Common Causes of Bacterial Eye Infections

Advice and Support from Layanson Pharmacy, Pontypool

Bacterial eye infections, commonly referred to as conjunctivitis, occur when the thin membrane covering the white part of your eye (the conjunctiva) becomes inflamed and irritated. This condition is often called “red eye” and can affect one or both eyes, sometimes spreading within hours.

There are different types of conjunctivitis, including infective (caused by bacteria or viruses) and allergic (triggered by allergens such as pollen or dust mites). It can also result from contact with irritants, like shampoo, chlorinated water, or even a loose eyelash.

What Causes Bacterial Eye Infections?

Bacterial conjunctivitis can spread easily through:

• Direct contact with infected hands or objects (e.g., towels, makeup)
• Poor hand hygiene
• Wearing contaminated contact lenses
• Sharing personal items like pillows or face cloths

Viral and allergic forms may result from colds, hay fever, or exposure to irritants.

When Should You Seek Medical Attention?

While many cases of bacterial conjunctivitis are mild and resolve on their own, you should consult a pharmacist or GP if:

• You wear contact lenses and develop symptoms
• The infection doesn’t improve within a few days
• You notice blurred vision, intense pain, or light sensitivity
• The eye produces thick yellow or green discharge

At Layanson Pharmacy, our team can help you determine the cause and offer appropriate treatment or refer you to your GP if needed.

How to Treat a Bacterial Eye Infection

Treatment depends on the type of infection:

• Bacterial conjunctivitis is usually treated with antibiotic eye drops or ointments, which can clear the infection in a few days to a week.
• Viral conjunctivitis typically doesn’t require medication — your body will fight it off naturally. In the meantime, applying a cool, damp cloth can help relieve discomfort.
• For irritant-related or allergic conjunctivitis, avoiding the trigger and using antihistamines or soothing eye drops can help manage symptoms.

If you’re unsure which treatment is right for you, speak to one of our pharmacists at Layanson Pharmacy. We’ll guide you to the most effective relief and help you manage your symptoms properly.

How to Avoid Contracting Conjunctivitis

To reduce your risk of developing or spreading infective conjunctivitis:

• Wash your hands frequently
• Avoid rubbing or touching your eyes
• Don’t share towels, makeup, or pillows
• Clean and replace your contact lenses as advised
• Replace makeup products after an infection to avoid reinfection

If you currently have conjunctivitis, it’s best to stop wearing contact lenses until your symptoms are gone. Once recovered, be sure to use a fresh pair.
