Researchers have developed an electronics-free smart contact lens using microfluidics that continuously monitors eye pressure and autonomously delivers glaucoma medication in response. The all-polymer lens addresses key limitations of current treatment—infrequent clinic visits and poor adherence (nearly 50% of patients stop treatment within 6 months). The closed-loop system demonstrated effectiveness equivalent to conventional eye drops in rabbit trials with no biocompatibility issues over 14 days.
