An electrically controlled spectacle includes a spectacle frame and optoelectronic lenses housed in the frame. The lenses include a left lens and a right lens, each of the optoelectrical lenses having a plurality of states, wherein the state of the left lens is independent of the state of the right lens. The electrically controlled spectacle also includes a control unit housed in the frame, the control unit being adapted to control the state of each of the lenses independently.

Techniques and mechanisms for sensing an overlap of an ophthalmic device by an eyelid of a user while the ophthalmic device is disposed in or on an eye of the user. In an embodiment, a circuit, disposed in a sealed enclosure of the ophthalmic device, interacts via an electromagnetic field with a film of tear fluid that is formed on the ophthalmic device. Based on the electromagnetic interaction, an oscillation characteristic of the circuit is evaluated. The oscillation characteristic varies with a resistance that is due in part to an eyelid of the user overlapping at least some portion of the ophthalmic device. Based on the evaluated oscillation characteristic, an amount of the eyelid overlap is determined by circuitry of the ophthalmic device. In another embodiment, the amount of eyelid overlap is used to determine one or more characteristics of gazing by the user's eye.

Contact lenses that have an ion-impermeable portion and an ion-permeable portion that are able to move on the eye without binding to the eye are described. The contact lenses exhibit an average ionoflux transmittance of at least 1.34×10.sup.−4 mm/min. One or more electronic components can be included in the contact lenses. Methods of making the contact lenses are also described.

A lens for spectacles and spectacles a resin and a near-infrared absorbing agent having a maximum absorption wavelength in a thiourethane resin in a range of more than 700 nm and 1000 nm or less and a transmittance of light at 400 nm of 50% or more and 100% or less.

Improved eyewear is disclosed. The eyewear comprises a frame member and a lens. The eyewear also includes circuitry within the frame member for enhancing the use of the eyewear. A system and method in accordance with the present invention is directed to a variety of ways to enhance the use of eyeglasses. They are: (1) media focals, that is, utilizing the eyewear for its intended purpose and enhancing that use by using imaging techniques to improve the vision of the user; (2) telecommunications enhancements that allow the eyeglasses to be integrated with telecommunication devices such as cell phones or the like; and (3) entertainment enhancements that allow the eyewear to be integrated with devices such as MP3 players, radios, or the like.

Disclosed is a method for testing the feasibility of a pair of spectacles, the pair of spectacles comprising an identified spectacle frame. The method includes steps of: a) acquiring a range of values of at least one first parameter relating to a spectacle wearer, in all of which range it is desired to ensure the feasibility of the pair of spectacles, b) acquiring a range of values of at least one second parameter that relates to a spectacle wearer and that is different from each first parameter, in all of which range it is desired to ensure the feasibility of the pair of spectacles, c) confirming, for a characteristic number of values of each second parameter, that the pair of spectacles is feasible whatever the value of each first parameter comprised in its range.

An eye-mountable device is provided that includes an eyelid occlusion sensor. The eyelid occlusion sensor is used to detect winks, squints, downwards glances or looks, blinks, or other eye-based gestures generated by the user. Based on the detected gestures, an optical power of an adjustable lens of the device may be changed or some other operations could be performed by the eye-mountable device. Such operations could include toggling the optical power of the lens between first and second power levels due to the user squinting, looking downward, or performing some other gesture. Additionally or alternatively, such operations could include setting the optical power of the lens to a first optical power unless the user is looking downward, in which case the optical power of the lens could be set to a second optical power.

Improved wearable optics is disclosed. The wearable optics comprises a frame member and a lens. The wearable optics also includes circuitry within the frame member for enhancing the use of the wearable optics. A system and method in accordance with the present invention is directed to a variety of ways to enhance the use of eyeglasses. They are: (1) media focals, that is, utilizing the wearable optics for its intended purpose and enhancing that use by using imaging techniques to improve the vision of the user; (2) telecommunications enhancements that allow the eyeglasses to be integrated with telecommunication devices such as cell phones or the like; and (3) entertainment enhancements that allow the wearable optics to be integrated with devices such as MP3 players, radios, or the like.
