Abstract
The utility model relates to sunglasses with rearview function which comprises a glasses frame and lightless diopter glasses lens plated a light dissecting membrane. The glasses lens is a single chip light dissecting mirror or a light dissecting mirror with a protective mirror. The side of the light dissecting membrane of the light dissecting mirror protrudes toward eyes, and the scope of the curve rate radius of the side is 450 millimeters to infinity. When the sunglasses with rearview function provided by the utility model is used, eyes can be protected to be free from the harm of strong light, the rear situation can be observed while walking or riding a bike, and traffic accidents can be reduced or avoided.
Description
The utility model belongs to the sunglasses with back vision function.
Common sunglasses is made up of lens and spectacle frame, is used to protect eyes not stimulated by high light, does not have back vision function.The glasses of being introduced in patent CN85200831 and CN86202700U that back vision function is arranged all are equipped with additional reflector or are coated with the reflection horizon in the edge part of lens, and this makes mechanism's complexity, use inconveniently, and have dwindled the visual field of glasses.
The purpose of this utility model provides a kind of simple in structure, and is easy to use, the sunglasses with back vision function that the visual field does not have condiment to block.People are walking or by bike the time, not only can protect eyes not stimulated by high light, and can observe the situation of back, to reduce or to avoid traffic accident with it.
For achieving the above object, the sunglasses with back vision function that the utility model provides is to analyse light film (claiming spectro-film again) eyeglass formation by spectacle frame with being coated with.Be coated with and analyse the light film glass and be called beam divider, analyse the light film for protection and can analyse in plating and add a block protection mirror on the light face, in the case, lens is to be made of no focal power protective glass and no focal power beam divider.Protective glass and beam divider are shaped as the parallel plane glass plate or do not have the meniscus shaped lens of focal power.It is protruding in eyes that the falcate beam divider plates the face of analysing the light film, and the range of curvature radius of this face is 450 millimeters extremely infinities.Beam divider and protective glass are with coloured or flint glass or optical plastic manufacturing.
Describe below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of the present utility model, also is the eye plate figure that single beam divider constitutes.
Human eye 2 can be observed scenery in the AB scope of the place ahead by protruding no focal power falcate beam divider 1 to human eye, and scenery also be can be observed by beam divider 1 reflection in the CD scope of rear.When being infinity, this falcate beam divider radius-of-curvature becomes the parallel plane beam divider.
Fig. 2, Fig. 3 and Fig. 4 are no focal power falcate beam dividers 1 and do not have the lens figure that focal power falcate protective glass 3 constitutes.
Beam divider 1 glues together mutually with protective glass 3 among Fig. 2, the edge shimming 6 among Fig. 3 between beam divider 1 and the protective glass 3; Beam divider 1 and protective glass 3 touch in side edge among Fig. 4.
Fig. 5 and Fig. 6 are the lens figure that parallel plane beam divider 4 and parallel plane protective glass 5 constitute.
Beam divider 4 glues together mutually with protective glass 5 among Fig. 5; Edge shimming 6 among Fig. 6 between beam divider 4 and the protective glass 5.
Fig. 7 and Fig. 8 are the lens figure that no focal power falcate protective glass 3 and parallel plane beam divider 4 constitute.
The interchangeable position of protective glass among Fig. 2 to Fig. 7 and beam divider can change protective glass 3,5 into beam divider, and beam divider 1,4 changes protective glass into.
Compared with prior art, the utility model is simple in structure, does not have additional reflector, does not block on-the-spot reflection horizon, and is easy to use, good looking appearance.
