shown in Figure 4, the lower edge of the midline (6) of the nose bridge (5) is located at 1 mm below the center line of the pupils (8) and 1 mm below the vertex (15) of the nose pads, and the midline (6) of the nose bridge (5) ) is 12mm high, this design can effectively reduce the inner corner of the eye.

Embodiment 3

[0034] As shown in Figure 2, glasses are made of mirror legs (1), eyeglasses (2), picture frame (3) and nose pads (4), and nose pads (4) are made integrally with picture frame (3).

[0035] Eyeglass (2) adopts the eyeglass form shown in Fig. 3, adopts ellipsoid design in the eye area, and other parts still adopt flat plate design.

[0036] The eyeglass (2) is plated with a 12nm thick chromium metal film layer with a vertical reflectance of about 28% and a light transmittance of about 32% on the side facing the eyes. A 20nm ZnS dielectric film can also be sandwiched between the lens and the chrome layer, and the light reflectance and light transmittance will increase to about 40%.

[0037] Temple (1) design is the same as embodiment 2, referring to embodiment 2

[0038] The design of nose bridge (5) and nose pad (4) is the same as that of embodiment 2, see embodiment 2

[0039] Picture frame (3) eliminates interference reflection and eyeglass (2) eliminates edge elevation int...

Abstract

The present invention provides safe and simple glasses with the back sight function; the structure is of the same as the ordinary glasses. A spectacle lens is divided into a forward looking area and a back sight area at the outer canthus. The back sight is provided with a back sight reflection surface. A back sight main function area is limited under the head up line of sight during natural wearing through exploring the projection effect of a glasses leg at the back area and using a pupil safety line. So the forward looking priority principle is ensured. The back sight scene is clear and stable, the mirror type is beautiful and the application range is wide. The present invention can be used for safety warning and daily traffic safety.

Description

Technical field: [0001] The invention belongs to the field of spectacles for optical instruments, in particular, it relates to spectacles with rear vision function. Background technique: [0002] Existing glasses patents with rear-view function, most of the structures are complex, such as adopting various designs of external rear-view mirrors, which are difficult to be accepted by the market. The simplest design is based on the rear view area formed at the outer corner of the eye by flat glasses or glasses close to flat, such as ZL91217567.2 ZL92216466.5ZL200520089379.4. You can see the scene behind you, but from the trial, the rear view scene interferes with the side and front view, which poses a traffic safety hazard. At the same time, the aesthetics are not enough, and the rear view scene will be unstable when used at night. [0003] Purpose of the invention: [0004] The purpose of the present invention is to optimize the simplest form of rear-view function glasses men...
