Rinsing with distilled water was perceived with less risk of infection than rinsing with tap water for SCL wearers (p<0.0001) and GP wearers (p<0.0001).

Storing lenses in distilled water was perceived with less risk of infection than storing lenses in tap water for SCL wearers (p<0.0001) and GP wearers (p<0.0001).
