NUS Scientists Harness Plant Photosynthesis to Treat Dry Eye Disease

Dry eye disease causes corneal scarring, chronic pain, blurred vision, sensitivity to light, and linked depression and anxiety affecting 1.5 billion people worldwide.

In Singapore, scientists have done something quietly extraordinary: they have taught human cells to borrow the sun-harvesting machinery of plants. Researchers at the National University of Singapore have developed LEAF, a spinach-derived technology that, when delivered as ordinary eye drops, reverses the cellular damage of dry eye disease — a condition that afflicts 1.5 billion people worldwide — by producing protective antioxidants using nothing more than ambient light. It is a reminder that the boundaries between kingdoms of life are more porous than we imagined, and that healing sometimes a
