For some people, treating dry eyes requires treatment for a medical problem that's causing the condition, or a doctor will need to prescribe special medication to help your eyes produce more water. more eyes.
In addition, you can treat dry eyes at home by the following methods:
Use warm towels to press on the eyes: Tears are formed from 3 layers, including the fat layer, the water layer and the mucus layer. Your eyes need all three parts to stay hydrated and healthy. Inflamed and flaky eyelids can clog the eyelid glands leading to dry eyes. To relieve eye irritation, use a clean washcloth dipped in warm water, wring it out and place it over your eyes, and close your eyes for at least a minute. Gently press on the edge of the eyelid. The heat helps loosen the clogged oil in the glands. Regularly wet the towel with warm water. You should do this every day to reduce inflammation, even if your eye condition gets better.

Cleaning your eyelids: Cleaning your eyelids, as well as the surrounding skin and hair, can help control blepharitis. Apply a small amount of baby shampoo or soap to your fingertips and gently massage the skin around your eyelashes with your eyes closed. Blink more: Staring at a computer will limit the number of times you blink per minute. So, try to blink often when you use the computer or watch TV or use the phone. Follow the 20/20 rule: after 20 minutes of using the computer, close your eyes for 20 seconds. Another simple tip to keep your eyes moist while using a computer: Place your monitor below eye level. You won't have to keep your eyes wide open, which can help slow the evaporation of tears between blinks.
Omega-3 fatty acid supplements: Salmon and tuna, or sardines, trout and mackerel all contain omega-3 fatty acids. Research shows that these healthy fats help the oil glands in your eyes function better, which can reduce irritation. Other foods that are naturally high in omega-3 fats include walnuts, vegetable oils (such as canola and soybean oils), and flaxseeds. You can also take an omega-3 fatty acid supplement in pill form. You should consult with your doctor before deciding to take an omega-3 fatty acid supplement to make sure it won't affect any health problems or medications you're taking.
Drink enough water: all parts of your body need water to maintain and function, including your eyes. Drinking enough water helps keep your eyes moist. But don't wait until you are thirsty to drink water because by then, your body is already mildly dehydrated.
Instead, you should drink 8 to 10 glasses throughout the day. If you don't want to use water, you can choose other water-rich foods like rat or watermelon, except for drinks that contain alcohol or caffeine.
Another way to check if your body is getting enough water is by urine color. If your urine is colorless or pale yellow, your body is getting enough water.
Wear sunglasses: this can help protect your eyes from wind, sunlight, which cause tears to evaporate faster. In addition, you should also avoid blowing air from a hair dryer, air conditioner or fan towards your eyes.
