Martian Eyes Are Watching

This image shows a closeup view of the two pairs of camera lenses on a shelf. The left-hand pair are larger than the right-hand pair, go to the hazard avoidance camera, and have a larger, fish-eye lens field of view for examining the rover's wheels and immediate surroundings. Its lenses are a clear, almost-turquoise blue. The right-hand pair of lenses are smaller and go to the navigation camera, which takes panoramic, far-field images of surrounding terrain.
