Avoid places with a lot of air movement
This means limiting your exposure to fans and hair dryers, and by wearing wraparound sunglasses when outside on windy days to protect your eyes from drying out.
Turn on a humidifier in the wintertime
Home heating systems can cause the air in your home to dry out, and dry out your eyes. But using a humidifier can help the air stay moist. If you don’t have a humidifier, you can put a pan of water on your radiator to add water into the air.
Rest your eyes
Frequent reading, TV watching, and computer use can dry out your eyes, so it’s important to take breaks so your eyes can regain some of their moisture.
Stay away from cigarette smoke
Cigarette smoke can irritate dry eyes and increase one’s risk of developing dry eyes in the first place.
Use warm compresses then wash your eyelids
Placing a warm compress on your eyes then washing your eyelids with baby shampoo helps to release some of the oil in your eyelids’ glands, this improves the quality of your tears. Be sure you completely rinse soap from your eyes when finished to avoid irritating them.
Try an omega-3 fatty acid supplement
Some people report dry eye relief after adding omega-3 fatty acids to their diet. These can be found naturally in foods like oily fish and flax seeds, but can also be purchased in liquid or pill supplement form.
