Learn what causes winter dryness and how dry eye light therapy can support tear film health and soothe irritation in cold, dry conditions.
Introduction
If your eyes feel extra dry and itchy each winter, you're not alone. Cold weather has a way of making things worse for anyone already dealing with irritation or tired eyes. You step outside and the air feels sharp, then head back indoors where the heat is cranked up and the air feels just as dry.
Many people look for relief this time of year, especially when dry eye symptoms feel like a normal part of winter. But just because it’s common doesn’t mean you have to live with it. Understanding why winter affects your eyes so much, and how dry eye light therapy fits into your care routine can make this season feel a little easier on your vision.
What Happens to Your Eyes in Cold Weather When the temperature drops, everything gets drier, your skin, lips, and especially your eyes. During winter, outdoor air holds less moisture. Then indoor heat kicks in and pulls even more humidity from the environment. That mix can quickly upset your eye’s normal moisture balance.
Your eyes rely on tears to keep the surface healthy and to help you see clearly. But when the surrounding air doesn't hold enough moisture, the tears can dry up faster than your eyes can replace them.
On windy days, the thin layer of moisture over your eyes evaporates even faster. Add in the fact that your eyelid glands may slow down their natural oil production in colder weather, and you’ve got a recipe for dry, red, uncomfortable eyes.

A healthy tear film needs both water and oil to work properly. Without the oil layer, tears don’t stick around, they dry up or roll off your eye. Winter throws that whole system off balance, which is often why eyes feel so gritty or watery even when you're not crying or emotional.
Winter Habits That May Make Dry Eyes Worse
It’s not just the cold and dry air that’s tough on your eyes. The way we live during winter months matters too. The more time we spend indoors, the more likely certain habits add to the trouble.
Here are a few common winter patterns that can make dry eye symptoms worse:
• More screen time than usual. Whether for work or relaxation, we tend to blink less when staring at screens, which gives your eyes fewer chances to refresh moisture.
• Blasting the heater. Whether it’s the furnace at home or the vents in your car, direct warm airflow dries out your eyes fast, even if you don’t feel it right away. • Poor indoor lighting. With fewer daylight hours, we rely more on overhead or harsh artificial lights, which can cause eye strain and worsen discomfort.
Small lifestyle tweaks can sometimes help, but when the habits are part of your daily routine for months at a time, the impact on your eyes adds up.• Blasting the heater.

How Dry Eye Light Therapy May Help
When everyday steps don’t seem like enough, some people look for more targeted ways to
support their eyes through the season. That’s where dry eye light therapy may come in. This type of therapy uses specific wavelengths of red light to help your eyes at the cellular level. It works by supporting how cells produce energy and helping encourage the natural function of glands near your eyelids.
With Arunalight red light glasses, that light comes from a 670nm medical red wavelength that has been studied for eye health and for supporting blood flow and cellular energy. That can lead to more stable tear production and less inflammation. By using this therapy regularly, often in short sessions of about 3 minutes, the glands that produce the oily part of your tears may work better. The glasses use multiple small red light diodes to cover the eyes and surrounding skin, and those oils help slow down how quickly tears evaporate, which keeps your eyes feeling more comfortable.
Dry eye light therapy isn’t meant to replace regular care, but might become a helpful part of your winter routine. Some people add it to their mornings, others near the end of the day. What matters most is consistency during the season where your eyes need the most support.Tips to Protect and Soothe Your Eyes During Winter
If your eyes are feeling dry right now, there are a few simple things you can try that don’t involve major changes. These steps won’t fix everything on their own, but may help your eyes feel more comfortable as temperatures stay low:
• Use a humidifier. Adding moisture to the air inside your home can create a better environment for your eyes.
• Wear wraparound sunglasses. Keeping your eyes shielded from wind and cold air helps
preserve the tear film when you're outside.
• Stay hydrated. Drinking plenty of water every day helps support tear production from the inside out.
• Take screen breaks. Every 20 minutes, look at something far away for 20 seconds to help
refresh your eyes and remind yourself to blink more.
These actions don’t take a lot of time, but can make a noticeable difference when paired with more direct ways of supporting your vision during dry seasons.• Wear wraparound sunglasses. Keeping your eyes shielded from wind and cold air helps

Clearer Eyes and Comfort All Season Long
Dry winter air, indoor heat, and day-to-day habits all come together to make this time of year hard on your eyes. But dry, red, or uncomfortable eyes don’t have to be just another part of the season.
By understanding what affects your vision during colder months and trying simple ways to protect your eyes, you can stay more comfortable all winter. When lifestyle changes aren’t cutting it, adding an option like light therapy may offer extra support for your tear film and oil glands.
