I love sunglasses. Everyone looks cool in the right pair. With the advent of Face ID on iPhone X, while wearing sunglasses, sometimes Face ID can not "scan" through them—many sunglasses work with Face ID while others don't.
While reviewing sunglasses for Adrian's Gear, I've been collating a database of sunglasses that I have confirmed to work with the current generation Face ID for iPhone X.
This list is always growing and is current as of sunglasses available May, 2018.
For more, search for 'Sunglasses' and 'Face ID' or your brand of interest in Hexagon.
