Although bed bugs love feeding on human blood they do not have eyes that see like human beings. These parasitic creatures have what’s called a compound eye structure. It is thought that they don’t see in coloration, that they visualize in black and white.

A bed bugs eye is made up of hundreds of eye lenses called facets that fit together in a hexagon structure. A straightforward way to image what this bugs eye looks like is to think of a bee honey comb in a conical shape and not flat. It is like a soccer ball, but on a smaller, more complicated level. The individual sides encompass lenses, one on the surface and one on the inside. The bed bugs twin lens eye structure allows it to see in three-D. All of these sides fitted collectively assemble the parasites eye. These sides are connected to tubes that focus light down a central construction called the rhabdome. The rhabdome is light sensitive and directs the data via an optic nerve to the bugs brain.

Each particular person side within the bed bugs eye sends a unique picture to it’s brain. When all these photos are processed and put together a mosaic is created. This three-D mosaic is how the bed bug can see it’s human host. It is not known if, as the bed bug moves, the image it sees updates on a complete or takes micro-seconds for every lens to update the visual information. If this parasitic insect’s vision updates lens by lens then it would see a consistently updating picture. This view would kind of be like looking by a kaleidoscope with 3-D glasses on.

Bed bugs come out at evening or in the dark to feed on their human hosts for a few reasons. One reason is because at evening, when you’re in your bed sleeping, you won’t feel them crawling on you and biting you. Another reason might be that these blood suckers have light sensitive eyes that enable them to see higher in the dark. These compound eyes can also pick up a heat signature of the human body. This is why the keyity of bed bug bites occur on the center of mass part of your body. Your heat signature is warmer in your torso, legs, and arms than it is on your fingers and toes.

People could have colour vision that updates continually where as bed bugs compound eyes see in black and white. Their eyes also do not consistently update the complete picture without delay, but they can see very well to do the job they are finest at. That job is to find a human host in which to feed off of their blood.
