As a result, these dragonfly species probably also have a corresponding decrease in overall color perception. The Clubtails are often difficult to find. In contrast to a human eye, each facet within the compound eye points in a slightly different direction and perceives light emanating from only one particular direction in space, creating a mosaic of partially overlapping images. Dragonflies can also detect the plane of polarization of light, which humans cannot do without the aid of sunglasses. Another visual advantage of the multifaceted eye is a dragonfly's acute sensitivity to movement, as anyone who has tried to catch one can tell you.
Dragonflies can see in all directions at the same time.
The spherical field of vision means that dragonflies are still watching you after they have flown by. However, the backward-looking part of the eye has rather low resolution. So, if you want to catch a dragonfly, let it go by you and then swing your net like a baseball bat from behind. If you swing at them while they are approaching they'll usually see the net coming and easily avoid it. They are awfully good at what they do.
