Humans 'can see polarised light'

POLARISED light can be 'seen' by humans, as well as bees and insects - although it is a skill which has been lost.

IT may not quite be X-ray vision but it is the kind of ability that brings to mind superheroes or gifted mutants.

HUMANS have eyes that can sense a third property of light besides colour and brightness. And despite being better at it than any other vertebrate tested to date, most people have no idea they possess the skill.
