The bronze sculpture of the Beatles legend, entitled the John Lennon Peace Statue, is located in Penny Lane.
Artist Laura Lian, who created the piece, said it was unclear how one lenses of Lennon’s glasses had broken off but it was thought to be vandalism.
The statue, which has toured across the UK and and Holland, will now be removed for repairs.
Ms Lian later confirmed the second lens had been broken off the statue.
“We found the [first] lens on the floor nearby so I hope it was just the recent frosty weather which was to blame,” she said.
“I see it as a sign that it is time to move on again.”
The statue, which was funded by Ms Lian, was first unveiled in Glastonbury in 2018 and has since been displayed in London, Amsterdam and Liverpool.
