Tunable apodized multiple-focus ophthalmic devices and methods characterized by a lens with multiple optical zones each with an optical power optimized for one or more focal lengths and a tunable apodization mask positioned within at least a portion of the optical zone(s). Upon a desired change of focus for the wearer, an optical transmission characteristic of the tunable apodization mask may be varied. The tunable apodization mask may take the form of an electrochromic device or another suitable material.

A contact lens having an electronic system is described herein to provide lens accommodation using a distance measurement determined from an ultrasound time of flight signal. In at least one embodiment, the contact lens includes an ultrasound module, a system controller, a timing circuit, and an actuator. In at least one embodiment, the ultrasound module includes at least one transducer configured to emit a sound pressure wave outwardly and receive a reflected sound pressure wave from an object. A timer may track an elapsed time between generation and detection of the sound pressure wave by the at least one transducer to determine the distance to the object. In at least one embodiment, lens accommodation is further achieved using a communication link between a pair of contact lenses to determine a convergence angle based on independent distance measurements generated by each contact lens.

A personal hygiene device may have a main body with an absorbent material configured to absorb a fluid, a sensor disposed within the main body, and a controller configured to communicate with the sensor. The sensor has a conductor and an insulator containing at least a portion of the conductor, and the sensor is configured to detect a first electrical value and a second electrical value that is different from the first electrical value. The sensor is also configured to transmit a signal to the controller upon detection of the second electrical value.

Methods and systems for adaptive configuration of ophthalmic devices are disclosed. An example method may comprise receiving, by a first sensor system disposed on or in a first ophthalmic device, sensor data representing movement of an eye of a user, wherein the first ophthalmic device is disposed within or upon an eye of the user; causing, based on the sensor data, storage of a history of movement of the eye; determining, based on the history of movement, a dwell characteristic indicating a distance at which the eye is fixated when an event occurs; and causing output of a signal indicative of performing an action in response to determining the dwell characteristic.

Ophthalmic lenses incorporate multifocal properties for the purpose of slowing, retarding, controlling or preventing myopia development or progression, correcting presbyopic vision or allowing extended depth of focus. The lens has electronically controlled adjustable focus where the change in focus oscillates so rapidly that it is imperceptible to human vision.

The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a selection layer configured to reject light from the eye within a first range of incident angles and allow light from the eye within a second range of incident angles to pass through the selection layer. The sensor system may comprise a plurality of photodiodes disposed below the selection layer and configured to detect the light from the eye within the second range of incident angles that is allowed to pass through the selection layer. The sensor system may comprise an output circuit electrically coupled to the plurality of photodiodes and configured to output a signal indicative of which photodiode of the plurality of photodiodes detected the light.

Systems and methods for pupil size detection

Programmable timer circuits are disclosed. One timer circuit may include a reference circuit configured to generate a bias current, a current controlled oscillator configured to receive the bias current c, and a frequency divider network configured to divide an output of the oscillator. The timer circuit may be capable of timing for 24 hour period, while using less than 5nA of quiescent current.

Methods and apparatus to enhance levels of oxygen in tear fluid under a worn advanced contact lens are described. The advanced contact lens may include an insert which is impermeable to fluid flow across its body. The method of enhancement may include creating pores through the insert, creating channels in portions of the contact lens body, including layers of absorptive material, including devices to generate or release oxygen or means of moving tear fluid under the contact lens.

Designs, strategies and methods for forming tube shaped batteries are described. In some examples, hermetic seals may be used to seal battery chemistry within the tube-shaped batteries. This may improve biocompatibility of energization elements. In some examples, the tube form biocompatible energization elements may be used in a biomedical device. In some further examples, the tube form biocompatible energization elements may be used in a contact lens.

The present invention provides a method of making a mask for patterning a three-dimensional substrate. A mandrel includes a form machined in a surface corresponding to a shape of the substrate. A layer of material is deposited in a first region of the form and a metal layer is deposited in a second region of the form. A portion of the mandrel is subsequently removed. The present invention also provides a method of patterning a three-dimensional substrate with a mask.
