Summary: Contact lenses for the refractive error correction are one of the most effective methods. Despite relatively low incidence of adverse outcomes, they may be associated with serious morbidity. Contact lens-related Acanthamoeba keratitis was relatively rare but the incidence has progressively increased since then. Such outbreaks may be the result of lapses in contact lens wear hygiene. Acanthamoeba keratitis is a sight-threatening infection of the ocular surface. This disease produces an exquisite pain and ulceration of the ocular surface. The reasons for the increase in microbial keratitis involving species associated with contact lens infections remain unknown. Possible contributing factors include poor lens care hygiene (including elimination of the rubbing step), inadequate lens storage case hygiene or introduction of new contact lens materials, that may promote pathogens adherence. Furthermore, there is an increased demand for cosmetic contact lenses, particularly among teenage girls, what can contribute to the number of infected individuals. The regular follow-up of the contact lenses users and their education associated with lens storage and disinfection techniques are essential. These practices should be endlessly reviewed with patients. It is the only way to prevent different types of keratitis in contact lens users.
