Abstract
The utility model provides a pair of Polaroid bifocal glasses comprising a frame and Polaroid polarizers installed on the frame. The Polaroid bifocal glasses are characterized in that through holes are formed on the lower parts of the Polaroid polarizers; presbyopic lenses are embedded in the through holes; and the Polaroid polarizers are fastened with the presbyopic lenses by structure of grooves and tenons. The height of the tenons and the depth of the grooves are both 0.5MM. According to Polaroid bifocal glasses, the through holes are formed on the lower parts of the original Polaroid polarizers, and then the presbyopic lenses are installed so that bifocal use of the Polaroid polarizers and the presbyopic lenses can be realized. Meanwhile, by adopting the technology that original gluewater or high temperature adhesion is replaced by a clamping structure embedded by the tenons and the grooves, seamless integration of two lenses can be realized and the defects that originally adopted gluewater is harmful to a human body and the fastness is not high enough can be overcome.
Description
Technical field
The utility model relates to optical field, particularly a kind of Bao Lilai bifocals.
Background technology
Traditional bifocals mostly is to adopt and the methods such as glue or high temperature link together different eyeglasses, be that 200720107857.9 utility model discloses a kind of adolescent myopia control glasses such as China Patent No., comprise spectacle frame, be installed in the large eyeglass of myopia on the spectacle frame, the outside, below of described large eyeglass is provided with merges one or the protruding concave-sphere of splicing all-in-one-piece, and the large eyeglass inboard corresponding with protruding concave-sphere is provided with merges one or splicing all-in-one-piece arc prism.Adopt above-mentioned various structure, the shortcoming such as it is unstable all to have quality, not easy to operate.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of without glue, need not pass through high temperature adhesives, also is not screwed, and directly passes through the seamless combination technology with two material differences, the lens combination Bao Lilai bifocals together that camber is different.
The utility model is achieved in that a kind of Bao Lilai bifocals, comprise mirror holder and the Bao Lilai polaroid that is installed on the mirror holder, it is characterized in that: the bottom of described Bao Lilai polaroid is provided with through hole, be embedded with the presbyopic sheet in the described through hole, be fastened by groove and tenon structure between described Bao Lilai polaroid and the presbyopic sheet.
The bore periphery inwall of described Bao Lilai polaroid is provided with a tenon, and the peripheral outer wall of described presbyopic sheet is provided with a suitable groove with it.
The height of described tenon and the degree of depth of groove are 0.5MM.
The utility model has the advantage of: the bottom at original Bao Lilai polaroid is provided with through hole, then install the presbyopic sheet, the two light that can realize Bao Lilai polaroid and presbyopic lens use, adopt simultaneously trip and the clamping structure of groove phase embedding to replace the technology of original glue or high temperature adhesives, both can realize the seamless combination of two kinds of eyeglasses, it is harmful to overcome again original employing glue, and the not high enough defective of firmness.
