Why Are Dry Eyes Worse in Winter?
As temperatures drop and the winter months approach, many people notice that their eyes become increasingly dry, irritated or uncomfortable. Cold weather, strong winds and changes in indoor environments can all contribute to worsening dry eye symptoms. Experiencing dry eyes in winter time is particularly common because environmental conditions can affect the tear film, the protective layer of moisture covering the surface of the eyes. Spending more time indoors with central heating can also reduce humidity levels, causing tears to evaporate more quickly. Combined with exposure to cold outdoor air and winter winds, this can leave the eyes feeling dry, gritty and irritated.
For people who already have dry eye disease, these seasonal changes can make existing symptoms more noticeable. However, winter conditions can also trigger temporary discomfort in people who do not usually experience dry eyes.
Understanding what causes dry eye symptoms, recognising when they may indicate an underlying condition and knowing which treatments are available can help you maintain better eye comfort throughout the colder months.
What Causes Dry Eyes in Winter Time?
There are several reasons why dry eyes in winter time can become more noticeable. Although cold weather is an important contributing factor, changes in your surroundings and daily habits can also affect the quality and stability of your tear film.
1. Cold Weather and Strong Winds
Exposure to cold outdoor air and strong winds can increase tear evaporation, leaving the surface of the eyes less adequately lubricated. When walking outdoors, cycling or spending time in exposed environments, the wind can disrupt the tear film and contribute to irritation. People with existing dry eye disease may find these conditions particularly uncomfortable, experiencing increased stinging, watering and sensitivity.
2. Indoor Heating and Low Humidity
One of the most common contributors to dry eyes in winter time is the increased use of central heating. Heating systems can reduce indoor humidity, creating a drier environment that encourages tears to evaporate more quickly. Sitting close to radiators, using electric heaters or spending extended periods in heated offices can make symptoms worse. Although indoor heating provides warmth during colder weather, prolonged exposure to dry air can affect the comfort of your eyes.
3. Increased Screen Time
During winter, people often spend more time indoors, which can mean increased screen use. Whether working at a computer, watching television or using a mobile phone, prolonged periods of concentration can cause us to blink less frequently. Blinking helps distribute tears evenly across the surface of the eye. When we blink less often, the tear film can become unstable, contributing to dryness and irritation. Taking regular breaks from screens and making a conscious effort to blink fully can help reduce discomfort.
4. Reduced Tear Production
Dry eye disease can occur when the eyes do not produce enough tears to maintain adequate lubrication. Tear production can be affected by several factors, including ageing, hormonal changes, certain medications and underlying medical conditions. Although cold weather does not necessarily cause reduced tear production, winter conditions can aggravate symptoms in people whose eyes already produce insufficient tears.
What Are the Symptoms of Dry Eyes?
Dry eye symptoms can vary from person to person, depending on the underlying cause and severity of the condition.
For some, symptoms are occasional and relatively mild. For others, persistent irritation can interfere with everyday activities, including reading, driving, working and wearing contact lenses.
Common symptoms include:
- Grittiness: A sensation that something is trapped in the eye, often described as having sand or grit in the eyes.
- Burning or stinging: Discomfort that can become more noticeable when exposed to cold air, wind or indoor heating.
- Redness and irritation: The eyes may appear red or feel sore and uncomfortable.
- Excessive watering: Although it may seem unusual, dry eyes can trigger increased tear production as the body responds to irritation.
- Blurred or fluctuating vision: An unstable tear film can temporarily affect visual clarity.
- Sensitivity to light: Bright lights may become uncomfortable, particularly when the eyes are already irritated.
- Eye fatigue: The eyes may feel tired, particularly after prolonged screen use or reading.
- Sticky or stringy discharge: Some people experience mucus or sticky secretions around the eyes.
If you regularly experience these symptoms, particularly if they worsen during colder months, it is worth seeking professional advice to establish whether you have dry eye disease or another underlying eye condition.
How Can You Manage Dry Eyes in Winter Time?
While you cannot always avoid cold weather or indoor heating, there are several practical steps that may help reduce discomfort and support better tear film stability.
1. Protect Your Eyes Outdoors
Wearing glasses or sunglasses with a wraparound design can help shield your eyes from cold winds and environmental irritants. This can be particularly helpful when walking, cycling or spending extended periods outdoors during winter.
2. Avoid Direct Exposure to Heating
Try to avoid sitting directly in front of radiators, electric heaters or air conditioning vents. Using a humidifier may also help increase moisture levels in indoor environments, particularly in rooms where central heating is used regularly.
