New Self-Healing Contact Lenses Can Repair Themselves in UV Light
Scientists have developed contact lenses that can repair minor scratches when exposed to UV light, using a special hydrogel material with disulfide cross-linkers. These molecules allow the lenses to re-form broken bonds under UV exposure, restoring up to 90% of their structural integrity. The lenses also show improved scratch resistance and water retention compared to traditional materials, potentially reducing waste and health risks. This innovation could lead to more durable and safer contact lenses in the future.
Scientists have created contact lenses that can repair tiny scratches when exposed to UV light.
This could reduce waste, lower costs, and improve eye health by keeping lenses safe and functional longer.
It shows how smart materials can solve everyday problems with sustainable, practical solutions that benefit people.
