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 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 on Thursday recalled Ozark Trail 64 oz Stainless Steel Insulated Water Bottles. The water bottle's lid could "forcefully eject" when a person tries to open the bottle after carbonated beverages, perishable beverages or food were stored inside over time, according to the U.S. Consumer Product Safety Commission.
