New Self-Healing Contact Lenses Can Repair Themselves in UV Light
Reported byScienceAlert ↗·Sourced by Goodlede
Chemists Jung-Hyun Choi and Byoung-Ki Cho developed contact lenses using disulfide cross-linkers that self-heal surface scratches within one hour under ordinary UV light, restoring approximately 90% of structural stability while also improving scratch resistance and water retention comparable to current soft lenses.
Self-healing lenses are in lab development; clinical testing and regulatory approval for human use remain ahead.
