Time Goggles

Time Goggles, or TiGs, are a type of Plumber-issue set of goggles first seen being used by Max Tennyson in Ben 10: Alien Universe. They are a light grayish color and allow people to view a certain distance in the past similarly to how Clockwork does, but only by the person wearing the goggles. It was developed by the Galvan.

Trivia

 * According to Stripes, the TiGs were made by the Plumbers to give them access to the power Clockwork's species beholds to look at the past.
