Understanding and Managing Dry Eyes: Steps Towards Lasting Comfort

Dry eyes can be a persistent and bothersome issue, manifesting as a gritty, burning, or stinging sensation in the eyes. The symptoms may fluctuate throughout the day and are often aggravated by certain activities such as prolonged screen use, exposure to wind, or spending time in air-conditioned environments. While the desire for a permanent cure is understandable, the reality is that dry eyes are best managed through ongoing strategies that address both the symptoms and their root causes. A holistic approach, involving lifestyle adjustments and preventive care, can help individuals achieve lasting relief and maintain eye health over time.

What Causes Dry Eyes?

Dry eyes occur when the eyes do not produce enough moisture, or when the moisture evaporates too quickly. Common causes include:

• Environmental factors such as wind, smoke, or dry indoor air
• Prolonged use of digital devices
• Natural changes related to age
• Contact lens wear
• Reduced blinking during focused activities
• Dietary habits that may lack essential nutrients

Signs and Symptoms

• Persistent dryness, scratchiness, or burning sensation
• Redness or irritation
• Watery eyes (a reflex response to dryness)
• Sensitivity to light
• Blurred vision, especially after extended visual tasks

Long-Term Strategies for Managing Dry Eyes

1. Lifestyle and Environmental Adjustments

• Humidify Indoor Air: Using a humidifier at home or in the office can help maintain optimal moisture levels in the air, reducing evaporation from the eyes.
• Limit Exposure to Air Movement: Avoid sitting directly in front of fans, air conditioners, or heaters, as these can accelerate tear evaporation.
• Take Regular Breaks from Screens: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds to reduce eye strain and encourage blinking.
• Wear Protective Eyewear: Sunglasses or wraparound glasses can shield eyes from wind and environmental irritants when outdoors.

2. Eye Care Habits

• Practice Good Eyelid Hygiene: Gently cleaning the eyelids with a warm, damp cloth can help remove debris and support natural moisture production.
• Encourage Regular Blinking: Make a conscious effort to blink more often, especially during activities that require intense focus.
• Remove Eye Makeup Thoroughly: Ensuring all makeup is removed before sleep can prevent irritation and support healthy eyes.

3. Nutrition and Hydration

• Stay Well Hydrated: Drinking sufficient water throughout the day supports overall moisture balance in the body, including the eyes.
• Incorporate Eye-Friendly Nutrients: Foods rich in omega-3 fatty acids (such as salmon, flaxseeds, and walnuts), vitamin A (carrots, sweet potatoes), and vitamin E (almonds, spinach) can support eye health.

4. Mindful Use of Contact Lenses

• Follow recommended guidelines for contact lens wear and care.
• Consider taking breaks from lenses or switching to glasses when experiencing dryness.

5. Regular Eye Check-Ups

• Routine visits to an eye care professional can help identify underlying issues and provide personalised advice for long-term comfort.

When to Seek Professional Advice

If dry eye symptoms persist despite consistent self-care, or if there is a sudden change in vision, it is important to consult an eye care professional. Persistent discomfort may indicate an underlying issue that requires further assessment. Early intervention can prevent complications and support long-term eye comfort.

Preventive Tips for Ongoing Relief

• Maintain a balanced diet and stay hydrated
• Minimise exposure to dry or windy environments
• Prioritise regular blinking during focused tasks
• Keep indoor spaces well-ventilated but not overly dry
