A new technological development allows researchers, for the first time, to monitor changes in pupil size and gaze direction behind closed eyes using touchless infrared imaging. In the future, tracking ...

Chronic ophthalmic diseases are multivariate, time-varying, and degenerative. Smart contact lenses have emerged as a scalable platform for noninvasive ocular signal detection and disease diagnosis.

Assessments of gaze direction (eye movements), pupil size, and the pupillary light reflex (PLR) are critical for neurological examination and neuroscience research and constitute a powerful tool in ...
