Colour changing lens that detects eye damage.

Scientists have developed a colour changing contact lens that can detect a key marker of eye injury in minutes-a time frame crucial to treating eye trauma.
The researchers from university of Illinois used the sensor called ‘OJOGEL’to measure ascorbic acid levels in artificial tears and in clinical samples of fluid from patient’s eyes. The gel laden with gold nano particles changes colour when it reacts with a tear drop.
