Every time you blink, you spread a teary film across your eye, nourishing the cornea and making the surface clear and smooth. If this natural process isn't working correctly, you'll know it. The likely culprit is a condition called dry eye that causes an irritated and watery sensation, making it hard to keep the eyes open.
“Some people have the sensation that something is scratching or that something is stuck in their eye,” says Jessica H. Chow, MD, a Yale Medicine eye specialist. Dr. Chow and other Yale Medicine specialists are experts in the conditions that cause dry eye and have access to the best resources to treat those conditions.
