Eye redness

Eye redness is a condition where the white part of the eye (the sclera) has become reddened or "bloodshot." This can occur due to many reasons, including infection, inflammation, allergy, or trauma to the eye.

Causes

Eye redness can be caused by a variety of conditions. These include:

• Conjunctivitis: This is an inflammation or infection of the conjunctiva, the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye.
• Dry eyes: This condition occurs when the eyes do not produce enough tears or the tears evaporate too quickly.
• Allergies: Allergic reactions can cause redness in the eyes. Common allergens include pollen, dust, and pet dander.
• Subconjunctival hemorrhage: This is a bright red patch appearing in the white of the eye. This occurs when a tiny blood vessel breaks just underneath the surface of the eye.

Symptoms

The main symptom of eye redness is an eye that appears red or bloodshot. Other symptoms can include:

• Eye pain
• Eye discharge
• Itching
• Tearing
• Vision changes

Treatment

Treatment for eye redness depends on its cause. Some treatments include:

• Antibiotics: If the redness is caused by an infection, antibiotics may be prescribed.
• Artificial tears: These can be used to treat dry eyes.
• Antihistamines: These can be used to treat allergies.
• Cold compresses: These can help to reduce inflammation and soothe the eye.

Prevention

Prevention of eye redness includes:

• Avoiding allergens
• Using protective eyewear
• Keeping the eyes clean
