Posted on November 22, 2017

Levels of toxic air pollution in Delhi and the surrounding areas are on the rise and if experts are to be believed, the air we all are inhaling is laden with obnoxious gases and harmful pollutants. Some studies on the pollution have revealed that the air quality in NCR is as bad a smoking forty cigarettes in a day. This extreme pollution in the form of smog affects our respiratory systems, causes allergies and damages our eyes. Compromised quality of air contains harmful gases such as carbon monoxide, nitrogen dioxide and coarse dust particles which have to lead to more number of people complaining of red and watery eyes and various eye allergies.

What is smog and how it can affect your health?

Smog is a dense layer of air which forms near the ground when air pollution is high. It is a common phenomenon in built-up cities where traffic is high or areas near industries with high emissions. Smog is formed when sunlight reacts with the gases (car fumes/ industrial emissions) in the lower atmosphere. Some people are more sensitive to its effects than others including those with lung or heart complaints. The first signs of health problems caused due to smog are irritation in nose, throat, lungs, and eyes. In some cases, breathing can also be impacted.

The human eye can get affected by even the slightest level of pollution, and therefore the moment we come into the contact of air pollution, the blanket of poisonous gases and harmful substances can cause a range of eye infections. The ones who spend most of their day involved in the outdoor activities are affected by air pollution the most. It can also have harmful implications for school going children and people who prefer an early morning walk; hence it recommends staying indoors and avoiding any strenuous exercises when the air quality is poor. The reason being it does more harm to the body than any good.

The most common eye conditions caused due to air pollution/ smog are:

  • Watery eyes
  • Burning sensation
  • Redness
  • Swelling
  • Dry eyes
  • Itching
  • Allergic reactions

Studies have also linked high levels of pollution to dry eye syndrome which is a chronic condition in which eyes are unable to produce the right amount of tears to stay wet. Hence, the lack of moisture makes your eyes feel itchy and causes a burning sensation. In extreme cases, this dryness can even damage the surface of the eyes which can cause vision problems. Eye infections should not be ignored and a doctor should be consulted if you experience, redness, watery eyes, irritation and blurred vision before it is too late. While you can’t prevent dry eye syndrome as the chances of acquiring it increase with pollution and age, there are many steps to that can be of help to minimize the risk of infections. Let’s know what these are:

  • Stay up to date with the weather forecasts and smog; keep a check on the daily air quality index. If possible try to avoid visiting the areas where air quality is poor. If it is difficult to avoid visiting such places, stay indoors and keeps doors and windows closed.
  • Though exercises are good for health, avoid them in smoggy conditions, when ground ozone levels are at their peak.
  • Wash your hands often and try not to touch your eyes
  • Stay hydrated as it will aid in adequate tear formation. It becomes imperative when external factors such as smog increase your chances of dry eyes and eye irritation. Drinking eight to ten glasses of water will be a good choice.
  • Have a healthy diet rich in Omega 3 fatty acid including lots of green leafy vegetables, carrots, spinach, almonds, walnuts, berries and fish which are extremely good for the eyes.
  • Wear sunglasses when outdoors
  • Do not rub your eyes
  • Lubricate your eyes with eye drops, these are easily available over-the-counter, however, it’s important to get your eyes examined before using any eye drops.
