Eyeglass with removably attachable top
An eyeglass system includes interchangeable anterior aesthetics. The system includes a base frame, including a front face with a left lens orbital carrying a left lens and a right lens orbital carrying a right lens, and left and right earstems attached to the front frame. A decorative top frame includes a left annular mask with an unobstructed left opening and a right annular mask with an unobstructed right opening, configured to cover the left and right orbitals, respectively, while exposing the left and right lenses through the left and right openings. The top frame is releasably connectable to the base frame. The system may include a plurality of visually distinct top frames, each interchangeably removably connectable to a common base frame.
1. An eyeglass system comprising:
a base eyewear with a curved front frame made of a first material, the base eyewear having a thickness between an anterior surface and a posterior surface of the front frame, the front frame comprising an anterior surface and a posterior surface, the front frame including a left lens orbital carrying a left lens and a right lens orbital carrying a right lens, and left and right earstems attached to the front frame; and
a curved top frame made of a second material, the curved top frame having a thickness between an anterior surface and a posterior surface of the top frame, including a left unobstructed opening and a right unobstructed opening, configured to be positioned in front of the left and right orbitals, respectively while exposing the left and right lenses through the left and right openings, such that no part of the top frame extends in a posterior direction past the anterior surface of the front frame when the top frame is attached to the front frame; and
wherein the second material comprises a thermoplastic amorphous polyamide that is more flexible and has a lower Young's modulus than the first material;
wherein the thickness of the top frame is less than the thickness of the front frame;
wherein a curvature of the front frame corresponds to a curvature of the top frame; and
wherein the top frame is releasably connectable to the base frame by magnetic force.
2. An eyeglass system as in claim 1 , wherein the top frame comprises a posterior layer and an anterior layer.
3. An eyeglass system as in claim 2 , wherein the anterior layer has a thickness of no more than about 1 mm.
4. An eyeglass system as in claim 2 , further comprising an aesthetic enhancement carried by the anterior layer.
5. An eyeglass system as in claim 4 , wherein the posterior layer is optically transparent.
6. An eyeglass system as in claim 5 , wherein the top frame comprises a first magnet, configured to couple to a second, complementary magnet carried by the base frame.
7. An eyeglass system as in claim 6 , wherein the first magnet and the second magnets are neodymium magnets.
8. An eyeglass system as in claim 6 , wherein the base frame and the top frame are curved in a horizontal plane.
9. An eyeglass system as in claim 8 , wherein the base frame and the top frame comprise a base curve that is no more than about 4.
