Red Eye
Red eye is a common condition where the white part of the eye (sclera) appears red or bloodshot due to the enlargement of blood vessels. While it is often a mild and temporary issue, red eye can sometimes be an indicator of an underlying health concern. It can occur in one or both eyes and may be accompanied by irritation, discomfort, or vision problems. If you are experiencing red eyes, it's important to understand the potential causes, recognise the symptoms, and take the right steps for treatment.
Causes of Red Eye
Red eye can be caused by various factors, ranging from simple irritants to more serious medical conditions. Common causes include:
Allergies
Pollen, dust, pet dander, or other allergens can cause inflammation in the eyes.
Dry Eye Syndrome
Insufficient lubrication of the eye can cause redness, irritation, and discomfort.
Infections
Conjunctivitis (pink eye) and other eye infections can lead to red eyes, often with discharge.
Contact Lens Irritation
Improper use or cleaning of contact lenses can cause redness and dryness in the eyes.
Eye Strain
Prolonged screen time, reading, or lack of sleep can lead to eye fatigue, causing the eyes to appear red.
Trauma, Injury & Medical Conditions
Any physical injury to the eye or eyelid can lead to redness and swelling. Conditions like glaucoma, uveitis, or blepharitis can contribute to red eye.
Symptoms of Red Eye
The symptoms that accompany red eye may vary depending on the underlying cause, but common signs include:
- Red or bloodshot appearance in one or both eyes
- Dryness or grittiness in the eyes
- Irritation or itching
- Watery eyes
- Discharge (clear or thick)
- Sensitivity to light (photophobia)
- Pain or tenderness around the eyes
- Blurry vision (in severe cases)
Treatment of Red Eye
The appropriate treatment for red eye will depend on its cause. Some common treatments include:
- Artificial Tears: For dry eye or allergy-induced redness, lubricating eye drops can provide relief and reduce inflammation.
- Antihistamines: If allergies are the cause, over-the-counter antihistamine eye drops or oral medication can help alleviate symptoms.
- Antibiotics or Antivirals: If the redness is due to an eye infection (like conjunctivitis), your optometrist may prescribe eye drops or oral medication to treat the infection.
- Cold Compress: Applying a cold compress to the eyes can reduce swelling and redness, especially for irritated or tired eyes.
- Discontinuing Contact Lens Use: If your red eyes are related to contact lenses, stopping their use and consulting an optometrist is essential for proper care.
- Medical Intervention: In more serious cases, such as with conditions like glaucoma, uveitis, or trauma, your optometrist or doctor may suggest specialized treatment or referral to a specialist.
Prevention of Red Eye
While red eye cannot always be prevented, there are steps you can take to minimize its occurrence:
- Use Proper Eye Protection: Wear sunglasses to protect your eyes from UV rays and irritants like wind or dust.
- Take Breaks from Screens: Follow the 20-20-20 rule to avoid eye strain. Every 20 minutes, look at something 20 feet away for 20 seconds.
- Practice Good Hygiene: Wash your hands regularly, especially before touching your eyes, to prevent infections.
- Avoid Allergens: Limit exposure to known allergens like pollen, dust, and pet dander.
- Proper Contact Lens Care: Always follow the guidelines for cleaning, storing, and wearing contact lenses.
- Stay Hydrated: Drinking enough water helps prevent dry eyes and supports overall eye health.
- Get Regular Eye Exams: Routine eye exams with an optometrist can catch issues early and prevent more severe problems.
