Cold eye stroke: causes, symptoms and remedies to protect eyesight
Low temperatures can affect eye health in ways we often underestimate. Cold eye stroke, an ailment caused by exposure to temperature changes or frigid wind, is more common than we think, especially in the winter months. This problem not only causes temporary discomfort such as irritation and tearing, but can also aggravate pre-existing conditions.
In this article we will delve into the causes, symptoms and most effective remedies to prevent and cope with cold eye stroke, providing practical examples to protect visual health.
What is cold blow to the eye?
Cold eye stroke is a temporary inflammation that occurs when the eyes are exposed to low temperatures or sudden changes in thermal environment. Frigid weather conditions and icy wind can irritate the ocular surface, causing symptoms such as redness, burning and tearing.
The surface of the eye is protected by a layer of tears, which can be compromised in the presence of intense cold or very dry air. This phenomenon is especially common when moving from a warm to a cold environment without adequate protection, as often happens in winter.
Main causes of cold eye stroke
1. Temperature swings
The sudden change from a warm to a cold environment can stress ocular tissues, causing discomfort and irritation. This is especially true in winter, when warm, dry indoor air collides with cold, moist outdoor air.
2. Wind exposure
The cold wind stroke is one of the main culprits of cold stroke. Wind speed amplifies the dispersion of the tear film, leaving the eyes more vulnerable. One example? Doing outdoor sports, such as running or biking, on windy days can cause a burning sensation and excessive tearing.
3. Dry air
Heated indoor air can reduce ambient humidity, causing dry eyes, which makes the eyes more susceptible to cold.
4. Use of contact lenses
Contact lenses can make matters worse, as they can absorb the moisture needed to protect the eyes, amplifying symptoms of dryness and irritation.
Symptoms of cold eye stroke
Cold eye stroke manifests with noticeable symptoms that can temporarily impair visual quality and ocular well-being. Some of the most common include:
- Redness: Low temperatures and wind cause dilation of blood vessels in the sclera, making the eyes visibly red. This reaction is a sign of irritation of the ocular surface.
- Burning: The burning sensation is often accompanied by a perception of heat and discomfort on the surface of the eyes. This phenomenon occurs because the cold compromises the tear film, leaving the cornea more exposed.
- Excessive tearing: When the tear film becomes altered, the body reacts by producing an excessive amount of tears in an attempt to restore hydration. This symptom is common after prolonged exposure to cold or wind.
- Dryness: Impairment of the protective tear layer causes a feeling of sand in the eyes, which may be accompanied by itching or mild irritation.
- Blurred vision: Excessive tearing or irritation of the cornea may interfere with vision, causing temporary difficulty in focusing.
These symptoms frequently occur during outdoor activities in winter, such as a day of skiing or a long walk without proper eye protection.
Remedies for cold eye stroke
Intervening promptly at the first signs of cold eye stroke is essential to relieve discomfort and prevent complications. Here are the most effective remedies:
Moisturizing eye drops
Artificial tear drops are one of the simplest and most immediate remedies to restore hydration to the ocular surface. It is important to choose preservative-free formulations, which are gentler for sensitive eyes and can be used several times a day. Regular application protects the ocular surface, improving its comfort during cold exposure.
Hot packs
Warm compresses are a natural way to reduce dry eyes and stimulate the function of the tear glands. Applying a warm cloth to the eyes for a few minutes relaxes the eye muscles and promotes circulation in the eye area. This remedy is especially good after exposure to cold weather to relieve burning and sandy feeling in the eyes.
Protection with goggles
Wrap-around or sport sunglasses are not only useful in summer: even during winter they protect the eyes from wind and light reflections off snow. Polarized lenses also reduce glare, improving vision and visual comfort. Wearing protective eyewear is essential for those who play outdoor sports or spend many hours in cold, windy environments.
Humidify environments
Another factor contributing to eye discomfort during the winter months is dry air produced by heating systems. Using a humidifier indoors helps maintain an optimal humidity level, reducing the likelihood of dry eyes. This expedient is especially useful for those who spend a lot of time indoors or in the office.
Prevention of cold eye stroke
Preventing cold eye stroke is possible by following a few simple precautions, which protect visual health during the winter season.
- Wear protective goggles: Using wrap-around or sports goggles is the first line of defense against wind and cold. These accessories create a barrier that reduces the direct impact of low temperatures on the ocular surface.
- Apply preventive eye drops: Before going out in the cold, using artificial tears helps keep the tear film well hydrated and stable, preventing dryness and irritation.
- Avoid temperature changes: Protect your eyes with a scarf or visor hat when you go from hot to cold environments. In this way, you reduce the impact of sudden temperature changes on the ocular surface.
- Maintain good hydration: Drinking plenty of water helps ensure optimal hydration not only for the body, but also for the eyes. This shrewdness is critical to maintaining an effective tear film that can protect the ocular surface.
When to consult a doctor for cold eye stroke?
If symptoms persist for more than 48 hours or if you notice worsening, such as intense pain or vision loss, it is important to contact an ophthalmologist. Specific treatments may be needed to avoid complications.
