Red eyes can be more than just a result of rubbing your eyes too often; they can stem from viral or bacterial infections. These conditions might lead to discomfort and even affect your vision. Are they contagious? Let's delve into the causes of red eyes, their symptoms, and how to manage them.
Viral Conjunctivitis
Pink eye, or viral conjunctivitis, occurs when a virus causes inflammation in the conjunctiva—a thin layer covering the eyelids and the whites of the eyes. While this membrane typically keeps the eyes moist and guards against infections, it can also become infected due to viruses like:
- Adenovirus (causing respiratory infections)
- Herpes simplex virus (causing cold sores or genital herpes)
- Varicella-zoster virus (causing chickenpox)
- Rubella virus (causing measles)
- Picornavirus
Bacterial Conjunctivitis
Another Red Eye Culprit Bacterial conjunctivitis arises when bacteria infect the conjunctiva. This condition is more common in children, the elderly, contact lens wearers, and individuals with weakened immune systems.
Bacteria involved include:
- Haemophilus influenzae (common in children)
- Streptococcus pneumoniae (common in children)
- Moraxella catarrhalis (common in children)
- Staphylococcus (common in adults)
Bacterial conjunctivitis spreads through contact with infected individuals, objects, coughing, sneezing, and respiratory droplets. So, practicing good hygiene is vital.
Wash your hand before touching your eye
Generally, conjunctivitis caused by bacterial infections tends to be more severe than viruses. One's sight could be reduced because of the thick liquid. In rare cases, this type could produce a lot of liquid from the eye with rapid infections.
Symptoms and Differences
Both viral and bacterial conjunctivitis share similar symptoms, including:
- Redness, itchiness, or a burning sensation in one or both eyes
- Clear or watery discharge
- Sensitivity to light
- Feeling like there's a foreign object in the eye
- Morning eye crusts
However, bacterial conjunctivitis may also lead to:
- Green or yellow thick discharge causing eyelids to stick together
- Swollen surface of the eye
- Swollen and painful eyelids
- Decreased vision
Treatment and Prevention
Viral conjunctivitis often resolves on its own. If necessary, patients might use artificial tears, cold compresses, and antiviral medication. Bacterial conjunctivitis can be treated with antibiotics, eye drops, or ointments. Both types are contagious, so care is essential.
Prevent the Spread:
- Avoid touching your eyes with dirty hands
- Wash hands frequently
- Use a clean towel and change pillowcases regularly
- Dispose of expired cosmetics
- Refrain from sharing eye care tools
The red eye could be treated with eye drops
