After a decade of showering with contact lenses, one wearer’s eye turned red and weeping. An ophthalmologist’s discovery revealed a dangerous single-celled organism thriving in tap water—and why 85% of lens wearers are unknowingly at risk.
Millions of contact lens wearers swim without removing their lenses, assuming chlorine makes it safe. What they don’t know is that soft lenses act as a sponge for dangerous single-celled organisms that can burrow into your cornea, potentially causing permanent vision loss. One afternoon in the pool could trigger a year-long infection.
A tiny, resilient organism called Acanthamoeba lurks in nearly every water source, but it becomes dangerous only when a contact lens creates the perfect conditions for infection. Most contact lens wearers unknowingly expose themselves to this risk daily—and doctors frequently misdiagnose the resulting infections, sometimes for over a month.
