Contact Lens User

Acanthamoeba Keratitis is increasing amongst contact lens users.

Contact lenses are medical devices so extra care is necessary to ensure you can enjoy your contact lenses and have happy, healthy eyes. 

AK is caused by a free-living amoeba (parasite) that is typically found in soil, bodies of water and tap water; so, showering, bathing, swimming in pools, lakes, ponds, oceans, bathtubs, and even rinsing contact lenses or cases with tap water can put you at risk

Educate yourself – it is your right – on what you can and cannot do with your contact lenses from your trusted eye doctor. 

Always have your routine eye exams and use official products.


Symptoms vary, so as we always recommend, if you are a contact lens user and have been in contact with water and your eye is feeling “different”, then:

  • take your contact lenses out!
  • get your eye checked by an eye professional as soon as possible!
  • don’t forget to tell them that you are a contact lens user and have been in contact with water.

If available, advocate for an early confocal scan! Time is of essence.
