Red eyes are a common occurrence, with many of us experiencing at some point in our lives. While red eyes are often associated with factors like allergies, eye infections, or irritants, one of the most frequent causes of red eyes, particularly in today’s fast-paced life, is fatigue. The connection between fatigue and red eyes might not be immediately obvious, but understanding it can help individuals take proactive steps to protect their eyes and overall well-being.
Here in this post, we will explain how fatigue contributes to red eyes, the science behind it, the symptoms, and ways to prevent and manage this condition.
What is a red eye?
Before diving into how fatigue causes red eyes, it’s important to first understand what happens when the eyes appear red. Red eyes occur when the blood vessels in the eyes become dilated or inflamed. This can be caused by a range of factors, from dry eyes to allergies or more serious underlying conditions. The blood vessels in the white part of the eye, that is the sclera, expand, and when irritated or inflamed, they can give the eye a reddish or bloodshot appearance.
Typically, the whites of our eyes are clear, and the blood vessels are hardly noticeable. However, when these vessels become irritated due to various causes, the eyes appear red. Fatigue is one of the leading contributors to this change. Underlying causes could be one of the reasons for red eyes in some cases, but in today’s lifestyle and work culture, fatigue is one of the most obvious reasons for red eyes.
The science behind fatigue and red eyes
Fatigue can affect the eyes in numerous ways. Below are the key mechanisms by which tiredness leads to red eyes:
Reduced tear production. When you are tired, your body’s systems, including the tear production system, start to function less efficiently. Normally, the tear glands in your eyes produce a thin layer of tears that keep your eyes moist and comfortable. Fatigue can reduce this tear production, leading to dry eyes. When eyes become dry, the blood vessels in the eyes can become irritated and dilated, resulting in red eyes. This is particularly common in people who spend long digital screen time, less blinking, stitching work or long driving etc.
Increased eye strain. When you’re tired, your eyes have to work harder to focus and maintain clarity. This increased strain can cause discomfort and lead to the dilation of blood vessels. Eye strain is often exacerbated by activities that require prolonged focus, such as reading, stiching, fireworks, working on a digital medium such as on a computer, or watching mobile phone or TV. The more tired you are, the harder your eyes have to work to stay focused, and the greater the strain. This, in turn, can lead to redness, as the blood vessels become more pronounced due to the strain.
Sleep deprivation and blood flow. Sleep deprivation has a direct impact on the body’s circulation, including the eyes. When you don’t get enough sleep, the body is deprived of the opportunity to regenerate and rest. As a result, blood flow can become more sluggish. This can contribute to the dilation of blood vessels in the eyes, making them appear redder than usual. Sleep deprivation also leads to general fatigue, which increases the likelihood of eye irritation and dryness.
Allergic reactions. Fatigue can also amplify allergic reactions. When you are tired, your body’s ability to manage allergens effectively diminishes. This means that your eyes are more likely to react to allergens, such as pollen or dust, causing them to become red, itchy, and inflamed. Fatigue exacerbates the impact of allergens, making red eyes more prevalent in people who are sensitive to them.
Symptoms
Red eyes caused by fatigue come with some common symptoms that are important to recognize:
Bloodshot eyes. The most obvious sign is the redness of the eyes, with blood vessels in the sclera becoming enlarged and prominent.
Gritty feeling. Fatigued eyes often feel dry, as the tear production system isn’t functioning optimally. This can create a sensation of grittiness.
Eye strain. Along with red eyes, fatigue-induced eye strain may result in a feeling of heaviness or discomfort in the eyes.
Blurred vision. Focusing can become more difficult when eyes are exhausted.
Sensitivity to light. Eyes that are fatigued can become more sensitive to light called photophobia, making it uncomfortable to be in bright environments.
Watery eyes. While dryness is common, sometimes the irritation can cause the eyes to water excessively as the body attempts to compensate for the lack of moisture.
Prevention and care
Fortunately, there are several steps that individuals can take to prevent and alleviate red eyes caused by fatigue. Let’s explore some of these handy solutions:
1. Ensure proper sleep
One of the most effective ways to reduce red eyes from fatigue is to get adequate rest. Adults need between 7 to 8 hours of sound sleep each night to allow the body and eyes to regenerate. Good sleep promotes better circulation, tear production, and immune function, reducing the likelihood of red eyes.
2. Artificial tears
Dry eyes caused by fatigue can be alleviated by using over-the-counter artificial tears. These lubricating eye drops can provide temporary relief from the dryness and irritation that contributes to red eyes.
3. Stay hydrated
Dehydration can exacerbate dry eyes. Drinking plenty of water throughout the day ensures that your body remains hydrated and your eyes are less prone to irritation.
4. Take regular breaks
If you are working long hours in front of a computer or reading, make it a habit to take breaks every 30 to 60 minutes. Shift your sight to nature, walk around, close your eyes for a while, try blinking exercise, and rest your eyes by looking at distant objects.
5. Redness reliever drops
For quick relief from eye redness due to fatigue from long driving, digital screen use, conjunctivitis, or foreign particles, gently wash your eyes and instill 2 drops of Eyespa red eye drops and relax for a few minutes with closed eyes. It will relax your eyes, reduce the redness, and comfort the sore eyes. The key ingredient, naphazoline, is a clinically studied molecule for eye redness, which is safe to use.
6. Eye splash
In general, in the morning when we woke up, we washed our face and eyes. But it's not enough; flushing out the eyes multiple times in a day keeps the eyes clean, cool, and relaxed. Remember, eyes are very delicate; therefore, be cautious that you are not splashing water in the eyes too hard. Be gentle every time you splash. Try flushing your eyes once in the morning after waking up, once before bedtime, and 3 to 4 times during the day.
7. Adjust screen-brightness
Too bright or dim screen can put pressure on the eyes. Therefore adjusting screen brightness or lighting is crucial. Poor lighting can worsen eye strain. Ensure that the area where you work or read is well-lit, and try to avoid glare on your computer screen. If you work at night, consider using softer lighting to reduce the strain on your eyes. May keep the screen in dark mode or eye shield mode.
If your red eyes persist, it’s advised to visit an ophthalmologist. They can help determine if your red eyes are caused by fatigue or if there are underlying issues such as infections, allergies, or other eye conditions.
Red eyes due to fatigue are a common and often overlooked issue, especially in our modern, technology-driven world. Understanding the connection between fatigue and red eyes is crucial for taking steps to protect eye health.Taking care of your eyes today can ensure that they remain healthy for years to come. So, the next time you find your eyes turning red after a long day, remember that your body is simply signaling that it needs some rest.
