Of course the only problem with what you've written is that it's rubbish...
The parasite is commonly found in soil, dust, showers, and even swimming pools. When it makes contact with unclean lenses, it starts feeding on the bacteria on them, and if they happen to be on someone's eyes, the parasite burrows down to where it can start feeding on the cornea
So you don't need to do anything except have your eye's open and have dirty lenses (which you don't change) get your cornea eaten, did you read the story at all?
