2.         "Technology enables soft contact lenses to monitor medical conditions" - Purdue Research Foundation News

Researchers have developed soft contact lenses that no only correct vision but also can monitor glucose and medical conditions and be used for ocular pain relief or drug delivery. Sensors or other technology previously couldn't be used for soft contact lenses because the technology required a rigid, planar surface incompatible with the soft, curved shape of a contact lens. The Purdue University team, led by Chi Hwan Lee, created... [continue to read]

3.         "Soft contact lens can monitor glucose, medical conditions and deliver drugs" - Wearable Technologies

Researchers at Purdue University have developed soft contact lenses that no only works as a contact lens but also can monitor glucose and medical conditions and be used to track intraocular pressure and drug delivery directly into the eyes. In the past, sensors could not be used for soft contact lenses because it required a rigid, plana surface which is not compatible with the soft, curved shape of a contact lens. The research team, led by Chi Hwan Lee, developed... [continue to read]
