The eye infection is caused by Acanthamoeba, which may lead to intense eye pain, Red Eye, and more.

Acanthamoeba is a free-living amoeba found in various environments like soil, dust, air, and water. 

The amoeba can cause infections in humans when it comes into contact with the eyes, skin wounds, or through the respiratory system.
