What Are Dry Eyes
When the quantity or quality of tears fails to keep the surface of the eye lubricated and moisturized, people may start experiencing dry eyes. Tears are required to maintain the health of the front surface of the eye and for clear vision. Dry eyes can sting, burn or cause a gritty sensation that feels like sand in the eyes. Itching, redness, sensitivity to light, blurry vision are some other symptoms of dry eyes. Exposure to air conditioning or heating, computer or screen time, certain medications, and aging are some of the factors that can cause dryness of the eyes.
Eye Drops and Their Shortcomings
Artificial tears, or eye drops, are usually recommended by doctors for people who experience dry eyes. These are available over the counter and lubricate the eyes by mimicking the composition of natural tears. However, prolonged use of artificial tears can wash away the natural defenses of the eyes, making the eyes more vulnerable to infections. Additionally, some people may be allergic to the preservatives that are added in the artificial tears. These preservatives may cause blurriness in eyes or discomfort.
Home Remedies for Dry Eyes
While eye drops may be effective in providing temporary relief, some home remedies may help in reducing the frequency and severity of dry eyes:
Blink Frequently
Most people reduce their blink rate when using a computer or reading. This can lead to decreased production of tears, causing the eyes to dry out. Blinking 10-15 times every minute can reduce the dryness of the eyes.
Use a Warm Compress
Applying a warm compress on the eyes can open the clogged oil glands, thus improving the quality of tears. One can use a warm towel or an eye mask that can be heated in a microwave. Be sure to use clean towels with warm water and avoid using very hot water as it can cause burns.
Omega-3 Fatty Acids
Omega-3 fatty acids are known to reduce inflammation in the body and can help in reducing the symptoms of dry eyes. Sources of these include fatty fish (salmon, sardines), fish oil supplements, flaxseed oil, and chia seeds. Eating food rich in omega 3 fatty acids can help in reducing the dryness of eyes.
Dry eyes can be an uncomfortable experience, but there are a range of home remedies that one can try. Popular methods include applying a warm compress to the eyes, taking Omega-3 supplements and ensuring that you increase your blink rate while working at the computer. If your dry eyes persist or cause you significant discomfort, be sure to check in with your optician or GP for expert advice.
