The present invention relates to a contact lens for diagnosis and treatment of dry eye syndrome. The contact lens, according to the present invention, may diagnose dry eye syndrome by means of a change in an electric current occurring as a result of a field effect when a dry eye syndrome biomarker binds to a probe, and when dry eye syndrome is diagnosed, generates an electric current so that a gold film blocking a drug reservoir melts by the electric current, thereby enabling the release of a drug to be controlled.

The invention relates to mental health and using technology that can analyze and interpret hormones from drops of sweat and also a peer to peer feedback system to predict mental health issues (such as depression) in an individual. The invention further relates to the monitoring of sweat and feedback and interpreting the two in tandem to identify symptoms of mental health illnesses in an individual over a period of time (to predict and prevent that certain mental health disease). Furthermore, the records of the sweat analysis and peer to peer feedback will be utilized to provide smart suggestions and track the mental health of an individual.
