Dry Eyes in Winter? Causes, Symptoms and Treatment Options

Quick answer: Dry eyes in winter are often caused by cold wind, lower humidity, indoor heating, and increased screen time—all of which can accelerate tear evaporation and disturb the tear film. Symptoms may be temporary or point to an underlying condition like dry eye disease. An optometrist can identify the cause and recommend appropriate treatment.

Gritty, watery, tired, or burning eyes during an Auckland winter are more common than most people realise. Cold southerlies, heat pumps running at full blast, and long hours in front of a screen can all disturb the tear film and cause tears to evaporate faster than usual—especially when these factors combine. For some people, the discomfort settles once they're out of the wind or away from a heater. For others, winter simply makes an existing tear-film problem harder to ignore.

Why Do Eyes Feel Drier in Winter?

Winter doesn't automatically cause dry eye disease, but the seasonal conditions in Auckland can trigger symptoms or make an already unstable tear film noticeably worse. Understanding what's affecting your eyes is the first step toward finding the right approach.

Cold Air, Wind, and Lower Humidity

Cold outdoor air holds less moisture than warm air, and when wind is added to the equation, the rate of evaporation from the eye's surface increases significantly. For contact lens wearers or anyone with a fragile tear film, a blustery walk can quickly leave eyes feeling raw and irritated. The North Shore's exposure to coastal winds makes this especially relevant during the cooler months.

Indoor Heating and Airflow

Stepping inside doesn't necessarily help. Heat pumps, electric heaters, and car heating systems all reduce indoor humidity and circulate dry air—often blowing directly toward the face. An office with overhead heating, a bedroom with a wall-mounted heat pump, or a commute with the car heater on full can all create conditions that draw moisture away from the eye surface throughout the day.

Screen Use and Reduced Blinking

Colder months tend to push people indoors and toward screens. The problem is that concentrating on a computer, phone, or television causes the blink rate to drop, and many of those blinks are incomplete. A full blink spreads a fresh layer of tears across the eye. Partial blinks leave areas of the eye surface exposed, allowing tears to evaporate more quickly between blinks.

How Winter Conditions Affect the Tear Film

The tear film is a thin, layered coating that protects and lubricates the surface of the eye. It also creates the smooth optical surface needed for clear vision. The two most relevant layers are the aqueous layer—the watery component produced by glands above the eye—and the lipid layer, a fine film of oil produced by meibomian glands in the eyelids that slows tear evaporation.

Aqueous-deficient dry eye occurs when the lacrimal glands don't produce enough of the watery layer. Meibomian gland dysfunction (MGD) occurs when the eyelid glands become blocked or produce poor-quality oil, allowing tears to evaporate too quickly. Winter conditions can amplify the symptoms associated with either problem, which is why the season often prompts people to seek help for something that has been quietly building for some time.

Common Winter Dry Eye Symptoms

Winter dry eye symptoms can vary quite a bit from person to person. The most frequently reported include:

• Grittiness or a sandy feeling in the eye
• Burning, stinging, or soreness
• Red or irritated eyes
• Watery eyes caused by reflex tearing
• Fluctuating or temporarily blurred vision
• Sensitivity to light
• Eye fatigue, particularly toward the end of the day
• Difficulty wearing contact lenses comfortably

Watery eyes are worth a specific mention. It can seem counterintuitive, but excessive tearing is often associated with dry eye. When the tear film is unstable, the eye responds by producing a surge of reflex tears—but these tears don't contain the balanced combination of water and oil needed to stabilise the eye's surface. The result is eyes that water persistently without ever feeling properly comfortable.

Is It Temporary Irritation or Dry Eye Disease?

Mild symptoms caused by a specific trigger—stepping into a strong wind, sitting too close to a heater, or spending an unusually long time at a screen—often settle once that trigger is removed. The tear film can recover, and the discomfort fades.

The pattern becomes more significant when symptoms return regularly across different environments, persist after the obvious trigger has gone, begin affecting vision, or require frequent use of eye drops just to get through the day. Difficulty wearing contact lenses that were previously comfortable is another indicator worth taking seriously.

This distinction matters because temporary irritation and dry eye disease call for different responses. A proper assessment can tell the difference. If symptoms are affecting daily comfort or vision, it's worth having an optometrist take a closer look rather than managing solely with drops.

Why Eye Drops May Provide Only Short-Term Relief

Artificial tears can reduce discomfort and temporarily lubricate the eye surface, which is genuinely useful. They don't, however, correct the underlying cause—whether that's blocked meibomian glands, insufficient tear production, or inflammation driving the instability.

