ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an eyeglasses assembly, more particularly to an eyeglasses assembly that includes a removable auxiliary eyeglasses unit.
2. Description of the Related Art
Eyeglasses, such as eyesight correcting eyeglasses or sun-shading eyeglasses, are currently in wide use. However, conventional eyeglasses only have one function, which is very inconvenient for users. For example, some people need eyesight correcting eyeglasses for vision correcting purposes. Because eyesight correcting eyeglasses are seldom capable of providing sun-shading functions, they are replaced by sun-shading eyeglasses when the user is outdoors. On the other hand, sun-shading eyeglasses generally lack vision correcting functions, thereby resulting in a great deal of inconvenience to users.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide an eyeglasses assembly that includes a removable auxiliary eyeglasses unit to enable the eyeglasses assembly to possess both eyesight correcting and sun-shading functions in order to overcome the aforesaid drawback.
According to the present invention, an eyeglasses assembly includes a main lens frame, a pair of primary lenses and an auxiliary eyeglasses unit. The main lens frame includes an adjacent pair of lens-holding rims, each of which has an inner rim portion adjacent to the other one of the lens-holding rims and formed with a rearwardly extending frame-retaining hook. The main lens frame further includes a bridge that interconnects the lens-holding rims and that is provided with a rearwardly extending stud. Each of the pair of primary lenses is mounted in a respective one of the lens-holding rims. The auxiliary eyeglasses unit includes an auxiliary lens frame that is generally inverted-U in shape and that has a pair of generally upright lens-holding arm portions and a connecting portion interconnecting upper ends of the lens-holding arm portions, and a pair of auxiliary lenses that are mounted respectively on the lens-holding arm portions. The auxiliary lens frame is mounted removably on the main lens frame such that each of the lens-holding arm portions engages a corresponding one of the frame-retaining hooks and such that the connecting portion engages the stud to dispose removably the auxiliary lenses behind the primary lenses, respectively.
