Eye Allergy vs Eye Infection: How to Tell the Difference
Introduction: Eye Allergy vs Eye Infection
Many people wonder about the difference between eye allergy and eye infection. Both can cause red, itchy, or watery eyes. However, knowing the difference matters because treatment is not the same. An eye allergy happens when your eyes react to things like pollen or dust. On the other hand, an eye infection is caused by germs such as bacteria or viruses. Understanding eye allergy vs eye infection helps you get the right care and avoid problems. If you notice eye redness, it is important to know what is causing it.

Although both conditions can look similar, their symptoms often differ. Here is how you can tell them apart:
Common Symptoms of Eye Allergy

Common Symptoms of Eye Infection

As you can see, eye allergies usually cause itching and watery eyes. In contrast, eye infections often cause pain and thick discharge. If you notice these differences, you can better understand what is happening.
