DETAILED DESCRIPTION OF THE INVENTION

(5) Eyeglasses 101 in accordance with the present invention have a main frame 102 and right and left rims 103a and 103b. A nose bridge 104 connects right and left rims 103a and 103b. Left and right temples 105a and 105b extend from the right and left rims 103a and 103b. Right and left rims 103a and 103b each have an upper rim portions 106a and 107a and a lower rim portions 106b and 107b. Lower rim portions 106b and 107b each have a groove (not shown) to hold a lens in the rim.

(6) Lower rim portions 106b and 107b are rigid while each upper rim portion 106a and 107a have flexible inner portions 108a and 108b and a rigid outer portions 109a and 109b. The flexible inner portions 108a and 108b can be moved or pulled away from the rigid outer portions 109a and 109b so that lenses 110a and 110b can be interchanged by a user without the use of tools.

(7) In use, a user can use his/her fingers to pull flexible inner portions 108a and 108b and remove a lens held in the rim. Once the lens is removed, a new lens can be inserted by pulling the flexible inner portions 108a and 108b away from the rigid outer portions 109a and 109b. Once the new lens is inserted in the frame in the groove provided in the lower rim portions 106b and 107b, flexible inner portions 108a and 108b are then released to sandwich the lens between flexible inner portions 108a and 108b and outer rigid outer portions 109a and 109b.

(8) A set of lenses having varying prescriptions can be provided to allow for a single user to change between near-sighted and far-sighted lenses or between varying degrees of near-sighted and far-sighted lenses. Further, varying degrees of near-sighted or far-sighted lenses can be provided for multiple users to use the same pair of glasses by interchanging the lenses easily and quickly.

(9) As these and other variations and combinations of the features discussed above can be utilized without departing from the disclosure as defined by the claims, the foregoing description of exemplary embodiments should be taken by way of illustration rather than by way of limitation of the disclosure as defined by the claims. It will also be understood that the provision of examples of the disclosure (as well as clauses phrased as “such as,” “e.g.”, “including” and the like) should not be interpreted as limiting the disclosure to the specific examples; rather, the examples are intended to illustrate only some of many possible aspects.
