Walmart is recalling 850,000 stainless steel water bottles because the lid can pop off, causing serious injuries upon impact

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 screw-on lids on the Ozark stainless steel water bottles can forcefully eject, posing "serious impact and laceration."
