Abstract
A pair of electric goggles is disclosed. The goggles include a conductive lens mounted onto a frame adapted to be electrically connected to an electric socket in order to raise the temperature of the lens, when powered. The goggles are provided with a strap for attaching to a helmet, the strap has a strap clip designed to have the electric socket attached thereto. The electric socket is meant to be electrically connected to a power supply via a power cable. With the combination of a strain relief clip located below the electric socket, the power cable can be positioned in a predetermined configuration, which unencumbers the user from the power cable when detaching or removing the goggles.
