The CPSC and Walmart have issued a voluntary recall notice for consumers to get a full refund and stop using or return the Ozark Trail water bottle immediately.

The lids on the 64-ounce stainless steel bottles can eject and strike consumers, two of whom reported permanent vision loss as a result, safety regulators said.

The retail giant is offering a full refund for the bottles. The U.S. Consumer Product Safety Commission warns of impact and laceration hazards.
