Winter may bring relief from harsh sunlight, but for contact lens users, it quietly introduces a new set of challenges. Cold winds outdoors and artificially heated indoor spaces dramatically reduce humidity levels, accelerating moisture loss from the eyes.
The result is a noticeable rise in dryness, irritation, redness, and discomfort, which is often mistaken for routine seasonal sensitivity. For many, winter also increases the risk of eye infections and lens-related complications if care routines are not adjusted to the changing environment.
Why Winter Triggers Dryness And Irritation
“Winter is a season when we see a noticeable spike in complaints related to contact lens discomfort,” explains Dr. Rashmi Barve, M.S., Consulting Eye Surgeon at Oculus Eye Clinic Centre for Comprehensive Eye, Check Up & Surgery, Thane. She notes, “Cold winds and low humidity significantly reduce the natural moisture levels on the eye’s surface, causing lenses to dehydrate faster.”
Echoing this, Dr. Piyush Gupta, Cornea & Laser Specialist at Prakash Eye Hospital and Laser Centre, Delhi, adds, “Environmental changes lead to a drop in tear film stability, particularly affecting people with borderline dry eyes. As tear evaporation increases, lenses rub more against the cornea, increasing friction and irritation.”
The Role Of Heated Indoor Air
While outdoor cold is unavoidable, indoor heating often worsens the problem. “The risk is higher for those who spend long hours in heated indoor environments,” says Dr. Barve, pointing out that tear film evaporation accelerates indoors. Sitting directly in front of heaters or car blowers can worsen dryness and even cause micro-abrasions on the cornea if lenses are worn for extended periods.
Lubrication, Wear Time, And Lens Choice Matter
One of the simplest yet most overlooked winter precautions is regular eye lubrication. Dr. Barve advises using preservative-free lubricating eye drops two to three times a day to maintain comfort. She also recommends reducing lens wear time during winter, especially if dryness or irritation is already present.
Dr. Gupta highlights the importance of proper lens fit, stating that ill-fitting lenses tend to move excessively over the cornea when the eyes are dry. Winter, he says, is an ideal time to reassess prescriptions or switch to daily disposable lenses, which reduce protein buildup and infection risk.
Hygiene: Your First Line Of Defence Against Infection
Strict hygiene becomes even more critical during winter. “Never rinse lenses with tap water,” cautions Dr. Barve, warning that it can introduce harmful microorganisms. She stresses the importance of using fresh multipurpose solution every time and avoiding low-quality cosmetic lenses purchased from unregulated sources.
Dr. Gupta reinforces this by advising lens users to never sleep with lenses on and to replace lens cases every three months. He also warns against wearing lenses during colds or flu, as inflammation makes the eyes more vulnerable to infection.
Hydration is not just about eye drops. “Drinking adequate water, taking short breaks during screen time, and consciously blinking more often help keep the eyes lubricated,” says Dr. Gupta. Using humidifiers at home or workspaces can also restore moisture to the air, making lens wear more comfortable.
Winter doesn’t have to mean compromised vision or constant discomfort for contact lens users. By increasing lubrication, adjusting wear time, maintaining strict hygiene, and being mindful of environmental triggers, most winter-related eye issues can be prevented.
