These existing glasses are all adopt individual layer eyeglass above.From result of use, during viewing closer object, traditional presbyopic glasses effect is best, just when needs are seen at a distance, needs to extract glasses, if user itself or myopia, then needs to change to wear glasses, cumbersome.Owing to often will take off one's glasses, easily cause storage of glasses improper, particularly user is older, hypomnesia, finds glasses and can spend user's plenty of time often.And bi-focal or gradual multifocal distance, although convenient, have easily tired or dizzy on using.And bi-focal or gradual multifocal distance are because of eyeglass grinding technology complexity, and price is higher, and a lot of the elderly is difficult to bear.
And the Two-layer spectacle occurred in the market is generally for what have frame glasses to design, outer eyeglass all needs to disassemble usually, places up again, use cumbersome when needing.
Summary of the invention
For the problems referred to above, technical problem to be solved in the utility model is to provide a kind of double-layer lens glasses, and it mainly carries out appropriate design to no-frame glasses, thus provides a glasses being applicable to its vision condition to the elderly.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of double-layer lens glasses, comprise temple and eyeglass, its design feature is, described eyeglass comprises internal layer eyeglass and outer eyeglass, and described internal layer eyeglass is fixedly connected with temple by pile crown, is connected between described internal layer eyeglass by Jing Liang; Described outer eyeglass is arranged on outside internal layer eyeglass, and by Components installation can be turned down on pile crown; Described internal layer eyeglass is vision correction lens, and described outer eyeglass is for compensating eyeglass.
Further, the described component that turns down comprises the fixed fastener be arranged on outside pile crown and the web member be arranged on outer eyeglass, described fixed fastener is provided with the first through hole, and described web member is provided with the second through hole, is fixed between described first through hole and the second through hole by screw.By turning down component, outer eyeglass can cover outside internal layer eyeglass according to service condition, also can be folded to temple side.
Further, described internal layer eyeglass is distance vision correction eyeglass, and described outer eyeglass is that myopia compensates eyeglass, and the equivalent focal length of described internal layer eyeglass and outer eyeglass is zero diopter or myopia.
Further, outside described mirror beam, two ends are provided with projection, described projection and outer lens contacts.Because the spacing size between ectonexine eyeglass can affect the compensation effect of outer eyeglass, also the result of use of glasses will be affected, glasses can be made to keep a stable headway between outer eyeglass and internal layer eyeglass in use so arrange projection on crossbeam, ensure the result of use of glasses.
Compared with prior art, the utility model compensates outer eyeglass in tradition without frame presbyopic glasses installing additional can turn down.When user watches closer object or reads, by outer eyeglass turnover to temple both sides, only use internal layer eyeglass.Go out when user comes back, during viewing distant objects, the outer eyeglass of turnover optical compensation, outer eyeglass is for compensating internal layer eyeglass, and the equivalent focal length of double-layer lens is zero diopter or myopia.Like this, user can wear same a pair of glasses all the time, need not often take off one's glasses or change and wear near-sighted glasses, decreases the improper and possibility damaged of storage of glasses, also saves and find time of glasses.Bring convenience especially to teacher, precision optical machinery electron trade practitioner etc., when steering vehicle, wear same a pair of glasses and also can ensure safety.
