There is a single-celled amoeba that can wreak havoc on your eyes and even lead to blindness, and it is called Acanthamoeba. According to the Centers for Disease Control and Prevention (CDC), this type of amoeba can be found just about anywhere, including in all types of water, in the soil, and even in the air. If this organism makes its way to the eye causing Acanthamoeba keratitis, it can lead to visual impairment that can range all the way up to vision loss. While individuals who wear contact lenses appear to be more at risk for contracting this amoeba, anyone who comes into contact with this organism is certainly at risk. Knowing the symptoms of Acanthamoeba keratitis may help save your vision.
When your eyes are sensitive to the light, it is known as photophobia. The name can be misleading, as this is not a fear of the light, but rather an extreme sensitivity. The irritation caused by the amoeba can increase your eyes' ability to effectively filter light through the corneas or the widening and narrowing of the pupils. While some individuals may feel light sensitivity is a condition in and of itself, it is typically a symptom of some other type of problem with the eyes, including Acanthamoeba keratitis infection. When you are in bright light situations, you may automatically squint your eyes or experience additional symptoms.
