The white portion of the eye (sclera) can appear red when the vessels on the surface become enlarged. This may result from mechanical irritation, environmental irritants (such as extremely dry air, excess sun exposure), allergic reactions, infection, and other medical conditions.
The most common causes of red eyes are allergies, dry eyes, contact lens overwear, and conjunctivitis. Allergies affect 40% of the population. Allergy eye symptoms are caused by inflammation of the eye surface when the immune system overreacts to allergens such as pollen, pet dander, grass, or weeds.
Sometimes it is something as simple as wearing contact lenses for too long, or staring at a computer screen for lengthy periods of time without a break. Other causes include, among others: allergies, blepharitis (inflamed eyelid), conjunctivitis (pink eye), dry eye, eye injury, or glaucoma.
Red eyes are usually nothing to worry about, as long as they don't happen often and don't last long. You might find brief relief in over-the-counter artificial tears that wash and moisten your eyes. Decongestants and antihistamines can help with itchiness and redness because of allergies.
Red eyes are very common and can be caused by allergies, viral infections, or dry eyes. But sometimes they are the result of more serious conditions that need medical attention. In general, reasons to get professional help include severe pain, changes in your vision, or symptoms that keep getting worse.
Yes, stress can contribute to red eyes, although it typically does so indirectly. Your body often produces adrenaline in response to stress, which in turn can lead to tension and dry eyes. As discussed, both tension and dry eyes can contribute to your red eyes.
A red eye is usually nothing to worry about and often gets better on its own. But sometimes it can be serious and you'll need to get medical help.
Lack of sleep decreases oxygen that is available for the eyes; this causes blood vessels to dilate and give the appearance of being red or bloodshot.
If you are experiencing irritation, excess watering, blurred vision, or have the feeling of a foreign body in the eye, it may be the result of dry eyes from dehydration. Rehydrating by drinking plenty of water is one of the best treatments for dry eyes.
Seek emergency medical care
Call 911 or your local emergency number for red eye if: Your vision changes suddenly. It is accompanied by severe headache, eye pain, fever or unusual sensitivity to light. You also experience nausea or vomiting.
Contact your doctor for an appointment if you have red eye that doesn't clear up after several days, especially if you have a thick or nearly continuous pus or mucous discharge.
High blood pressure and red eyes often occur simultaneously. The eyes are full of blood vessels, and they typically stiffen and join each other in instances of high blood pressure. Severe cases can lead to blood leakage and busted blood vessels, which can have many dangerous effects on the vision.
The duration of bloodshot eyes is mostly based on their severity and cause. A subconjunctival haemorrhage typically only lasts for between seven and 10 days. This is the time period for gauging whether it's actually something more severe.
Conclusion The most significant ocular symptom experienced by people suffering from COVID-19 was sore eyes. Other symptoms associated with other types of conjunctivitis, such as mucous discharge and gritty eyes linked to bacterial infection, did not reach significance.

Tired eyes tend to be bloodshot eyes. That's because a lack of sleep can decrease the amount of oxygen that reaches your eyes, which in turn causes blood vessels on them to dilate and appear red.
If caused by dehydration, drinking plenty of water will help flush out salt in the body and properly hydrate your eyes to help reduce eye strain. Resting the eye by blinking or shutting the eye will also help alleviate eye strain. See these tips to help ease the pain of digital eye strain.
Drinking more water can help your body produce a healthy volume of tears, which is important to prevent dry eyes. It's also important to have healthy lacrimal glands to produce tears and oil glands so that the tears don't evaporate too quickly. Beverages containing caffeine or alcohol can be dehydrating.
The saline level of your tears helps to keep your eyes healthy. Washing your eyes with water irritates the ocular surface and can damage the lens cells of your eye. Splashing tap water in your eye puts you at risk of developing a severe eye infection, due to the contaminants that we've already covered.
