Shown in Figure 1A, auxiliary eyeglasses 20 of the present utility model is connected on the primary frame removably.The maintenance structure that the primary mirror sheet is arranged on the primary frame, this primary mirror sheet may be made certain shape according to the characteristics of glasses wearer's visual impairment.

One of purposes of auxiliary lens 50 is to provide the protection that prevents sunburst and other damage eyesight factors for the glasses wearer.Therefore, auxiliary lens 50 can have color, also can comprise the material of ultraviolet ray filtering or other certain wavelength light or apply coating on it.

Auxiliary eyeglasses 20 has two auxiliary lens 50 and between two auxiliary lens 50 and the auxiliary bridge 60 that connects.From Figure 1A to Fig. 1 C, Fig. 2, Fig. 3, Fig. 4 can find out, auxiliary bridge 60 is provided with the structure that keeps auxiliary lens 50, comprises the eyeglass rivet 72 of terminal globulate.After assembling, eyeglass rivet 72 extends in the horizontal direction and passes auxiliary lens 50 beam rivet holes 52 on show.Bulb 74 has guaranteed the reliability of the connection of eyeglass 50 and auxiliary bridge 60.Before eyeglass 50 is connected to auxiliary bridge 60, just can form bulb 74,, also can in assembling process, form bulb 74 or allow its local deformation for increasing the fixing that connects.

In the assembling process of eyeglass 50 and auxiliary bridge 60, eyeglass rivet 72 is inserted into and by the mirror beam rivet hole 52 on every eyeglass 50.In illustrated embodiment, there are two eyeglass rivets to pass mirror beam rivet hole 52 on the every eyeglass.This has just guaranteed the fixing of assembling and has prevented the vertical rotation of eyeglass with respect to Jing Liang.

Because used Polyflex or memory plastics, the insertion of eyeglass rivet 72 can not damage eyeglass 50.Diameter when the profile of bulb 74 makes it indeformable is greater than hole 52.Use such material also to make bulb 74 temporarily be out of shape and can be inserted through rivet hole on the eyeglass by it.After passing rivet hole, the diameter that bulb 74 is original owing to plastic memory returns to, thus eyeglass 50 is fixed on the auxiliary bridge 60 in the stationary fit mode.The assembling back applies glue on bulb 74 or other sticking agents can improve the reliability of connection, perhaps on bulb 74, apply and be large enough to allow the pressure of its permanent strain, make bulb 74 around next-door neighbour's mirror beam rivet hole 52, be pressed on the rear surface of eyeglass 50.

So auxiliary bridge 60 provides a kind of lightweight mechanism that auxiliary lens is coupled together, and does not need complete auxiliary lens picture frame.This has not only reduced cost but also alleviated weight, and makes the outward appearance of auxiliary lens more attractive in appearance.

Auxiliary eyeglasses 20 after having assembled is integral units.The configuration design Cheng Rangqi of auxiliary lens 50 can cover two primary mirror sheets 18.The exterior contour of auxiliary lens 50 is general consistent with the exterior contour of primary mirror sheet 18.

Referring to Figure 1A, auxiliary eyeglasses 20 comprises clip 40, and this clip 40 is positioned at the top and the bottom of each eyeglass 50.As Fig. 2, shown in Figure 5, clip 40 surrounds the periphery 55 of eyeglass 50, and extends back from eyeglass 50.
