Ophthalmic device with built-in self-test circuitry for testing an adjustable lens |
| abstract |
An ophthalmic device includes an enclosure that is compatible for wearing in or on an eye. An adjustable lens is disposed within the enclosure. Driver circuitry is disposed within the enclosure and coupled to drive the adjustable lens and change its optical power. Built-in-self-test (BIST) circuitry is disposed within the enclosure and coupled to the adjustable lens. The BIST circuitry includes an impedance measurement circuit coupled to selectively measure an impedance of the adjustable lens. A controller is disposed within the enclosure and includes BIST control logic that measures the impedance of the adjustable lens with the impedance measurement circuit to determine a health status of the adjustable lens. |