Not all eye drops are the same, either. Products formulated for aqueous-deficient dry eye work differently from those designed to support the lipid layer. Using a product that doesn't match the type of dry eye someone has may provide little benefit, or in some cases, make things worse. Our page on eye drops for dry eye care explains the different types and what each is designed to address.

How NVISION Identifies the Cause of Dry Eye

At NVISION Eyecare, we offer a detailed dry eye evaluation to determine the type and severity of what's happening with the tear film. The assessment uses advanced diagnostic equipment and examines tear volume, tear evaporation rate, the structure and function of the meibomian glands, the quality and thickness of the oil layer, and blinking patterns.

These findings allow our optometrists to identify whether symptoms are primarily related to aqueous deficiency, meibomian gland dysfunction, or a combination of both—and to recommend a treatment approach based on that specific picture rather than a general assumption.

Winter Dry Eye Treatment Options

Treatment is always guided by assessment findings. Not every option listed here will be appropriate for every patient, and our optometrists will discuss what makes sense given the type and severity of dry eye identified.

Daily Support for Winter Eye Comfort

For mild or situational symptoms, practical changes can make a meaningful difference. Redirecting heater vents away from the face, using a humidifier in a consistently dry room, taking regular screen breaks, and making a conscious effort to blink fully during prolonged screen use can all reduce the burden on the tear film. Wrapping-style glasses or sunglasses offer some protection against wind when outside. Eye drops recommended for your specific type of dry eye can support comfort during this period, without replacing a proper treatment plan if one is needed.

These measures help manage symptoms. They don't treat the underlying condition if dry eye disease is present.

LipiFlow for Blocked Meibomian Glands

Where meibomian gland dysfunction is contributing to poor oil flow, LipiFlow treatment may be considered. LipiFlow uses controlled warmth and gentle pressure applied to the inner eyelid surface to help clear gland blockages and encourage healthier oil secretion. It is an in-clinic procedure and is not appropriate for everyone—candidacy depends on the assessment findings.

IPL for Evaporative Dry Eye

Intense pulsed light therapy may be recommended for selected patients with evaporative dry eye or meibomian gland dysfunction. IPL dry eye treatment targets inflammation and can help improve the quality of the oil layer over time. It involves a course of sessions and is not suitable for all patients or skin types.

Rexon-Eye for Chronic Dry Eye

Rexon-Eye is a non-invasive treatment applied over closed eyes using a mask-style device. It uses low-power, high-frequency electric fields and is delivered across four 20-minute sessions. NVISION Eyecare may consider Rexon-Eye for selected patients following a dry eye evaluation, particularly where other approaches haven't provided sufficient relief.

Low-Level Light Therapy

Low-level light therapy is another in-clinic option that may be included as part of an individually designed treatment plan. As with all treatments at our practice, it would only be recommended where the assessment supports it.

When Should You See an Optometrist About Dry Eyes?

An assessment is worth booking if symptoms return frequently across different environments, don't settle after removing the obvious trigger, begin affecting your vision or daily comfort, disrupt contact lens wear, or require eye drops several times a day just to feel manageable.

A dry eye evaluation won't just confirm whether dry eye disease is present—it will identify the factors contributing to the symptoms and guide a response that's specific to what's actually going on.

Frequently Asked Questions

Why do eyes feel dry in winter specifically?
Cold air, wind, lower humidity, indoor heating, and increased screen use all cause tears to evaporate from the eye surface more quickly. These factors often occur together during winter, which is why symptoms can feel more pronounced during the cooler months—even in people who don't have underlying dry eye disease.

What is the difference between temporary dry eye and dry eye disease?
Temporary irritation typically clears once the triggering condition—wind, heating, screen use—is removed. Dry eye disease is a chronic condition where the tear film is persistently unstable, regardless of the environment. Symptoms that recur frequently, affect vision, or require regular eye drops may indicate an underlying condition worth assessing.

Can I treat dry eyes in winter with over-the-counter eye drops?
Artificial tears can reduce discomfort temporarily, but they don't address the underlying cause. The type of drop matters too—products formulated for aqueous-deficient dry eye differ from those targeting the lipid layer. An optometrist can advise which product is appropriate for your situation.

What does a dry eye evaluation at NVISION Eyecare involve?
The evaluation examines tear volume, tear evaporation rate, meibomian gland structure and function, oil layer quality, and blinking patterns using advanced diagnostic equipment. The results allow our optometrists to identify the type and severity of dry eye and recommend a treatment approach tailored to those findings.

Is meibomian gland dysfunction related to winter dry eye symptoms?
MGD can cause evaporative dry eye year-round, but winter conditions—particularly indoor heating and cold wind—tend to accelerate tear evaporation, making symptoms associated with MGD more noticeable. An assessment can confirm whether MGD is a contributing factor.
