Researchers in South Korea developed experimental smart contact lenses with tiny electrodes that deliver retinal electrical signals using temporal interference to target mood-related brain circuits in mice, improving depression-like behavior in animals with damaged retinas; the approach is early-stage, not tested in healthy retinas, and many challenges remain before any human use.
Researchers developed flexible, drug-free contact lenses with ultrathin electrodes that use temporal interference to stimulate mood-regulating brain circuits via the retina. In depressed mice, 30-minute daily sessions for three weeks improved behavior, restored hippocampus–prefrontal cortex connectivity, and shifted biomarkers (serotonin up ~47%, corticosterone down ~48%, reduced brain inflammation) to levels similar to fluoxetine, suggesting the eye could noninvasively influence brain mood networks. The approach is not yet ready for humans and will require safety testing, wireless integration, and personalized tuning before clinical trials.
