Protecting Your Cornea During Monsoon: Understanding the Risk of Keratitis
25 September 2026
The monsoon season brings relief from the heat, but it can also create conditions that increase the risk of certain eye problems. Increased humidity, contaminated water, dust, mud and poor hygiene can expose our eyes to bacteria and fungi.
One condition that deserves particular attention during this season is keratitis, an inflammation or infection of the cornea—the transparent front surface of the eye.
What Is Keratitis?
Keratitis occurs when the cornea becomes inflamed or infected. It can be caused by bacteria, fungi, viruses or parasites.
If treatment is delayed, keratitis can sometimes lead to corneal scarring, reduced vision and, in severe cases, permanent visual impairment.
Why Can the Risk Increase During Monsoon?
During the rainy season, eyes may come into contact with:
• Contaminated rain or floodwater
• Mud and dust
• Dirty hands
• Fungal spores present in the environment
• Contaminated water sources
• Foreign particles entering the eye
People who wear contact lenses may also have an increased risk of serious corneal infections if lenses are not handled and cleaned properly.
Common Symptoms of Keratitis
Watch for symptoms such as:
• Eye pain
• Redness
• Excessive watering
• Sensitivity to light
• Foreign-body sensation
• Blurred or reduced vision
• Eye discharge
• A white or grey spot appearing on the cornea
A combination of eye pain, redness and reduced vision should not be ignored.
How Can You Protect Your Cornea?
- Avoid Touching or Rubbing Your Eyes
If rainwater, mud or dust enters your eye, avoid rubbing it. Rubbing can cause irritation or even damage the corneal surface. - Wash Your Hands Regularly
Always clean your hands before touching your eyes, applying eye drops or handling contact lenses. - Be Careful With Contaminated Water
Avoid exposing your eyes to dirty rainwater, floodwater or untreated water. - Follow Proper Contact Lens Hygiene
Never sleep or swim while wearing contact lenses unless specifically advised by your eye-care professional. Use recommended lens solutions and follow the prescribed replacement schedule. - Don’t Self-Medicate
Do not use leftover antibiotic or steroid eye drops for unexplained redness or pain. Some eye conditions can worsen with inappropriate treatment, particularly steroid use in certain infections.
When Should You See an Eye Doctor?
Seek an ophthalmologist’s evaluation promptly if you experience:
• Persistent eye pain
• Increasing redness
• Blurred or decreasing vision
• Significant light sensitivity
• Persistent watering or discharge
• A visible white spot on the cornea
• Symptoms following an eye injury or exposure to contaminated water
Early diagnosis and appropriate treatment can help protect the cornea and preserve vision.
Takeaway
Your cornea is delicate and essential for clear vision. During the monsoon, simple precautions such as good hand hygiene, avoiding contaminated water, maintaining contact-lens hygiene and avoiding self-medication can reduce the risk of serious eye problems.
If you develop pain, redness or blurred vision, don’t wait for the symptoms to become severe. Get your eyes examined by an ophthalmologist.
Healthy eyes need protection in every season—including the rainy season.
