Dry Eyes: Causes, Symptoms, Prevention, and Treatment

Introduction: Why Dry Eyes Are a Growing Problem

Dry eye syndrome is one of the most common eye conditions worldwide, affecting millions of people of all ages. Whether you’re working long hours in front of a screen, exposed to dry environments, or dealing with underlying health issues, chances are you’ve experienced the itching, burning, or gritty feeling of dry eyes.

Studies show that up to 30% of adults report chronic dry eye symptoms, and with increased screen time, that number continues to rise. The good news? With the right prevention strategies and treatments, dry eyes can be managed effectively.

What Are Dry Eyes?

Dry eyes occur when your eyes don’t produce enough tears, or when the tears evaporate too quickly. Tears are not just “water”; they’re a complex mixture of mucus, oil, and water that protect and lubricate your eyes.

When this balance is disrupted, your eyes become irritated, red, and uncomfortable — a condition medically known as keratoconjunctivitis sicca.

Causes of Dry Eyes

1. Environmental Factors

Prolonged screen use (computers, smartphones, tablets).
Air conditioning, heating, or dry climates.
Exposure to wind, smoke, or pollution.

2. Medical Conditions

Autoimmune disorders like Sjögren’s syndrome.
Diabetes, thyroid disease, and rheumatoid arthritis.
Hormonal changes during menopause.
