'Switch-off sunglasses' block out screens

A pair of sunglasses that can block out TV screens has been designed by a company in the US.

The IRL - or In Real Life - glasses use polarised lenses to make television displays appear black.

The BBC's Cody Melissa Godwin asked IRL founder Ivan Cash whether people would be willing to wear sunglasses inside.
