"Eyeballing," a drinking game where participants pour vodka directly into someone's eye, is the latest -- and dangerous -- fad, and videos of the act are even popping up online.
"They're not doing this eyeballing to get drunk, they're doing it after they're drunk and they're drunk enough to act stupid," Mike Gimbel, a substance abuse expert told Fox41. "They're actually doing it as part of a fad. You know, I dare you to do this."
Hundreds of YouTube videos have been put up to document the practice.
"Vodka is about 40 to 50 percent pure alcohol, which can take off the top layer of the cornea," Robert Stutman, president of the Maryland Optometric Association told Fox41. "It can cause scarring. Can it make you go blind? I suppose it probably could, if it causes severe enough scarring of the cornea."
Dr. Barry Eiden told AOL Health that once the damage to these surface cells of the eye occurs, there is a possibility that with prolonged exposure damage to deeper layers of the cornea may lead to permanent vision loss.
He added that because these teens are intoxicated while "eyeballing" it's likely that their pain tolerance will be heightened and sense of urgency depleted, so they would not try to immediately flush their eye out with water.