3. Take Regular Screen Breaks
Extended screen use can contribute to dry eye symptoms because people tend to blink less frequently when concentrating. Taking regular breaks, looking away from your screen and making a conscious effort to blink fully can help maintain the tear film.
4. Use Suitable Eye Drops
Artificial tears, also known as ocular lubricants, can help supplement the natural tear film and relieve symptoms such as dryness, burning and irritation. There are different formulations available, including eye drops and gels. Preservative-free preparations may be recommended for people who need to use lubricants frequently, as preservatives can irritate the eyes in some individuals. It is important to remember that lubricating eye drops help manage symptoms but may not address the underlying cause of dry eye disease.
5. Apply Warm Compresses
Warm compresses can help manage symptoms associated with meibomian gland dysfunction. Applying a warm, moist compress to closed eyelids can help soften the oils within the meibomian glands, supporting the release of lipids into the tear film. Gentle eyelid hygiene and massage may also be recommended as part of an individual’s dry eye management plan. If symptoms persist despite these measures, a specialist assessment can help identify which treatments may be more appropriate.
What Dry Eye Treatments Are Available at Cathedral Eye Clinic?
For people experiencing persistent dry eyes in winter time, lifestyle changes and over-the-counter eye drops may not provide sufficient relief.
At Cathedral Eye Clinic, our Dry Eye Centre offers a range of treatments designed to address different causes of dry eye disease.
The most appropriate treatment depends on an individual’s symptoms, tear film quality, eyelid health and the underlying factors contributing to their condition.
1. Ocular Lubricants
Ocular lubricants, commonly referred to as artificial tears, help supplement the natural tear film and provide additional moisture to the surface of the eye. They can help relieve symptoms such as dryness, grittiness, burning and irritation. Your clinician can recommend the most appropriate option based on your symptoms. For patients who require frequent application, preservative-free lubricants may be recommended.
2. Eye-Light IPL and LLLT
Eye-Light combines two light-based treatments: Intense Pulsed Light (IPL) and Low-Level Light Therapy (LLLT). These treatments are designed to address aspects of dry eye disease associated with meibomian gland dysfunction and tear film instability.
Intense Pulsed Light (IPL)
IPL uses controlled pulses of light applied to the skin around the eyes. The treatment has been studied for meibomian gland dysfunction, which can affect the oily layer of the tear film and contribute to increased tear evaporation.
Low-Level Light Therapy (LLLT)
LLLT uses low-level light delivered through a specialised device. When combined with IPL, it forms part of a treatment approach designed to improve meibomian gland function and address certain causes of dry eye disease. Your clinician will assess your eyes to determine whether Eye-Light treatment is appropriate for you.
3. Punctal Plugs
Punctal plugs are small devices inserted into the tiny drainage openings located near the inner corners of the eyelids. These openings, known as puncta, allow tears to drain away from the surface of the eyes. By partially or completely blocking this drainage, punctal plugs help retain tears on the ocular surface for longer, potentially improving lubrication and reducing dryness. Punctal plugs are not suitable for every patient, so an assessment is required to determine whether this treatment is appropriate.
4. Tixel
Tixel is another treatment available at Cathedral Eye Clinic for selected patients experiencing dry eye symptoms. It uses controlled thermal energy delivered through a specialised device to the skin around the eyelids. The treatment may help improve the function of the meibomian glands in suitable patients, supporting the oily component of the tear film. As with other dry eye treatments, suitability depends on an individual’s clinical assessment and the underlying cause of their symptoms.
When Should You See an Eye Specialist About Dry Eyes?
Occasional dryness or irritation during colder weather does not necessarily indicate an underlying eye condition. However, if you experience persistent symptoms, frequent watering, ongoing redness or fluctuating vision, it is important to seek professional advice. Dry eye disease can be a long-term condition, and symptoms may come and go depending on environmental conditions and individual circumstances. A specialist assessment can help establish whether your symptoms are associated with reduced tear production, excessive tear evaporation, meibomian gland dysfunction or another contributing factor.
At Cathedral Eye Clinic, your dry eye assessment considers:
- Your symptoms: When they started, how frequently they occur and what makes them better or worse.
- Your tear film: The quality and stability of your tears.
- Your eyelids and meibomian glands: Whether gland dysfunction may be contributing to tear evaporation.
- Your ocular surface: The overall condition of the surface of your eyes.
This information allows our team to recommend an individualised treatment plan, which may involve one treatment or a combination of approaches.
If you experience a painful red eye, significant changes in vision or other sudden eye symptoms, seek prompt medical attention rather than assuming these are caused by dry eye.
