Abstract
An ophthalmic lens incorporating clearly identifiable, highly visible embedded labels that are not visible to the wearer or others when placed on the eye may be utilized to allow an individual to easily distinguish between the normal state of the lens and the inverted state of the lens as well as serve any number of functions, including acting as a brand label, a prescription label or as a cosmetic enhancer. The embedded label comprises holographic recordings revealed only in transmitted light.

An ophthalmic lens with embedded label, the ophthalmic lens comprising:
- a contact lens;
- and
- one or more embedded structures that are sensitive to the direction of incident light incorporated into the contact lens.
An ophthalmic lens with embedded label, the ophthalmic lens comprising:
- a contact lens;
- and
- one or more embedded structures that influence the propagation of light incident on the contact lens.
A method for fabricating a label for a embedding in a secondary object, the method comprising the steps of:
- depositing a photaligning release material onto a substrate;
- aligning the photaligning release material with a linearly polarized light to create a homogenous background on the substrate;
- arranging a mask on a predetermined position in front of the substrate;
- exposing the homogenous background on the substrate to interfering light beams of orthogonal polarization states through the mask;
- coating the substrate with a reactive liquid crystal film;
- polymerizing the reactive liquid crystal film;
- releasing the polymerized liquid crystal polymer film from the substrate;
- and
- transferring at least a portion of the released film to the secondary object.
