Someone get this Mafia prince a pair of glasses.

The namesake grandson of notorious Colombo crime family boss Carmine “The Snake” Persico — who recently underwent eye surgery — started a gang attack when he mistook a complete stranger for someone he knew, law enforcement sources told The Post.

The young and optically challenged Persico, 25, punched the victim in the face outside a Brooklyn bar, ironically telling him, “You look familiar,” sources said.

Three Persico pals joined in the early Thanksgiving beating, which left the victim with a broken jaw and a stab wound to the abdomen, according to court papers.

While fleeing, Persico dropped his keys, which were scooped up by a Good Samaritan who had tried in vain to stop the attack outside the Kettle Black bar in Bay Ridge, sources said.

Cops used an electronic key to unlock a black 2015 Chrysler 200 parked nearby, then traced the car to the mob scion.

He was charged with a slew of crimes, including first-degree assault and second-degree gang assault. Three alleged accomplices remain at large.

Persico was freed on $5,000 bond following an arraignment at which his Legal Aid lawyer said he was planning to join the US Navy once he fully recovered from laser surgery to improve his vision, sources said.

Persico’s namesake grandfather is serving 100 years in the slammer for his 1986 conviction in the landmark Mafia “Commission” case.

Here’s how you get a mafia nickname:

Uncle Alphonse “Allie Boy” Persico is serving a life sentence for ordering the murder of a mob rival, while another uncle, Michael, is awaiting sentencing for loansharking.

Hid dad, middle son Lawrence, did time for a no-show union job, but was recently spotted delivering pizzas in Brooklyn.

Victim Charles Pickering — who spent three days in the hospital — said he only learned of Persico’s infamous pedigree from a grand jury notice and the internet.

“I never met him before in my life,” said Pickering, 22, who spoke through a wired jaw. He said he was outside the bar with pals when Persico approached and borrowed his lighter.

“I got my lighter back already and he was like, ‘Oh, you look familiar,’ so I turn around and all of a sudden he just hits me,” Pickering said.

Despite Persisco’s notorious pedigree, Pickering said he wasn’t afraid of further violence, repeatedly noting: “It’s the 21st century.”
