When COVID-19 took over the world, most of us thought it only affected the lungs. But as time passed, experts began to notice that it was not just a respiratory illness. According to a 2023 study published in the Journal of Ophthalmic Research, nearly 11% of COVID-19 patients experienced some form of eye-related problem during or after infection. These symptoms were often overlooked or misunderstood.
The corona effect on eyes is real. It is subtle, often mistaken for regular eye strain and can be a warning sign of deeper issues. Some people experience redness. Others complain of blurry vision or constant irritation. In rare cases, the virus can even cause serious infections like conjunctivitis.
This blog is here to help you understand exactly how Corona effect on eyes, what signs to watch for and what precautions you can take to stay safe.
Can COVID-19 Really Affect the Eyes?
Yes, it can. In fact, the corona effect on eyes has been observed across different age groups and in patients with both mild and severe symptoms. The virus spreads through droplets and can enter the body through the mucous membranes—this includes the mouth, nose and eyes.
Your eyes are exposed throughout the day. You touch them without realising. You rub them when they itch. If your hands are carrying the virus, it can enter your system through this route. That’s why it is important to treat your eyes with as much care as you treat your lungs or throat.
A report by the American Academy of Ophthalmology also noted that some COVID-19 patients showed eye symptoms even before testing positive, which means your eyes can give early signs of infection.
Early Signs of the Corona Effect on Eyes
The eyes often give clues when something is wrong in the body. During or after a COVID-19 infection, watch out for these specific signs. Each of these may be a part of the corona effect on eyes and it is important to recognise them early.
1. Redness That Won’t Go Away
Mild redness can happen due to tiredness or allergies. But if your eyes stay red for more than two days, feel hot, or look bloodshot, it could be a sign of viral conjunctivitis. In COVID-related cases, redness is often accompanied by irritation or a burning sensation.
2. Dry and Gritty Sensation
If your eyes feel like they are filled with dust or you experience a gritty feeling, it is not something to ignore, this is a Corona effect on eyes. COVID-19 can reduce natural tear production, which leads to dryness. People with long COVID symptoms have often reported persistent dryness that continues for weeks after recovery.
3. Blurry or Cloudy Vision
Blurry vision can make daily tasks difficult and it’s stands as one of the sign of Corona effect on eyes. You may feel like your eyes are fogged up or cannot focus properly. This can happen when inflammation caused by the virus affects the retina or cornea.
4. Swelling Around the Eyes
Under-eye puffiness or eyelid swelling is another warning sign. This swelling may be more noticeable in the morning. If not treated, it can cause discomfort and lead to other infections.
5. Sensitivity to Light
If you suddenly feel uncomfortable in bright light or find yourself squinting more than usual, this is something to pay attention to. It may indicate inflammation in the deeper layers of the eye, triggered by the virus.
How Long Do These Symptoms Last?
The corona effect on eyes may last from a few days to several weeks. Some people recover quickly with rest and eye drops. Others may need medical attention, especially if the symptoms grow worse or start affecting their vision. Long COVID sufferers have reported eye discomfort even 3 to 6 months after infection, according to data from The Lancet.
Remember: Just because your other symptoms are gone doesn’t mean your eyes are completely safe.
Who is at Higher Risk?
Certain groups are more likely to face eye-related issues during or after a COVID infection. These include:
- People with diabetes or high blood pressure
- Those who wear contact lenses regularly
- Elderly patients with low immunity
- Children, whose eyes may be more sensitive
- Individuals with pre-existing eye conditions like dry eye syndrome or conjunctivitis
In these cases, the corona effect on eyes can be more severe and may require prompt treatment.
What Can You Do If You See These Signs?
You do not need to panic, but you do need to act. If you notice any of the Corona effect on eyes signs listed above, follow these steps immediately:
1: Avoid Touching or Rubbing Your Eyes: Your eyes are sensitive. Rubbing them when they’re already irritated can worsen the problem or spread the infection.
2: Clean Your Eyes Gently: Wash your eyes using clean, filtered water. Avoid using random eye drops or home remedies without checking with a doctor first.
3: Reduce Screen Time: Long hours on screens can increase eye dryness. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
4: Stay Hydrated: Drink plenty of water every day. This helps keep your eyes moist and reduces inflammation naturally.
5: Use Lubricating Eye Drops: If you feel constant dryness, lubricating drops (prescribed by an expert) can bring relief. Do not self-medicate.
6: Consult an Eye Doctor: Do not delay professional care. The earlier you visit a doctor, the better your chances of recovery.
Precautions to Protect Your Eyes During and After COVID
Prevention is always better than treatment. Whether you are currently infected with the Corona effect on eyes, recovering, or just trying to stay safe, these daily habits can help protect your eyes:
- Always wear a mask and keep a safe distance
- Wear glasses (instead of contact lenses) when going outside
- Avoid sharing towels, pillowcases, or cosmetics
- Wash your hands frequently and avoid touching your face
- Use a humidifier in dry rooms to maintain moisture in the air
- Eat eye-friendly foods like green leafy vegetables, citrus fruits and nuts rich in Vitamin A and E
These steps not only protect you from the corona effect on eyes, but also improve your overall eye health.
Don’t Confuse It with Common Eye Problems
It is easy to think that dry eyes or blurry vision are just due to tiredness or screen time. But if these symptoms appear suddenly, especially after you have had COVID or were exposed to someone who had it, do not take them lightly.
Many people who ignored early signs later developed long-term complications. So, if something feels “off” about your eyes, trust your instinct and get them checked.
