One of the long term impacts of Corona is Dry eyes, says research; Here’s how to deal with it

by Shatakshi Gupta

It has now been more than two years yet the effect of corona on the human body is not completely known.  Although the immediate and apparent symptoms of corona are cough, cold, fever, and loss of smell sense, obscure and far-reaching effects of this virus are still under study. Recently, scientists from the Chinese University of Hong Kong have found in a research that 20% of people suffering from corona have reported the problem of dry eyes. In dry eyes, tears either do not form or dry quickly and cause irritation in the eyes.

 What does the research say?

 Researchers examined 228 patients who had recovered from corona between 1 and 3 months. The health records of these patients were compared with those of 109 healthy people. It was found that 1 out of every 5 people infected with corona have symptoms of dry eyes disease.  In addition, these people also reported the blurring of the eyes, sensitivity to light, and swelling of the eyes.

 Another research has been done in 2021 on finding the connection between COVID-19 and the eyes. It was said that 1 out of every 10 corona patients is facing problems related to eyes.

As the name suggests, Dry eyes mean dryness in the eyes. If eyes do not get enough lubrication, then people start facing problems like the inability to form tears, dry tears, burning sensation, swelling, and pain in the eyes.

Effect of corona on the eyes:

Various researches have corroborated the fact that due to corona, people are facing issues like blurring, loss of eyes, and light sensitivity. It is believed that the cause of eye disease may be a link between the corona and the ACE2 enzyme. It is only with the help of the ACE2 enzyme that the corona enters the human body. After this, the virus infects the cells present in our eyes, which causes problems in the eyes.


Researchers have told that the symptoms of dry eyes caused by corona usually go in a few weeks. If the problem is too intense, then one should immediately consult an ophthalmologist. Mild cases, on the other hand, can be treated with simple home remedies.

  • Avoid going out in the strong wind, smoke, and if not possible use sunglasses to prevent direct exposure of these things to the eyes.
  • Drink plenty of water.
  • Use a humidifier to retain moisture in the air.
  • Use warm compressions after wetting eyelids.
  • You can use non-prescription OTC eye drops.
  • Try to reduce the screen time, if not possible use better quality of glasses.
  • Add Omega-3 fatty acids in your diet.
