Red Eyes Causes Symptoms Diagnosis and Treatment Guide
Red eyes (aankhon ka laal hona) happen when the blood vessels on the surface of your eye become wider and more visible. This can affect one eye or both eyes. Redness is very common and usually mild, but in some cases it can be a sign of an eye problem that needs treatment. Some people also call this bloodshot eyes.
- Visible redness in the white part of the eye (aankh safed hisse mein laal)
- Itching (khujli)
- Burning or stinging (jalan)
- Watering (paani aana)
- Discharge or crusting (discharge ya paapdi jamna)
- Sensitivity to light (roshni se takleef)
- Mild pain or discomfort (halka dard)
- Swelling around the eye (aankhon ke aas paas sujan)
What Are Red Eyes
Red eyes (laal aankhen) happen when the small blood vessels on the surface of the eye widen (blood vessels phailna). This makes the white part of the eye look pink or red instead of white. It can happen suddenly or build up slowly over a day.
Red eyes without pain are usually mild and settle on their own. Redness with pain, vision changes, or light sensitivity needs prompt medical attention. Red eyes (laal aankhon ki problem) can affect just one eye or both eyes at the same time.
Why Do Red Eyes Happen
Red eyes (aankhon ka laal hona) can occur for several reasons. Identifying the cause helps guide the right treatment (sahi treatment).
Red Eyes Due to Dry Eye
When the eye does not have enough tears (aansu ki kami), the surface becomes dry (sookhapan). This dryness irritates the eye and causes redness (laalpan).
Red Eyes Due to Allergy
Allergies (allergy problem) can cause itching (khujli), watering (paani aana), and swelling (sujan). The eyes often turn red along with these symptoms, especially during pollen or dust season.
Eye Infection (Conjunctivitis)
Infections such as conjunctivitis (aankh aana) are a common cause of red eyes. They can cause discharge (discharge), crusting (paapdi jamna), and redness, and may spread from one eye to the other. Cases rise sharply after the monsoon in Noida, Greater Noida, and Delhi, when warm and humid conditions help viruses and bacteria spread faster in schools, offices, and homes.
Dust, Smoke or Pollution
Dust (dhool), smoke (dhuaan), or pollution can irritate the surface of the eye. This is a common cause of red eyes in areas with high pollution levels. In Delhi NCR, air quality drops sharply between October and January, and fine dust particles settle on the eye surface through the day, causing burning and redness that is often worse outdoors and improves indoors.
Contact Lens Use
Wearing contact lenses for too long or not cleaning them properly (lens ki safai na karna) can irritate the eye and lead to redness.
Chemical or Water Exposure
Synthetic colours during Holi can irritate the eyes and cause redness if they get into the eye. Swimming pool chlorine is another common local trigger. If redness continues for more than a day after swimming, or if there is discharge, it should be checked to rule out infection.
Broken Blood Vessel
Sometimes a small blood vessel on the surface of the eye breaks (blood vessel phatna). This causes a bright red patch. It usually looks worse than it feels, is painless, and often clears on its own.
Underlying Eye Conditions
In some cases, redness can be linked to more serious conditions such as uveitis or glaucoma (glaucoma problem). These usually come with pain (dard) or vision changes (dhundhla dikhna) along with the redness, and are part of when to worry about red eyes.
How Doctors Diagnose Red Eyes
An eye doctor (aankhon ke doctor) will examine your eyes carefully to find the cause of the redness.
Tests may include:
- Examining the surface of the eye (eye checkup)
- Checking vision (vision test)
- Measuring eye pressure (eye pressure test)
- Testing for infection (infection test) or allergy
- Asking about symptoms, contact lens use, and recent exposure to dust, colour, or pool water
How to Treat Red Eyes
Treatment (red eyes ka treatment) depends on the underlying cause.
Treating Dry Eye
Lubricating eye drops (eye drops) can help if dryness (sookhapan) is causing the redness.
Allergy Treatment
Antihistamine eye drops (allergy eye drops) or allergy medicine (allergy medicine) can reduce itching and redness.
Managing Infection
If an infection (infection problem) is present, antibiotic or antiviral drops may be prescribed by the doctor.
Avoiding Irritants
Reducing exposure to dust (dhool), smoke (dhuaan), and pollution can help the redness settle. Protective glasses (protective chashma) can be worn outdoors, especially during high pollution months.
Caring for a Broken Blood Vessel
Most broken blood vessels (blood vessel phatna) need no treatment and clear on their own within one to two weeks.
Treating Serious Conditions
If the cause is a deeper eye condition such as uveitis or glaucoma (glaucoma problem), the doctor may prescribe specific medication or further treatment.
Can Red Eyes Be Prevented
Some causes cannot be prevented. However, you can reduce the risk by:
- Managing allergies early (allergy ka treatment)
- Practicing good eye hygiene (aankhon ki safai)
- Taking screen breaks (screen se break)
- Avoiding polluted environments, especially between October and January (pollution se bachav)
- Wearing protective glasses during Holi and swimming goggles in the pool
- Cleaning contact lenses properly (lens ki safai)
- Getting regular eye checkups (regular eye checkup)
Early care helps prevent long term problems (lambe samay ki problem).
