For India’s nearly 10 million contact lens users, the monsoon brings more than just rain and humidity, it’s also a season when extra care for eye health becomes very important. The humid weather, polluted rainwater, and damp surroundings create the perfect breeding ground for bacteria and fungi. Doctors warn that during this season, people who wear contact lenses face a higher risk of eye infections such as conjunctivitis, keratitis, and even corneal ulcers.
So, does that mean you need to give up contact lenses until the rains are over? Not necessarily. Experts say contact lenses can be worn safely in the monsoon, but only if you take extra precautions.
Why monsoons pose a risk for lens wearers
According to Dr Rasika R Thakur, Cornea and Phaco-Refractive Surgeon at Dr Agarwals Eye Hospital, Kalyan, “The monsoon season increases the risk of eye infections because rainwater is often contaminated with bacteria and other germs. If this water comes into contact with your lenses, it can cause serious issues, from conjunctivitis to corneal ulcers.”
Rainwater, tap water, or even bottled water are unsafe for cleaning lenses. If these get trapped under a lens, they can irritate the eyes or lead to severe infections.
Why lenses feel uncomfortable in rainy weather
You may have noticed your lenses feeling sticky, blurry, or less comfortable on a rainy day. Dr Thakur explains that humidity changes can cause lenses to swell, while staying indoors in AC may dry them out. “This sudden shift in moisture can make your lenses feel uncomfortable or even affect your vision,” she says.
Five golden rules for wearing lenses in the monsoon
- Prioritize hygiene
Always wash and dry your hands thoroughly before touching your lenses. Even a small amount of moisture can carry bacteria, which increases the risk of infection.
- Protect your eyes from rainwater
If possible, avoid wearing lenses while walking or driving in the rain. Glasses are a safer option, as they not only protect your eyes from rain but also block dust and allergens.
- Switch to daily disposable lenses
If your prescription allows, consider using daily disposable lenses during the monsoon. Dr Thakur says, “Daily disposables are a great option because they reduce the chances of contamination — you use a fresh pair every day and don’t need to store or clean them.”
- Never clean lenses with water
Always use the recommended lens solution for cleaning and storing your lenses. Replace your lens case every two to three months to avoid bacterial buildup.
- Look out for warning signs
Redness, itching, watering, or blurry vision should never be ignored. If you notice these symptoms, remove your lenses immediately. “Delaying treatment can worsen infections and cause long-term damage,” warns Dr Thakur.
When in doubt, take a break
Even with the best precautions, your eyes may sometimes need rest. Experts recommend giving your eyes a “no-lens day” once a week. Wearing glasses for a day can help your eyes breathe and recover.
Glasses and sunglasses can help protect your eyesight
Switching to glasses during heavy rains is not a compromise. In fact, glasses act as a shield against rain, wind, and harmful UV rays, which can still penetrate through clouds. For those who prefer lenses, wearing protective sunglasses over them offers double protection.
The monsoon doesn’t mean you need to pack away your contact lenses, but safety rules become even more important. Prioritise hygiene, avoid rain exposure, and see your doctor at the first sign of discomfort.
“A little extra caution during the monsoon can go a long way in protecting your eyes,” says Dr Thakur. “Your eyes deserve the same care as the rest of your health.”
