Cyclosporine A (CyA) is effective in treating chronic dry eyes and contact lens mediated dry eyes. CyA is delivered through eye drops of an oil-in-water emulsion, which has a small residence time in the eyes, leading to low bioavailability. Here we explore delivery of CyA from contact lenses to provide ...

Attractive faces are appealing: We like to look at them, and we like to be looked at by them. We presented attractive and unattractive smiling and neutral faces containing identical eye regions with different gaze directions. Participants judged whether or not a face looked directly at them. Overall, attractive faces ...

Humans' tendency to follow others' gaze is considered to be rather resistant to top-down influences. However, recent evidence indicates that gaze following depends on prior eye contact with the observed agent. Does observing two people engaging in eye contact also modulate gaze following? Participants observed two faces looking at each ...
