With improvements in facial-recognition technology and the increasing popularity of smartphones, the threat to one's privacy unexpectedly posed by random Internet photos posted by strangers is growing day by day.

The Privacy Visor consists of a titanium glasses frame with a mesh-like screen one can see through.
