Red eyes can show up in a few ways. Maybe your eyes look a little pink overall. Maybe you see visible red veins. Or maybe there’s a dramatic red blotch that wasn’t there yesterday. In most cases, red eyes aren’t a reason to panic—but they shouldn’t be ignored either.
Sometimes it’s just irritation. Other times, it can be a sign of a more serious condition. So how do you know when it’s time to rest your eyes and when it’s time to call your doctor?
Let’s take a closer look at what causes red eyes and how to handle them.
What Causes Red or Bloodshot Eyes?
When the tiny blood vessels in the eye become irritated or swollen, they become more visible. This gives the sclera (the white part of your eye) a red or pink appearance. Redness may show up with other symptoms like itchiness, burning, tearing, or blurred vision.
There are many possible causes for red eyes. Some are mild and temporary. Others require treatment from an eye care provider. Irritants in the environment, such as smoke or dust, can lead to redness, while more serious conditions like glaucoma or uveitis need medical care.
If you’re not sure what’s behind your red eyes, the safest option is to check with your eye doctor. They can pinpoint the cause and recommend the right treatment.
Could Allergies Be the Reason?
If your red eyes come with itchiness and watering, allergies might be to blame. Pollen, pet dander, dust mites, and even strong fragrances can all irritate the eyes.
Allergy-related eye redness tends to come and go with your exposure to the allergen. Antihistamines or allergy eye drops may help relieve the redness and itching.
While allergies are usually not serious, they can affect your quality of life. If your symptoms happen often, talk to your doctor about allergy testing or long-term management strategies.
Dry Eyes and Redness
Dry eye syndrome happens when your eyes don’t produce enough quality tears. Without proper moisture, your eyes can become red, tired, and inflamed.
Prolonged screen time, certain medications, or wearing contacts too long can all make dry eyes worse. Artificial tears or prescription drops can help restore balance and reduce redness over time.
Chronic dry eye can become more than just a nuisance. Over time, it may lead to damage on the surface of the eye, making it even more important to address early symptoms before they escalate.
Are Contact Lenses Making It Worse?
If you wear contacts and notice red eyes, your lenses might be the cause. Wearing them too long, sleeping in them, or using the wrong cleaning solution can all trigger inflammation.
Your eyes may be signaling that they need a break. Try switching to glasses for a day or two and see if the redness improves. If not, check in with your eye doctor.
In some cases, your eyes might be reacting to the lens material itself or the preservative in your contact lens solution. A switch to daily disposables or preservative-free solutions might be all it takes to solve the problem.
Daily Disposable Contact Lenses to Consider:
- 1-Day Acuvue Moist – Gentle on eyes, with added hydration support
- Dailies Total1 – Water-gradient design for all-day comfort
- MyDay Daily Disposable – Soft silicone hydrogel option with high oxygen flow
- Biotrue ONEday – Matches natural tear pH and moisture balance
- Precision1 – A great option for first-time daily wearers

Redness from Eye Infections
Some infections can make the eyes turn red quickly. These infections often come with other symptoms like swelling, discharge, or a gritty sensation.
Two of the most common are conjunctivitis (pink eye) and blepharitis. Conjunctivitis is often contagious and caused by bacteria or viruses. Blepharitis, on the other hand, is a chronic inflammation of the eyelid and is not contagious. Both may require medication.
It’s important not to self-diagnose or use leftover medications for red eyes. What works for one type of infection may not work for another—and could even make things worse.
Eye Injuries and Redness
Even a small injury can cause eye redness. A corneal abrasion, or scratch on the eye’s surface, is a common cause. These injuries can be painful and make the eyes water or become extra sensitive to light.
Other injuries, like being hit in the eye or rubbing too hard, can lead to broken blood vessels. Any trauma to the eye should be taken seriously, even if the redness doesn’t hurt much.
When dealing with eye injuries, avoid trying to treat the problem yourself. Always consult a professional, especially if the injury was caused by a foreign object or chemical exposure.
Is Eye Strain to Blame?
Red eyes after hours of computer work, reading, or driving could be from eye strain. When you don’t blink enough or focus for too long, your eyes can get dry and irritated.
Using the 20-20-20 rule—every 20 minutes, look at something 20 feet away for 20 seconds—can help reduce strain. Also, remember to blink often and use artificial tears if needed.
Eye strain is common, especially with increased screen time. But if you find it happening regularly, it may be worth reviewing your screen habits, lighting, and prescription.
Red Eye Emergencies
Most cases of red eye are mild. But in some situations, redness can point to a serious issue that needs urgent medical care.
Seek immediate attention if you experience red eyes along with:
- Severe pain
- Sudden blurry vision or vision loss
- Light sensitivity
- Intense headache or nausea
These could be signs of acute conditions like glaucoma or uveitis. Don’t wait to get checked.
Other Common Conditions That Cause Red Eyes
Redness can also stem from less common but equally important eye issues. These may not always hurt but still need attention.
A stye or chalazion can cause swelling and redness near the eyelid. A subconjunctival hemorrhage looks like a red blotch on the eye’s surface and usually goes away on its own. Uveitis, an inflammation inside the eye, is more serious and can affect vision if not treated.
If you’re seeing a red patch that appeared suddenly or experiencing ongoing discomfort, don’t wait it out. Always get unusual eye symptoms checked to rule out serious conditions.
How to Treat Red Eyes at Home
If your red eyes are mild, there are a few things you can try to ease the symptoms and help your eyes recover.
- Use artificial tears or preservative-free eye drops.
- Apply a cold or warm compress to your closed eyelids.
- Rest your eyes and avoid screens when possible.
- Stop wearing contacts until the redness clears up.
- Avoid rubbing your eyes—it can make things worse.
Home remedies can bring temporary relief. But if the redness sticks around or gets worse, it’s time to call your doctor.
Take Red Eyes Seriously
Red eyes can seem harmless, but they’re still a signal that something’s not right. Whether it’s allergies, an infection, or eye strain, getting the right care can help prevent more serious problems down the road.
When in doubt, don’t guess. Let an eye doctor check things out and guide you toward the best solution for your eyes.
Your eye health matters, and sometimes even small symptoms can be a sign of something bigger. It’s always worth getting clarity—literally and figuratively.
FAQs
Can red eyes go away on their own?
Yes, if the redness is caused by irritation, mild dryness, or a broken blood vessel, it often goes away without treatment in a few days.
Are red eyes always a sign of infection?
No. Redness can result from allergies, dryness, fatigue, or other non-infectious causes. An exam can help confirm the reason.
Can I still wear contacts if my eyes are red?
It’s best to take a break from contacts until your eyes feel and look better. Wearing them while your eyes are inflamed can make things worse.
What eye drops are safe for red eyes?
Artificial tears are generally safe. Avoid drops that “get the red out” unless your doctor recommends them, as they can sometimes make symptoms worse over time.
When should I go to the ER for red eyes?
If red eyes come with vision changes, intense pain, or nausea, go to the emergency room or see an eye specialist right away.
