Abstract
Techniques and mechanisms for determining an amount of accommodation for an ophthalmic system are described. In an embodiment, the ophthalmic system includes a first circuit and a second circuit, each comprising a respective photodiode. The second circuit is configured to provide a light response profile that is more linear than a light response profile provided by the first circuit. Light sensing by the first circuit results in generation of a first signal indicating a level of ambient light in a surrounding environment. Other light sensing by the second circuit results in a second signal being generated. An amount of accommodation is determined based at least in part on the second signal.
