If you accidentally shower or swim while wearing soft or RGP contact lenses, you face a heightened risk of exposing your eyes to waterborne microorganisms like Acanthamoeba, which can cause severe, vision-threatening corneal infections. You should immediately remove your contact lenses upon exiting the shower, clean and disinfect them thoroughly if they are reusable, or discard them if they are dailies. Monitor your eyes closely for redness, pain, or blurred vision, and consult an eye doctor immediately if symptoms arise.
