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.

Walmart is recalling about 850,000 stainless steel water bottles because the lid can “forcefully eject” and unexpectedly strike consumers — resulting in permanent vision loss for two people to date.

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.
