The particulate matter settles on the surface of the eyes, resulting in discomfort, irritation, and many other eye conditions. In order to combat this rising threat, it is imperative to know the necessary symptoms, long-term risks, and simple ways to protect the eyes from the dangerous spike in air pollution.

The Science Of Eye Damage: How Pollutants Attack The Eyes

The eyes are a mucous membrane that is directly exposed to the polluted air present in indoor and outdoor spaces. Here are four major pollutants that impact eye health that are present in the hazardous level air quality:

1. Particulate Matter

The particulate matter (PM) 2.5 and PM10 are not just a respiratory system concern, but remain a growing threat to the eyes as well. The tiny irritating particles cause direct irritation that results in constant rubbing of the eyes, which can worsen the problem. Touching the eyes frequently without properly washing your hands can introduce toxins that can damage the sensitive outer layer of the eyes.

2. Ozone

3. Nitrogen Dioxide And Sulfur Dioxide

These two industrial air pollutants can enter the eyes through repeated exposure to polluted air in the outdoors and can also be trapped inside in commercial spaces. The pollutants get dissolved in the tear film of the eyes, forming mild acids and leading to chemical irritation. Along with this serious impact, they also inflame the outer layer of the eyes, which is one of the main causes of swelling.
