5 Of The Most Common Eye Infections And How To Avoid Getting Them

You use them from the moment you wake up to the moment you go to bed but are you really giving your eyes the attention they deserve?

Think of how many objects you touch in a day. Door handles, cash machines, keyboards, railings, phones, and shopping baskets; all of these objects carry germs. Now think about how many times you touch your face in a day. Germs can easily pass from your hands to your eyes and can cause a number of health problems and eye infections. Not only that, your eyes are protected by mucous membranes, moist tissue that can easily collect dirt and germs, so they’re a great place for bacteria to grow. If you shake someone’s hand and then you rub your eyes, you’re transmitting those germs and there’s a good chance you can catch whatever virus they’ve got.


Eye infections can be bacterial, viral, or fungal. People who wear contact lenses are more at risk to eye infections due to the decrease in oxygen reaching their corneas and bacterial or fungal buildup caused by failure to properly disinfect their contact lenses.

5 Common eye infections from bacteria include:

1. Conjunctivitis

This is by far, the number one type of eye infection caused by bacteria. Also known as pink eye, the infection enters through the conjunctiva (the thin membrane that coats the whites of the eye). Symptoms include a red eye, with a watery discharge that can make your eyes stick together. Conjunctivitis spreads easily so it’s important to take precautions if you or anyone you live with has this infection.

2. Corneal Bacterial Infections: Staph and Strep

Corneal infections, also known as keratitis, enter your eye through the cornea, the clear globe at the front of the eye. The cornea is usually quite resilient to disease but occasionally certain bacteria and viruses manage to enter because it is torn or injured in some way. You may get staph or strep infections when your eye comes into contact with contaminated objects (e.g. dirty contact lens) or you may catch an infection from contact with another person. These types of infection can be painful. Your eyes will become red and your vision might become blurry. If left untreated, it can lead to scarring so see an ophthalmologist who will subscribe you antibacterial eye drops.

3. Stye

A stye is a bump on the eyelid that occurs when bacteria from your skin get into the hair follicle of an eyelash. Styes are usually caused by a staphylococcal infection but often get better without any treatment, particularly after they burst. Symptoms may include tenderness, redness and swelling.

4. Blepharitis

Blepharitis is inflammation of the eyelids and symptoms include burning, itching, swelling and blurred vision. Common causes include problems with the oil glands at the base of the eyelids, infections or other skin conditions. Severe cases may require antibiotics or steroids but for most, good eyelid hygiene and frequent cleaning should clear the infection up.

5. Corneal Ulcer

Bacteria, viruses or fungus can cause a corneal ulcer. This is a small crater at the front part of the eye, usually resulting from an infection. People who wear contact lenses are more prone to corneal ulcers as the virus may get trapped behind the lens. Symptoms include redness, feeling as if there is something in the eye, sensitivity to light and blurry vision. If you experience these symptoms, see your ophthalmologist who will be able to provide you antibiotics.

How to prevent getting bacteria and germs in your eyes

Taking care of your eyes is just as important as taking care of any other part of your body. Here are 7 ways you can prevent bacteria and germs getting into the eyes:

  1. Wash hands thoroughly and often.cleaning hands
  2. Avoid touching your face and eyes. If you need to apply make up around your eyes, wash your hands before and after application - and never share makeup.
  3. Where possible, don’t share towels, pillows or washcloths with anyone else.
  4. Don’t share contact lenses or accessories (solutions, cases etc).
  5. Don’t share eye medicine or eye drops with anyone.
