If there’s one thing you see everywhere in Montana, it’s people lugging around their trusty metal water bottles. Maybe it’s a trend, maybe it’s our dry air and high elevation, but staying hydrated seems to be a full-time job out here.

But here’s something I didn’t expect: one of the biggest retailers in the country, Walmart, is issuing a major recall on a popular brand of metal water bottles after some seriously scary injuries.

Now, if you’re like me, your first reaction is probably, “How do you even get hurt by a water bottle?” Is it toxic? Cracking open? Spontaneously combusting? Well, not quite—but close enough. This specific model has already blinded two people after the lid forcefully ejected off.

Two People Have Been Blinded By Recalled Water Bottles

Yes, you read that right—launched. Into their faces. If you’ve grabbed one from Walmart recently, especially one of their big Ozark Trail models, you might want to take a second look.

According to the U.S. Consumer Product Safety Commission, the lids on some 64-ounce Ozark Trail stainless steel bottles can launch off with force, especially if you’ve stored anything other than water in them—like juice, soda, or milk.

Three people have already been hit in the face when opening them, and two have reportedly suffered permanent vision loss. The bottles in question are silver with a black screw-on lid and have no model number printed on them, but if the packaging said model 83-662 and it’s about 11.5 inches tall with the Ozark Trail logo—you’ve got the one.

So if you’re one of the many proudly hydrated folks walking around with a metal bottle in tow, it might be worth double-checking which one you’ve got. Because staying hydrated shouldn’t come with a risk of losing an eye.
