An Indian factory stands accused of being the source of contaminated eye drops that have consumers on edge.

The US Food and Drug Administration recently released an alert, claiming that more than two dozen over the counter eye drop products posed potential risk to consumers.

The FDA pointed to 26 products being sold at major retailers including Target, Rite Aid and CVS, warning that it was possible these products were not, in fact, sterile. They say that applying these remedies via the eye means they can “bypass some of the body’s natural defenses.” In this case, potential bacterial contamination, the FDA says, could lead to blindness in users.
