       [0001]    This application claims the benefit of priority under 35 U.S.C. 119(e) to the filing date of U.S. provisional patent application No. 60/982,198 entitled “Air Vent Sports Eyeglass Construction” which was filed Oct. 24, 2007, and is incorporated herein by reference. 
     
    
     FIELD OF INVENTION 
       [0002]    This present invention relates generally to eyewear. In particular, it relates to eyewear for use in sports and the like; and more particularly to eyewear which contains a removable sealing member. 
       BACKGROUND OF THE INVENTION 
       [0003]    Usually sports eyeglasses containing an inner removable sealing member where the inner removable sealing member is designed to be attached to the back of the main eyeglasses frame. In particular, the inner sealing member is designed to contain clips or the likes that attaches to the back of the main eyeglasses frame. More particularly, the clips of the inner sealing member are designed to be snapped into grooves formed in the back of the main eyeglasses frame. 
         [0004]    Typically, where the side to which the inner removable sealing member attaches to the back side of the main eyeglasses frame (the side to which the lens is concaved) is considered as the front side of the inner removable sealing member, the back side of the inner removable sealing member is typically coupled with soft substances like foam or sponges so the inner removable sealing member when worn can wrap around the user&#39;s face and sufficiently seal against the skin of the face of the wearer from dusts and the likes. 
         [0005]    In this typical construction, the combined the thickness of the side profile (not including the eyeglasses temple) of the entire eyeglasses construction (the frame, the inner sealing member and the foam or sponges) reaches 4 millimeter-12 millimeter, measuring from the center of the lens (as in the context of side profile) to the point of contact between the skin and the soft substances when the eyeglasses is worn. 
         [0006]    There are several disadvantages to this typical construction. In particular, because the extended thickness of the side profile, the center of gravity of the entire eyeglasses (the main eyeglasses frame, the inner sealing member, and the sponges or foam) construction typically rests far from the eyes of the wearer when worn. Consequently, it causes the entire eyeglasses construction to shift forward when worn. This is undesirable because when the center of gravity rests far from the eyes of the wearer, it has a tendency to cause the eyeglasses to shift forward when worn and as a result the view to the side of the wearer is severely reduced. In addition, the eyeglasses is more likely to shift and eventually fallen off from the wearer when in use. Moreover, gaps are often created between the wearer&#39;s skin and the soft substances such as foam or sponge as the entire eyeglasses construction shifts forward during use, defeating the purpose of preventing dusts from coming into contact with the eyes of the wearer. Furthermore, with such extended distance, even blank lens can cause plus or minus degree. 
       OBJECT OF THE INVENTION 
       [0007]    It is an object of this invention to provide an eyeglasses construction wherein the eyeglasses containing removable sealing unit designed to fit in place between the eyeglasses and a wearer&#39;s face wherein the side profile of the eyeglasses construction is reduced by at least 1 mm to 14 mm as compare to the other eyeglasses construction in the market utilizing an overlapping profile design incorporated into the removable sealing unit wherein the overlapping profile attaches its extended profile to the eyeglasses. 
         [0008]    It is an object of this invention to provide an eyeglasses construction wherein eyeglasses containing removable sealing unit designed to fit in place between the eyeglasses and a wearer&#39;s face wherein the center of gravity of the eyeglasses construction is close in proximity to the wearer&#39;s eyes wherein the eyeglasses is not likely to shift and fallen off from the wearer when in use. 
       SUMMARY OF INVENTION 
       [0009]    The present invention involves a sport eyeglasses frame where the inner sealing member is designed to contain an overlapping profile where the overlapping profile acts as attachment means such as clips, connectors, fasteners, and joinders to attach the inner removable sealing member to the main eyeglasses frame where the clips are designed to snap into the grooves formed on the front side of the main eyeglasses frame thus reducing the side profile (not including the temple of the eyeglasses) of the entire eye glass construction (the main eyeglasses frame, the inner sealing member, and the soft substances such as foam or sponge) by 1 millimeter to 5 millimeter. 
         [0010]    In one embodiment the over lapping profile of the inner sealing member is acting as attachment means such as clips where grooves are formed on the front side of the eyeglasses frame over the bridge area of the main eyeglasses frame and the overlapping profile snaps into the grooves. 
         [0011]    Another embodiment is for the overlapping profile of inner sealing member to act as holding means where grooves are formed on the outside of the temple of the eyeglasses frame and the overlapping profile acting as clips snap into the grooves formed on the outside of the temple of the eyeglasses frame. In this particular embodiment, the inside of the temple of the eyeglasses frame is the side to which that contacts the skin of the wearer and the outside of the temple of the eyeglasses frame is the opposite side to the inside of the temple of the eyeglasses frame. 
         [0012]    In another embodiment the overlapping profile of the inner sealing member acts as attachment means over the main eyeglasses frame and the overlapping profile is secured to the main eyeglasses frame with screws or the likes. 
         [0013]    In yet another embodiment the over lapping profile of the inner sealing member is acting as attachment means such as clips where grooved are formed on the front side of the main eyeglasses frame and over the top of lens of the main eyeglasses frame and the overlapping profile snaps into the grooves. 
         [0014]    In yet another embodiment the overlapping profile of the inner sealing member is acting as attachment means such as clips where grooves are formed on the front side of the main eyeglasses frame and under the lens of the main eyeglasses frame and the overlapping profile snaps into the grooves. 
         [0015]    In another embodiment the overlapping profile of the inner sealing member acts as attachment means and attach around the entire eyeglasses frame. 
         [0016]    In yet another embodiment the inner sealing member is constructed in such way where the back side of the inner sealing member contains equally spaced risers where the attaching soft substances like foams or sponges are designed to contain equally spaced grooves to match the risers so that when the foam or sponge are attached to the back of the inner sealing member the riser acts as support and prevent the foam or sponge from collapsing after extended use. 
         [0017]    In another embodiment the soft substance attached to the back of the inner sealing member is not air permeable. 
         [0018]    In another embodiment the inner sealing member is made with durable plastic foam material made of ethylene vinyl acetate resin. Likewise, the inner sealing member can also be manufactured using materials such as plastic, rubber, or silicon. 
         [0019]    In yet another embodiment, the inner sealing member also contains optical lens and the optical lens are removable. 
         [0020]    In a preferred embodiment, the grooves formed on the outside of the eyeglasses frame for the overlapping profile of the inner sealing member to snap into additional function as air vents. In particular, the frame contains grooves formed on the outside of the main eyeglasses frame and around the lens where the grooves additional act as air vents, where air permeable material such as sponge, air permeable textile, and or wire mesh is placed inside the grooves, and where through holes are formed on the main eyeglasses frame inside the grooves, and where the inner sealing member also contains matching through holes when the inner sealing member is attached to the main eyeglasses frame. In this construction, air may pass from the outside of the eyeglasses through the air vents, the through holes, and the soft substances to the skin of the face. In this embodiment, the grooves are designed to be large enough where when overlapping profile snaps into the grooves there is sufficient room left in the grooves for the air to pass through. 
         [0021]    In yet another embodiment, the through holes are placed around the inside edges of the corresponding lens opening of the inner sealing member. In this particular embodiment, the inner sealing member does not contain optical lens and only the main frame eyeglasses contains optical lens.
