Atlanta ? Government officials are warning people to throw away a contact lens solution after an investigation linked it to a rare eye infection.

The warning concerns AMO Complete Moisture Plus Multi-Purpose Solution, used for cleaning and storing soft contact lenses, said a spokeswoman for the U.S. Centers for Disease Control and Prevention.

The solution seems to be a factor in cases of Acanthamoeba keratitis, a painful eye infection that can lead to permanent vision loss or blindness.

The CDC and the U.S. Food and Drug Administration are investigating 138 confirmed cases.

The solution is made by Advanced Medical Optics Inc., a publicly traded company based in Santa Ana, Calif.

CDC officials said people should discard the solution, throw out their current contact lenses and toss the lens storage case. All of them may harbor the infecting amoeba, said Michael Beach, team leader in the CDC’s division of parasitic diseases.
