According to eye specialists, the leading cause of corneal ulcer is an infection. Your eyes are exposed to the environment and that is why it can get easily infected, including most especially your cornea which sits on the top of your iris, the colored part of the eye.
Do you wear contact lenses all the time? Then you are at risk of having corneal ulcer. This is most especially true if you do not clean your contact lenses properly. A contaminated contact lens can introduce bacteria to your cornea. Those bacteria can produce toxins capable of causing ulcers on the cornea.
Even if your contact lenses are clean, you may still end up with corneal ulcer if you put on expired ones or wear disposable contact lenses for a very long time.
An eye infection due to the herpes simplex virus may affect the cornea, and it’s also something that can lead to corneal ulcer. Unnecessary sun exposure, stress and anything that can weaken your immune system can cause a flare up, just like a cold sore which is caused by the very same virus.
It’s not just bacteria and viruses that can cause corneal ulcer as a result of an infection, but also fungi. A fungal infection affecting the eye can happen after an injury to the eye involving a plant or any material that has something to do with plants. It’s more common in people whose immune systems are weak.
Eye experts say that other things that could cause corneal ulcer to strike include having dry eyes, an eye injury, being deficient in vitamin A, and having an inflammatory disorder.
