With the announcement of its Spectacles 3 sunglasses, Snap must be hoping three times will be the charm. Unlike the two previous generations of the product, Spectacles 3 has two HD cameras to add depth perception to the peepers' repertoire. "The second camera for depth should improve capture and the overall experience, if not add anything truly new," said Eric Abbruzzese, senior analyst at ABI Research. The slick sunglasses have lightweight steel frames, circular lenses and, at $380, are more than twice what previous models cost.
