Walmart is voluntarily recalling hundreds of thousands of Ozark brand reusable water bottles over potential injury hazard, the Consumer Product Safety Commission announced this week.

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.

So far, three people have been injured by the lids with two of those people suffering “permanent vision loss” after being struck in the eye, according to the Consumer Product Safety Commission.
