As winter sets in, we prepare ourselves with warm coats, scarves, and gloves — but how often do we think about protecting our eyes? The colder months bring a unique set of challenges for eye health, with biting winds, dry indoor heating, and the surprising threat of UV rays reflecting off icy surfaces. These factors can leave eyes feeling dry, irritated, and vulnerable to long-term damage. By understanding the risks and taking a few simple precautions, you can maintain clear, comfortable vision throughout the season.
Dry Air and Heating: The Hidden Cause of Winter Dry Eyes
One of the most common winter complaints is dry eyes. As temperatures drop, heating systems go into full force, drying out the air in homes, offices, and cars. This lack of moisture can cause the natural tear film on the surface of your eyes to evaporate more quickly, leaving them feeling itchy, irritated, and uncomfortable. People who spend long hours in front of a screen are especially susceptible, as blinking — essential for rehydrating the eyes — becomes less frequent during screen time.
To combat this, it’s a good idea to stay hydrated, increase moisture in the air with a humidifier, and use lubricating eye drops when necessary. These small adjustments can make a significant difference in comfort. If you regularly experience dry eyes, consider taking screen breaks using the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) to help maintain moisture on the eye’s surface.
Cold Winds and Outdoor Exposure: How to Protect Your Eyes Outside
The weather outside presents its own set of problems. Cold, windy days can cause moisture to be stripped from the eyes even faster, leading to a feeling of grittiness or discomfort. People who enjoy outdoor activities like walking, cycling, or running often notice this effect the most. The constant exposure to cold air, especially in windy conditions, can leave eyes feeling sore or irritated.
One simple way to protect your eyes outdoors is to wear wraparound sunglasses or protective goggles. These create a physical barrier between your eyes and the harsh elements, helping to prevent moisture loss. The added bonus? Many sunglasses also offer UV protection, which is essential even in winter. Not only will you shield your eyes from the wind, but you’ll also reduce glare and block out harmful rays from the sun.
The Surprising Risk of UV Rays in Winter
While it’s easy to associate UV rays with summer sunshine, they can be just as harmful during the colder months. Snow and ice reflect UV rays, significantly increasing exposure. This “snow glare” can be harsh on the eyes and, over time, can contribute to cataracts or macular degeneration. Even on cloudy days, UV rays penetrate through the clouds, which means your eyes remain exposed.
To protect yourself, wear sunglasses that block 100% of UVA and UVB rays. Wraparound styles are especially effective since they prevent rays from entering from the sides. Polarized lenses are also an excellent option, as they reduce glare from reflective surfaces like snow and ice, providing clearer, more comfortable vision. If you’re hitting the slopes, ski goggles with UV protection are essential to avoid “snow blindness,” a painful condition caused by overexposure to UV light.
Cold and Flu Season: Preventing Eye Infections
Winter also brings with it the peak of cold and flu season, and with it, an increased risk of eye infections such as conjunctivitis (pink eye). Viruses and bacteria spread quickly through touch, and since we’re all more likely to rub our eyes when they feel dry or irritated, the chance of infection rises. Good hygiene becomes crucial during this period to protect your eyes.
Washing your hands regularly, avoiding face-touching, and steering clear of shared items like makeup applicators, face towels, or pillowcases can all reduce the risk of infection. If you experience persistent redness, discharge, or discomfort, it’s worth seeking advice from an optician, as treatment may be required. Keeping your eyes clean and protected can significantly reduce the chance of irritation and infection.
Contact Lenses: Extra Care for Wearers in Winter
Contact lens wearers may face additional challenges during the winter. The combination of dry air, reduced oxygen flow, and wind exposure can make wearing lenses uncomfortable. Lenses sit directly on the surface of the eye, and if the eye’s tear film dries out, it can cause lenses to feel gritty, sticky, or irritating.
Some people find it helpful to switch to daily disposable lenses in the winter months, as fresh lenses each day reduce the risk of irritation. Others may opt for rewetting drops designed for contact lens wearers to keep eyes feeling fresh throughout the day. If dryness becomes persistent, switching to glasses for a few days can give your eyes a much-needed break. For people who wear contact lenses outdoors during winter sports, goggles or wraparound sunglasses are a must for added protection against wind and UV rays.
