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

A bed bugs eye is made up of hundreds of eye lenses called facets that fit collectively in a hexagon structure. An easy way to picture what this insects eye looks like is to think of a bee honey comb in a conical shape and not flat. It’s like a soccer ball, but on a smaller, more complex level. The person aspects encompass two lenses, one on the surface and one on the inside. The bed bugs twin lens eye construction permits it to see in 3-D. All of these sides fitted collectively construct the parasites eye. These aspects are linked to tubes that focus light down a central construction called the rhabdome. The rhabdome is light sensitive and directs the data through an optic nerve to the bugs brain.

Every particular person aspect in the bed bugs eye sends a different picture to it’s brain. When all these photos are processed and put collectively a mosaic is created. This 3-D mosaic is how the bed bug can see it’s human host. It isn’t known if, as the bed bug moves, the image it sees updates on a whole or takes micro-seconds for each lens to replace the visual information. If this parasitic insect’s vision updates lens by lens then it would see a continuously updating picture. This view would kind of be like looking by way of a kaleidoscope with three-D glasses on.

Bed bugs come out at night time or in the dark to feed on their human hosts for a few reasons. One reason is because at night, if you find yourself in your bed sleeping, you won’t really feel them crawling on you and biting you. One other reason could possibly be that these blood suckers have light sensitive eyes that enable them to see better in the dark. These compound eyes may also pick up a heat signature of the human body. This is why the keyity of bed bug bites occur on the middle of mass part of your body. Your heat signature is warmer on your torso, legs, and arms than it is on your fingers and toes.

Humans might have color vision that updates consistently where as bed bugs compound eyes see in black and white. Their eyes also don’t consistently replace the full picture without delay, however they can see very well to do the job they’re best at. That job is to discover a human host in which to feed off of their blood.
