Smart Contact Lenses Detecting Eye Afflictions

There are many wearable devices that have been created providing medical advances. One example are contact lenses that are proficient in influencing the physiological information of the eye, the number of tears, and intraocular pressure, which allows the point-of-care (POC) diagnosis of eye diseases.

However, researchers have designed a new “smart” contact lens that has the ability to change colour (alternating from red to green to blue). It can immediately report the real-time changes in moisture and pressure that are vital signs for xerophthalmia and glaucoma diagnosis by altering colours.

The new “smart” contact lens possesses great promise for instrument-free ophthalmic health monitoring and help reduce the high risk of eye disease.
