Carrera 5405 - Luke Hemsworth - Ocean Boy
The movie is set in the 1980s so this style of sunglasses is an appropriate choice.
The black and gold aviator Carrera 5405 model is not produced anymore, but you can still find these at some vintage sunglasses stores online or on eBay. Carrera still offers many similar 1980s style frames, find those on Amazon or eBay.
