Attachable/detachable covering lens
View Patent ↗An attachable/detachable covering lens for covering eyeglass lenses is disclosed. A transparent optical material is suitably shaped to cover at least a portion of an eyeglass lens. The transparent optical material is coupled to the eyeglass lens by adhering means. The adhering means may comprise a viscosity of the transparent optical material. Embodiments of the disclosure provide mechanisms to easily provide attachable/detachable temporary lenses such as a sun-shield, temporary eyesight correction to the prescription lenses for applications such as reading, watching TV, or 3-D movie viewing. Embodiments of the disclosure also provide mechanisms for providing an easily attachable/detachable temporary prescription lens over special purpose glasses.
1. An attachable/detachable lens for covering an eyeglass lens, comprising:
a transparent optical material comprising temporary eyesight correction suitably shaped to cover at least a portion of a prescription eyeglass lens; and
adhering means for coupling the transparent optical material to the prescription eyeglass lens, the adhering means comprising an inherent viscosity of the transparent optical material.
2. The attachable/detachable lens for covering an eyeglass lens according to claim 1 , wherein:
the transparent optical material comprises a tab detached from the prescription eyeglass lens; and
the tab is suitably shaped to be used for detaching the transparent optical material from the prescription eyeglass lens.
3. The attachable/detachable lens for covering an eyeglass lens according to claim 1 , wherein the temporary eyesight correction comprises a reading correction.
4. A lens assembly, comprising:
a frame comprising prescription eyeglass lenses coupled to one another by means of a bridge piece; and
covering lens means detachably coupled to each of the prescription eyeglass lenses by inherent viscosity of the covering lens means, and comprising a transparent optical material comprising temporary eyesight correction suitably shaped to cover at least a portion of the prescription eyeglass lenses.
5. The lens assembly according to claim 4 , wherein the temporary eyesight correction comprises a reading correction.
6. A method for covering eyeglass lenses, the method comprising:
providing a prescription eyeglass lens;
providing an attachable/detachable covering lens comprising a transparent optical material comprising temporary eyesight correction suitably shaped to cover at least a portion of the prescription eyeglass lens; and
adhering the attachable/detachable covering lens to the prescription eyeglass lens by inherent viscosity of the attachable/detachable covering lens.
7. The method according to claim 6 , wherein the prescription eyeglass lens comprises a special purpose lens.
8. The method according to claim 6 , wherein the attachable/detachable covering lens comprises an attachable/detachable prescription lens.
9. The method according to claim 6 , further comprising providing vision correction via the attachable/detachable covering lens.
10. The method according to claim 6 , further comprising providing reading glass correction via the attachable/detachable covering lens.
