Early detection of glaucoma with ‘smart’ contact lenses


Most people with early-stage glaucoma don’t know they have it, even though early treatment is key to reducing vision loss. While detecting a subtle increase in eye pressure helps doctors to diagnose glaucoma, it’s challenging to monitor continuously, especially with the variety of temperatures eyes experience.

Now, researchers in ACS Applied Materials & Interfaces report a prototype “smart” contact lens that measures eye pressure accurately, regardless of temperature. The researchers say that their dual-circuit “smart” lens design has potential to be used for accurate early detection and monitoring of glaucoma, even in a wide range of temperatures.
