Why Delhi’s Air and Your Phone Are Secretly Ruining Your Eyes

Post by : Saif Nasser

In Delhi, eye doctors are treating more patients than ever before. Many complain about dry, red, or itchy eyes. Experts say the main reason is the city’s dirty air and people’s habit of using mobile phones and computers for long hours. Both these factors are silently harming people’s vision.

When Air Turns Into a Danger

Every winter, Delhi’s air becomes thick with smoke and dust. Vehicles, factories, and burning crop waste fill the air with harmful particles. These tiny particles can enter the eyes easily and cause pain or dryness.
Eye specialist Dr. Chetan explains, “Polluted air does not only damage the lungs. It also hurts the eyes. It makes them dry, itchy, and sensitive to light.”

When the Air Quality Index (AQI) goes above safe levels, even a short walk outside can cause irritation. Polluted air blocks the tear glands that keep eyes moist. Over time, this can cause dry eye syndrome — a problem where eyes stop making enough tears. Without enough tears, dust and bacteria stay in the eyes, leading to infection and blurred vision.

The Hidden Harm from Screens

Pollution is not the only reason for Delhi’s eye troubles. The second major cause is long hours in front of screens. People now spend most of their day on phones, laptops, and tablets. This causes what doctors call “digital eye strain.”

Normally, a person blinks 15–20 times each minute. But while looking at screens, that number falls to just 5–6. When blinking reduces, eyes lose moisture. As a result, they start burning, feel heavy, and become tired quickly.
Dr. Chetan says, “Many young people and office workers have headaches and eye pain because they spend all day looking at screens. The bad air makes it worse.”

The Role of Blue Light

Screens also give off blue light, a high-energy light that goes deep into the eyes. This light can disturb sleep and cause damage to the retina after long exposure. Studies say too much blue light can increase the risk of vision problems in the future.

Children are most at risk. They spend hours on online classes, video games, and social media. Doctors fear this could lead to nearsightedness (myopia) and other eye problems at a young age.

What You Can Do to Protect Your Eyes

Experts say small changes can make a big difference.

Limit screen time and follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.

Wear sunglasses or clear protective glasses when you go outside to protect against polluted air.

Use doctor-recommended eye drops to keep your eyes moist. Never use random “cooling” or “whitening” drops without advice.

Eat healthy foods like carrots, spinach, almonds, and fish that help keep your eyes strong.

Keep indoor air clean by using air purifiers and avoiding cigarette smoke.

The Importance of Regular Check-ups

Doctors say many people ignore early signs like itching or dryness. But these small problems can turn serious if not treated. Regular eye check-ups can help detect issues early. “Eyes are delicate. Once the damage begins, it’s hard to reverse,” said Dr. Chetan.

A Wake-Up Call for the City

Delhi’s pollution is unlikely to go away soon, and technology will only grow. But people can still protect their vision through awareness and discipline. Our eyes connect us to the world, and losing that gift due to neglect would be tragic.
