True Vintage Revival TVR502 Diamond Shape - Zac Efron - Dirty Grandpa

Zac Efron wears a pair of True Vintage Revival TVR502 Diamond Shape vintage-style tortoise sunglasses in Dirty Grandpa.

The glasses feature a tortoise shell frame, brown lenses and diamond shape rivets on the fronts and temples.

This 1960's style eyeglasses with keyhole nose bridge and diamond rivets on front and temples are from True Vintage Revival TVR OPT, a Japanese glasses manufacturer. Every frame is made entirely by hand by craftsmen in Sabae, Japan using the same tools and techniques passed down across 100 years.

In the same film, Robert DeNiro wears Loree Rodkin Ashton by Sama sunglasses.
