Abstract
An electro-active contact lens system and a method for making the electro-active contact lens system is disclosed. The system includes a contact lens, an electro-active element attached to the contact lens, a view detector attached to the contact lens and in electronic communication with the electro-active element, and a power source attached to the contact lens. In certain embodiments, the view detector may be a rangefinder which determines the distance of an object being viewed and these embodiments further include a means to stabilize the rangefinder between the opening of the eyelids when the electro-active contact lens system is worn by a wearer. The electro-active contact lens system provides electro-active vision correction of one or more focal lengths.
Claims34
An electro-active contact lens system comprising:
- a contact lens;
- an electro-active element attached to the contact lens;
- a view detector attached to the contact lens and in electronic communication with the electro-active element;
- a power source attached to the contact lens to provide power to the electro-active element and the view detector;
- and
- a means for stabilizing the view detector between a palpebral fissure of a patient's eye when the contact lens system is worn by the patient.
A method for making an electro-active contact lens system comprising:
- encapsulating an electro-active element;
- attaching the encapsulated electro-active element and a power source to provide power to the electro-active element to a contact lens;
- and
- attaching a view detector in electronic communication with the electro-active element to the contact lens;
- and
- stabilizing the view detector on the contact lens between a palpebral fissure of a patient's eye when the contact lens is worn by the patient.
An electro-active contact lens that includes an electro-active element, a view detector in communication with the electro-active element, and a power source that provides power to the electro-active element, wherein the electro-active element and the view detector are contained within a capsule.
An electro-active contact lens system comprising:
- a contact lens including an electro-active element;
- a view detector in communication with the electro-active element;
- and
- a power source to provide power to the electro-active element, wherein the view detector comprises a tilt switch.
An electro-active contact lens system comprising:
- a contact lens including an electro-active element;
- a view detector in communication with the electro-active element;
- and
- a power source to provide power to the electro-active element, wherein the view detector comprises one of a micro gyroscope or micro accelerometer.
An electro-active contact lens that includes an electro-active element, a view detector in communication with the electro-active element, a power source that provides power to the electro-active element, and a means for stabilizing the view detector between a palpebral fissure of a patient's eye when the electro-active contact lens is worn by the patient.
