Eyes that photosynthesize: Scientists plant a cure for dry eye disease

What if eyes could use light to heal themselves? Drawing inspiration from how plants harness sunlight, researchers at the National University of Singapore (NUS) are pioneering a revolutionary treatment for dry eye disease. Their approach uses a light-activated technology derived from the photosynthetic membranes of the spinach plant, enabling the eye to stay continuously hydrated. This offers a solution that is simple, effective, and non-invasive.
