Preventing Eye Infections

What is an eye infection?

An eye infection is when your eye gets sick because of tiny germs like bacteria, viruses, or fungi. The most common one is pink eye (conjunctivitis). Viruses usually cause pink eye, but bacteria can do it too. Antibiotics, which are medicines that kill bacteria, don’t work on viruses.

Eye infections can happen in one eye or both. Some are not very serious, while others are emergencies that might make you lose vision. These infections can affect different parts of your eye, like the eyelid, conjunctiva, cornea, or other outer parts.

Some Common Eye Infections

  1. Pink Eye (Conjunctivitis): This makes your eye look pink or red. Germs like viruses or bacteria can cause it, and it’s contagious.
  2. Style: This is a small, painful bump on your eyelid. It happens when a tiny oil gland at the base of your eyelash gets clogged.
  3. Blepharitis is when the edges of your eyelids become swollen and irritated. Bacteria or problems with oil glands can cause it.
  4. Corneal Ulcer: This is like a sore on the transparent front part of your eye. An infection can cause it, making your eye red and sensitive to light.
  5. Conjunctivitis (Viral): Another type of pink eye caused by a virus. It’s often linked to a cold or upper respiratory infection.

Causes of Eye Infections

  1. Germs: Tiny bacteria, viruses, and fungi can make your eyes sick.
  2. Dirty Hands: Touching your eyes with dirty hands can bring in germs and cause infections.
  3. Contact Lenses: If you don’t clean or use them right, contact lenses can lead to infections.
  4. Scratches or Injuries: Even small hurts to your eyes can let germs in and cause problems.
  5. Allergies: Pollen or dust can make your eyes itchy and prone to infections.
  6. Old or Dirty Eye Products: Using expired or dirty makeup, eye drops, or other eye stuff can introduce germs and cause infections.

Treatment of Eye Infection

Treating an eye infection involves:

  1. Medicine: Using eye drops or ointments a doctor prescribes to kill germs.
  2. Warm Compress: Putting a warm, clean cloth on your closed eyes can help reduce swelling and discomfort.
  3. Avoiding Irritants: Avoid things that can worsen, like rubbing your eyes or using expired eye products.
  4. Good Hygiene: Wash your hands, avoid sharing towels or makeup, and follow the doctor’s advice for contact lens care.
  5. Rest: Rest your eyes by resting them and avoiding bright lights.

Ways to Prevent Eye Infections

Eye infections can be a pain, causing redness, itchiness, and discomfort. While you can’t eliminate the risk, there are many ways to significantly reduce your chances of getting one. Here are some simple tips you can follow:

1. Hand Hygiene is Key

  • Wash your hands often. This is the golden rule, especially before touching your eyes, putting in contact lenses, or applying makeup. Use soap and water for at least 20 seconds, and remember to scrub under your nails.
  • Avoid touching your eyes. It’s tempting to rub when they itch but resist. Your hands harbor all sorts of germs that can easily infect your eyes.

2. Contact Lens Care

  • Clean and store your lenses properly. Follow your eye doctor’s instructions in the letter. This usually involves using a disinfectant solution and replacing your lens case regularly.
  • Only sleep in your lenses if specifically approved by your doctor. Doing so increases your risk of infection significantly.
  • Don’t use homemade saline solutions or tap water to clean your lenses. Stick to commercially prepared solutions.

3. Makeup and Personal Items

  • Don’t share eye makeup or applicators. This includes mascara, eyeliner, eyeshadow, and brushes. Even sharing with family members is risky.
  • Replace your eye makeup regularly. Most mascaras and eyeliners should be tossed after three months, while eyeshadows and powders can last longer (check the expiration date).
  • Wash your brushes and applicators regularly. Use gentle soap and water, and let them air dry completely.

4. General Good Habits

  • Wear protective eyewear when participating in sports or working with hazardous materials. This helps shield your eyes from dust, debris, and chemicals.
  • Remove makeup thoroughly before bed. Leftover makeup can trap bacteria and irritate your eyes.
  • Get regular eye exams. Your eye doctor can check for early signs of infection and other eye problems.
  • Don’t use expired eye drops or medications. Always check the expiration date before using.
  • Be mindful of allergies. If you have allergies that affect your eyes, avoid triggers and use allergy medications as your doctor prescribes.

What can I expect if I have an eye infection?

If you have an eye infection from allergies, it’s not contagious and won’t harm your sight. You can be around others without worrying. But if viruses, bacteria, or fungi cause your eye infection, it can be spread to other people. In this case, avoiding being close to others is best until you’ve treated it.

Some eye infections, especially those from injuries or affecting the cornea, can be harmful to your vision. That’s why it’s essential to see an eye doctor. They can determine what caused the infection and how to treat it properly.


Preventing eye infections is vital for good eye health. Practicing proper hygiene, taking care of contact lenses, and avoiding sharing personal items can reduce the risk. If you have an eye infection, prompt treatment is crucial. While allergies aren’t contagious, infections from viruses or bacteria can be, so taking precautions is essential.
