Dita Condor - Carlos Ponce - Murder Mystery 2
The glasses have aviator shape, but the details of the hinges (see images on the left) show that this is the now discontinued Dita Condor model.
It looks like the silver or white gold model but with custom lenses.
Buy the silver Dita Condor on Amazon.com ($163, best deal).
You can also find the Dita Condor on eBay (note that there is also a newer Condor Two model which is slightly different, so make sure to look for the Condor, for example color code 21005 for the silver model).
This is not the only Dita model in the film: actor Adeel Akhtar wears the Dita Mach-Eight.
Carlos Ponce plays the Helicopter Pilot in Murder Mystery 2. He appears at the beginning and the end of the film, wearing the same sunglasses.
