4. Acanthamoeba is a frequent cause of eye ulcers.
Acanthamoeba is a parasite that is found in swimming pools, tap water, hot tubs, and any other sources of water. The parasite is common in people who wear contacts. The parasite can cause vision loss and permanent scarring in the cornea. When swimming in pools, hot tubs, or any other water sources, it’s best to take out your contact lens.
Contact lens wearers may feel like they won’t be able to see when they wear them in the water. Unless you are completely blind, you will still be able to see. Even if you wear goggles, eye ulcers can still occur. It is even worse at a community swimming pool because there are lots of other people who use the pool.
If they already have an eye ulcer, they could possibly pass it on to others. An eye ulcer is caused by fungi and fungi can spread from person to person.
