Common Causes of Eye Infections and What to Do About Them

Our eyes are precious windows to the world, allowing us to perceive its beauty and wonder. When eye infections strike, they can cloud our vision and cause discomfort. Here are a few common causes of eye infections.

Poor Hygiene

Maintaining good hygiene is essential for overall health, and this extends to our eyes. Poor hygiene practices can lead to eye infections. When we neglect to wash our hands regularly or use dirty contact lenses, we expose our eyes to harmful bacteria and microorganisms. These pathogens can easily find their way into our eyes, causing infections. Wash your hands thoroughly with soap and water before touching your eyes or handling contact lenses. This simple act can prevent the transfer of harmful germs to your eyes. If you wear contact lenses, make sure to clean and disinfect them according to your eye care professional’s instructions. Replace them as recommended to avoid bacterial buildup. Refrain from touching or rubbing your eyes, especially with unwashed hands. Rubbing can introduce bacteria and irritants, increasing the risk of infection.

Dry Eyes

Dry eyes can be not only uncomfortable but also a contributing factor to eye infections. Tears are essential for maintaining eye health, as they provide lubrication and protection. A lack of tears means the dust and allergens in your eyes don’t get washed out. Drink plenty of water to maintain overall hydration, which can help in the production of tears. Remember to blink regularly, especially when using digital devices for extended periods. Blinking helps distribute tears across the eye’s surface. Use over-the-counter artificial tears or lubricating eye drops to relieve dryness and provide temporary relief. Consider using a humidifier in your living space to maintain adequate humidity levels, which can prevent excessive evaporation of tears. If you wear contact lenses, take out your lenses at night and clean them regularly. Consider wearing sunglasses when outdoors to help protect the eyes from irritants like dust and pollen.


Viruses can pose a significant threat to our eye health and lead to infections. Infections like conjunctivitis, commonly known as pink eye, can be caused by viruses such as adenovirus. These infections are highly contagious and can spread through contact with infected eye secretions.  As mentioned earlier, proper handwashing is crucial. Avoid touching your face, especially your eyes, with unwashed hands. If someone you know has a viral eye infection, avoid close contact with them, and don’t share personal items like towels or pillowcases. Cover your mouth and nose when coughing or sneezing to prevent respiratory viruses from reaching your eyes. If you suspect a viral eye infection, seek prompt medical attention. Viral infections may require specific treatments to prevent complications. Bacteria can also cause eye infections. Bacterial conjunctivitis is caused by different strains of bacteria and spreads through contact with infected secretions or contaminated objects. Proper hygiene is essential to prevent the spread of bacterial eye infections.

Safeguarding your eye health is vital for maintaining clear and comfortable vision. By adhering to good hygiene habits, addressing dry eye symptoms, and taking preventive measures against viral infections, you can protect your eyes from harm and ensure they continue to serve as your windows to the world.
