The persistent haze and gloomy weather have not only dampened people's moods but also led to a sharp rise in respiratory illnesses like coughs, colds, and upper respiratory infections. As a result, more people are wearing masks to protect themselves from the poor air quality. However, while masks help shield the nose and mouth, they offer no protection for the eyes.
In fact, prolonged exposure to haze can cause more than just physical discomfort. It can harm the eyes, often referred to as the "windows of the soul," turning them into "frosted glass" or even "broken glass." Recent eye clinics have reported an increase in patients suffering from redness, itching, and irritation. These symptoms are becoming more common as pollution levels rise.
Our eyes are constantly exposed to the air, just like our skin. While we can cover our face with a mask, our eyes remain vulnerable. Although protective eyewear is an effective solution, it can be inconvenient and may cause fogging, making it less practical for daily use.
The cornea, the clear outer layer of the eye, gets 80% of its oxygen directly from the air. The surface of the eye is coated with a thin tear film that helps maintain clear vision and protects the cornea. This tear film is crucial — without it, vision becomes blurry, and the eyes feel dry, tired, and uncomfortable. Prolonged screen time becomes difficult under such conditions.
The tear film also acts as a natural barrier, trapping small airborne particles. When the air is polluted with fine dust, these particles can stick to the tear film and are hard to remove. If they carry harmful bacteria, chemicals, or irritants, they can cause serious damage to the eye’s surface. This leads to symptoms like itchy eyes, pain, and a burning sensation — all of which explain the surge in eye-related issues during hazy weather.
For contact lens wearers, the situation is even worse. Wearing contact lenses adds an extra layer between the cornea and the air, reducing the amount of oxygen reaching the eye. This makes the eyes more sensitive to environmental pollutants. Additionally, the hydrophilic materials used in modern contact lenses can absorb harmful particles, potentially leading to long-term eye health problems.
From a medical perspective, it's advisable to limit outdoor activities during hazy days. Once indoors, using artificial tears can help rinse away any particles that have settled on the eye’s surface, reducing irritation and potential harm. For contact lens users, it's recommended to use care drops specifically designed for use with lenses to keep the eyes clean and comfortable.
As air pollution continues to be a growing concern, protecting our eyes has never been more important. Taking simple preventive measures can go a long way in preserving eye health and ensuring clearer vision in the long run.
