Eye fatigue is a common phenomenon in modern society, mainly due to our intensive use of screens. One of the most common symptoms of this fatigue is the appearance of redness in the eyes. Although it's not always a sign of a serious problem, red, tired eyes can affect your daily well-being. Here are a few tips on how to keep your eyes healthy and avoid these discomforts.
Understanding eye fatigue
Eye fatigue generally occurs after prolonged activities requiring intense visual concentration, such as working on a computer, reading, or even driving long distances. Red eyes, often accompanied by stinging, dryness or blurred vision, are classic signs of eyestrain. This condition is also known as "computer vision syndrome."
Causes of red and tired eyes
Red eyes can be caused by various factors linked to eye fatigue:
- Dry eyes: We blink less when we concentrate on a screen, which reduces tear production and causes dry eyes.
- Light overload: Prolonged exposure to intense blue light from screens can irritate the eyes.
- Lack of sleep: Insufficient sleep does not allow your eyes to rest sufficiently, increasing the likelihood of fatigue and redness.
- Dehydration: A lack of hydration can also contribute to dry, irritated eyes.
Tips to prevent and relieve red eyes and eye fatigue
- Adopt the 20-20-20 rule: To reduce eyestrain, apply the 20-20-20 rule: every 20 minutes, look at an object 20 feet (about 6 metres) away from you for 20 seconds. This allows your eyes to rest and rehydrate naturally.
- Arrange your workspace: Make sure your screen is about 50-70 cm from your eyes and slightly below eye level. If necessary, reduce glare by adjusting the ambient lighting and using an anti-glare filter.
- Use artificial tears: Eye drops can help relieve dry, irritated eyes. Choose preservative-free artificial tears for frequent use.
- Regulate your exposure to blue light: Use glasses with an anti-blue light filter or activate the night mode on your devices to reduce the impact of blue light on your eyes, especially at the end of the day.
- Ensure you're well hydrated: Drink enough water throughout the day to maintain good body hydration, including your eyes.
- Get enough sleep: Quality sleep is essential for eye health. To allow your eyes to rest fully, sleep between 7 and 8 hours a night.
When should you consult a professional?
If red eyes persist despite following these tips, or if they are accompanied by pain, changes in vision or eye discharges, it is important to consult an optometrist. These symptoms could indicate a more serious eye condition requiring professional treatment.
Eye strain and red eyes are common complaints, but they can be avoided or reduced with simple, effective habits. By taking care of your eyes daily, you can not only improve your visual comfort but also prevent potential long-term eye health problems. Remember, your eyes are precious: take care of them!
