Self-Healing Contact Lenses Activated by Ultraviolet Light Technology
Dankook University in South Korea has announced the development of self-healing contact lenses based on a hydrogel material reinforced with disulfide bonds. This technology allows the lenses to automatically repair minor scratches within one hour when exposed to ultraviolet light. The new technique, which restores approximately 90% of the lens’s structural stability, enhances the lenses' resistance to scratching and bacteria, while also maintaining eye moisture. This advancement boosts the lenses' competitiveness with current options and paves the way for the development of the next generation of medical optical devices.
