Eyewear for eliciting a blink response and measurement system thereof

A system for triggering a blink response, comprising:

• a sensor configured to detect a blink in at least one eye;
• a lens including a plurality of layers, at least one of the plurality of layers comprising an electrodynamic layer in communication with the sensor;
• wherein the electrodynamic layer is configured to adjust a lens between a first state and a second state in response to a first signal;
• wherein the electrodynamic layer is configured to adjust the lens between the second state and the first state in response to a second signal;
• and
• a controller in communication with the sensor and the electrodynamic layer of the lens, the controller being configured to generate the first signal and the second signal based on signal communication with the sensor, and
• wherein the controller is configured to generate the second signal upon receipt of a blink verification signal from the sensor;
• and
• the controller is configured to generate the first signal after a time interval has elapsed, the time interval beginning upon receipt of the blink verification signal by the controller.
