If you often feel like you have grit or sand in your eyes, you may be suffering from a chronic dry eye condition.

This common condition is also known as keratoconjunctivitis sicca (KCS), which happens when your eyes fail to produce enough tears to keep them moist and comfortable. Symptoms of dry eye include itching, burning, and redness, which can also lead to blurred vision. Dry eye can be caused by a variety of factors, such as aging, hormonal changes, medication side effects, and environmental factors like dry air.

Here are six tips for managing chronic dry eye:.

1. Use a humidifier

The lack of moisture in the air can worsen dry eye symptoms, especially during the winter months. Using a humidifier in your home or office can add moisture to the air and help keep your eyes hydrated.

Choose a cool mist humidifier, as hot mist can actually dry out your eyes more. Place the humidifier near your workspace or bed to help relieve dryness.

2. Blink frequently

When you spend long hours focusing on a computer screen or reading, you may blink less frequently, which can cause dry eyes. Blinking helps distribute tears across the surface of your eyes and keeps them moist.

Make an effort to blink more often, even if it means taking short breaks throughout the day. You can also try the 20-20-20 method, which involves looking away from your computer screen every 20 minutes and focusing on something 20 feet away for 20 seconds.

3. Use lubricating eye drops

Over-the-counter eye drops can provide temporary relief for dry eye symptoms. Look for preservative-free artificial tears, which are designed to mimic the natural tears your eyes produce.

Avoid eye drops that promise to “get the red out,” as these drops contain vasoconstrictors that can worsen dry eye symptoms. You can also consult your eye doctor about prescription eye drops or ointments that can help manage chronic dry eye.

4. Eat a healthy diet

What you eat can affect your eye health. Foods that are rich in omega-3 fatty acids, such as salmon and flaxseed, can help reduce inflammation and improve the quality of your tears.

Vitamin A, found in carrots, sweet potatoes, and spinach, is also important for eye health. Drinking plenty of water can also help keep your body hydrated and your eyes moist.

5. Avoid environmental triggers

Dry eye symptoms can worsen in certain environments, such as smoky or windy areas. If you smoke, consider quitting, as smoking can worsen dry eye symptoms. You can also wear wrap-around sunglasses to protect your eyes from wind and dust.

If you work in front of a computer for several hours, try to position the monitor so that it is slightly below eye level, which can help reduce dry eye symptoms.

6. Practice good eye hygiene

Good eye hygiene can help prevent infections and reduce dry eye symptoms. Avoid touching your eyes with your fingers, as this can transfer bacteria from your hands to your eyes. Instead, use a clean tissue or cotton swab to remove dust or debris.

Make sure to replace your contact lenses and their case regularly, as bacteria can build up on the surface. Finally, get annual eye exams to monitor your eye health and catch any conditions early.
