Why Zac Efron wore sunglasses on ‘Today’ show: ‘He’s not well’

He got a little shady.

Zac Efron wore a pair of black sunglasses during an interview on the “Today” show — due to an eye infection.

Efron, alongside co-stars Jeremy Allen White, Harris Dickinson and Stanley Simons, appeared on the morning program to promote their new film, “The Iron Claw.”

“Zac Efron is a legitimate bonafide Hollywood superstar but that is not the reason he is in shades right now,” host Craig Melvin laughed as he introduced the quartet.

The “High School Musical” actor then apologized for his appearance.

“No, I’m sorry man,” Efron, 36, told Melvin, 44. “I feel weird being in shades.”

“I just have a bit of an eye infection,” the “17 again” star explained. “But I really wanted to be here. It’s such a good movie, and I want to come see you guys and tell everyone about it.”

The film — which hits theaters Dec. 22 — tells the true story of the Von Erich brothers, who were memorialized in wrestling history in the 1980s as they attempted to cope with a series of personal tragedies from 1959 to 1993, which are now referred to as the “Von Erich curse.”

Efron’s appearance initially sparked concern by viewers.

“Omg Zac wearing shades inside is not normal,” one fan posted on X (formerly Twitter). “He’s not well. He’s having eye problems for sure.”

“Zac Efron wearing these sunglasses indoors isn’t gonna dispel any of the rumors or worry going on about him,” a second person commented.

The Post reached out to Efron for comment.

This is not the first time the “Greatest Showman” actor’s appearance has caused ripples online.

In June, several online trolls said that the “Neighbors” star looked “unrecognizable” after appearing in a promotional interview for Entertainment Weekly.

One Instagram user slammed the actor by saying that he looks “like a Minecraft character.”

Another commenter trolled Efron by saying he “looks like Lord Farquaad in Shrek.”

The online battle over whether or not the “Hairspray” star had gotten plastic surgery — later dubbed “jaw-gate” by Men’s Health — was so fierce, that Efron was forced to reveal the reason behind his new look.

Last year, Efron told the outlet that he slipped in a pair of socks while running in his house and smacked his chin against the corner of a fountain, knocking him out, in 2013.

After regaining consciousness, Efron could feel his chin bone hanging off of his face.

According to the actor, the masseter muscles — which are used by the mouth for chewing — just continued to swell in order to compensate for the extra work they now have to do.

“The masseters just grew,” he said. “They just got really, really big.”
