Abstract
Official abstract text for this publication.
Designs, apparatus and methods to form contact lenses with aesthetic elements on demand are described. In some examples, the method of defining the aesthetic aspect includes printing patterns. Other examples include photochromic or thermochromic elements which may provide patterning on exposure to electromagnetic irradiation. In some further examples, energized components in contact lenses may provide aesthetic characteristics.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of displaying a pattern in a contact lens comprising: forming a contact lens comprising: an insert device, the insert device comprising: an energization element; an electroactive layer comprising an aligned liquid crystal material surrounded by a first and second electrode, wherein an application of an electrical potential across the first and second electrode changes an orientation of molecules of the liquid crystal material which reduces a transmission of electromagnetic radiation through contact lens, and wherein the electroactive layer is located in a non-optic zone of the contact lens; a controller, wherein the controller controls the electrical potential that is applied across the first electrode and the second electrode; and a communication device, wherein the communication device receives data relating to a pattern that determines whether the electrical potential is applied by the controller; transmitting a communication from an external device to the communication device within the contact lens; and placing the contact lens upon an eye of a user.
