Red Eye

A red eye is a common condition characterized by inflammation and reddening of the white part of the eye (sclera) and the inside of the eyelid. It can be caused by various factors, including:

• Infections: Bacterial or viral infections, such as conjunctivitis (pink eye), can cause redness, discharge, and irritation in the eye.
• Allergies: Allergic reactions to substances like pollen, dust, or pet dander can lead to red, itchy, and watery eyes.
• Dry Eye: Inadequate tear production or poor tear quality can cause eye irritation, redness, and dryness.
• Foreign Body: The presence of a foreign object in the eye, such as dust, sand, or an eyelash, can cause redness, discomfort, and tearing.
• Injury: Trauma to the eye, including blunt force or chemical burns, can result in redness, swelling, and pain.
• Other Conditions: Certain medical conditions, such as uveitis, scleritis, or keratitis, can also cause red eyes.

Symptoms

In addition to redness, other symptoms that may accompany a red eye include:

• Itching or burning sensation
• Discharge or crusting on the eyelashes
• Excessive tearing or watery eyes
• Sensitivity to light (photophobia)
• Blurred vision

Treatment and Management

Treatment for a red eye depends on the underlying cause. Some common treatments include:

• Antibiotic ointments or drops: For bacterial infections
• Antiviral medications: For viral infections like herpes simplex

• Lubricating eye drops: To moisturize dry eyes and reduce irritation
