Shiva Shabani wears Garrett Leight California Optical sunglasses. I'm guessing at the specific model, but I think it's Rialto LNA in demi-blonde.
Garrett Leight is son of Larry Leight, he who co-founded Oliver Peoples. Look out for another post on GLCO soon - it's a great collection!
Massive respect to R3SP3CT for the photo of Shiva.
