Condition

Dry eye

Dry eye happens when your tears can’t keep the front of your eye moist and comfortable. It is common, and there are many ways to ease it.

Key points

Common signs
Dry, gritty, burning or watery eyes, and blurry vision that clears when you blink.
Who’s at risk
Older adults, women, contact lens wearers and people who spend long hours on screens.
How it’s found
Your eye doctor looks at your eyelids, oil glands and tears with a microscope, and may use a harmless dye.
Treatment
Eye drops, warm compresses, eyelid care and daily habits. Some people need prescription drops, office treatments or tear duct plugs.

Every time you blink, a thin layer of tears spreads over the front of your eye. Tears keep your eye moist, wash away dust and help you see clearly. The tear layer has water, mucus and a thin film of oil on top that stops the water from drying up too fast.

Dry eye happens when this tear layer stops doing its job. There are two main kinds, and many people have some of both:

  • Your eyes don’t make enough tears. This is more common with age and with some health conditions.
  • Your tears dry up too fast. This is the most common kind. It often happens when tiny oil glands along the edge of your eyelids get blocked or don’t work well, so the tears lack the oil that keeps them from drying out.

Dry eye is very common. It can be mild and come and go, or it can last a long time. It is usually not dangerous, but it can make everyday things like reading, driving and screen work uncomfortable.

  • Eyes that feel dry, gritty or scratchy, or like something is in them
  • Burning or stinging
  • Redness
  • Blurry vision that gets better when you blink
  • Eyes that get tired quickly
  • Being bothered by wind, smoke or bright light
  • Watery eyes. This sounds strange, but dry, irritated eyes can make extra tears that don’t help much
  • Trouble wearing contact lenses

Symptoms are often worse at the end of the day, after screen work, or in dry or windy places.
