Dry eyes are a common problem that, if prolonged, can cause discomfort, mild pain, and sometimes blurred vision. Many everyday habits can be the culprit behind this lack of necessary moisture.

Improper contact lens use can disrupt the natural tear film, especially if lenses are worn for extended periods without proper cleaning. Some contact lens types can exacerbate dryness by absorbing moisture from the eyes. It's crucial to give your eyes a break when possible and adhere to lens hygiene and wear instructions.

Excessive screen time on computers, laptops, and smartphones is a prevalent cause of dry eyes today. These devices reduce blinking frequency, which normally moistens the eye's surface. Less blinking leads to dryness, irritation, and an increased risk of infection. To combat this, follow the 20-20-20 rule: every 20 minutes, look at an object about 20 feet away for 20 seconds. This also reduces eye strain and encourages natural blinking.

Dehydration from insufficient water intake reduces tear production. A diet low in omega-3 fatty acids also weakens the eye's oil layer, which prevents tear evaporation. To avoid this, drink plenty of water and increase your intake of omega-3-rich foods like salmon, sardines, chia seeds, and walnuts.

Incorrect air conditioner use can accelerate tear evaporation. Avoid directing airflow directly at your face and consider using a humidifier to maintain appropriate moisture levels in your home. This helps prevent dry eyes.

Eye makeup, such as eyeliner and mascara, can block oil glands near the eyelashes. Skincare products containing alcohol or retinoids can also irritate the eye area, affecting the stability of the tear film. Choose gentle products and thoroughly remove makeup and cleanse the eye area every night to reduce dryness.

Rubbing your eyes, which are very sensitive, disrupts tear production and can introduce debris, leading to inflammation and dryness. Apply a cold compress or rinse your face and eyes with clean water when they feel irritated.

Exposure to UV rays, wind, and heat can accelerate tear evaporation. Wearing sunglasses outdoors, especially during summer, can protect your eyes from these elements.
