Abstract
A device may create an optical obstruction such as a haze for a predetermined amount of time in front of one or more eyes of the user and thereby trigger a blink response in the user. The device may include a lens having a plurality of layers and a sensor configured to detect a blink it at least one eye. At least one of the plurality of layers may include an electrodynamic layer in communication with the sensor. The electrodynamic layer may be configured to adjust the lens from a first state to a second state in response to a first signal from the sensor and from the second state back to the first state in response to a second signal from the sensor. The second state may include an at least partial obstruction of vision through the lens.
