But, bees can. They see these shiny petals and associate them with sugar. Thus, the flower becomes more attractive to the bee and gets pollinated. The car is moving so fast that the flowers blend in to one another and we see a blur of color.
They can see individual flowers while traveling at a high rate of speed. Because of this, they actually respond better to moving objects than stationary ones. Flying helps bees see better. They can see depth and they can see three dimensionally.
They can also judge distance. They communicate these distances and directions of good foraging sites to the hive through their waggle dance. However, scientists have found that it is possible to trick bees into misjudging distances. In one study, a tunnel was painted in a semi-checkered pattern. When the bees passed through it, they became confused regarding the distance of the tunnel. The checkered pattern caused them to think the tunnel was longer, because they thought they were passing by a lot of objects.
When the scientists painted horizontal stripes in the tunnel, the bees flew too short. Thus, scientists realized that bees use the objects they fly by to judge distances, which they later communicate to the hive.
Bees have two different types of eyes-each with separate functions. These little bee eyes have single lenses and help the bee maintain stability and navigate. They enable the bee to judge light intensity and stay oriented. Using these ocelli, bees can gather light and see ultra-violet light, helping them to detect UV flower colors. If a bee were a superhero, its sight would be its super power.
Every bee has two large compound eyes. A compound eye is made up of thousands of tiny lenses called facets. Worker bees have 6, facets in each eye, and drones have 8, facets. Every facet is connected to a tiny tube.
Each of these units, called an ommatidium, contains a lens facet , a cone of visual cells and pigment cells that help separate it from its neighbor cells. A bee is able to see color, because each of these tiny tubes contains eight cells that respond to light.
Four of these cells respond to yellow-green light, two respond to blue light, and one responds to ultraviolet light. A bee can also detect polarized light. Polarized light moves in one direction.
They are able to use this polarized light as a navigating system. They then communicate these directions to the colony. Bees can find their way back home by checking the pattern of polarized light in the sky. Due to its intense brightness, looking at the sun directly is a very difficult and dangerous thing to do. Light from the sun can permanently damage the eyes.
Students may be aware of the damage the can be caused by the sun during a solar eclipse. In preparation for the eclipse, people are told to not look directly at the sun during an eclipse.
That is because powerful ultraviolet radiation can severely burn and damage the eyes even though this form of light cannot be seen. How do you think the telescope changed the study of astronomy and, specifically, sunspots forever? Telescopes not only protect the eye from direct contact with the sun, they also allow scientists to observe the sun and other solar bodies that are far away.
With the invention of the telescope, observers were able to confirm the existence of sunspots on the sun and use the instrument to make detailed observations about their size, shape, and movement across the sun. Tell students that older telescopes, like our eyes, allow us to see in the visible light, or white light range. What is visible light?
Students should know that visible light refers to the wavelengths of light that are visible to the human eye. If white light were exposed to a prism, what colors would emerge? Red, orange, yellow, green, blue, indigo, and violet. What kind of electromagnetic radiation has the shortest wavelength? The longest? Gamma rays have the shortest wavelength. Radio waves have the longest. What kind of electromagnetic radiation could be used to "see" molecules?
A cold virus? X rays allow us to "see" molecules. Ultraviolet waves can be used to "see" a cold virus. Some insects, like bees, can see light of shorter wavelengths than humans can see. Ocellar structure and neural innervation in the honeybee. Frontiers in Neuroanatomy , 8 , 6.

Note that in the UV range, the flower has clear dark markings around the centre that are not visible to us.
These markings are thought to act as a guide for pollinators [2]. Navigation Using Light Another quality of light that bees pay attention to that we hardly notice is polarization. But How Do We Know? The Eyes Have It The last topic I want to touch on with respect to vision is probably the most obvious: honey bees do not have the same type of eyes as humans.

Broccard-Bell Beauty is in the Eye of the Beholder Like us, honey bees rely quite a lot on vision to navigate through their world—but as we have seen, the way they do this is rather different from humans. Good news: they do and yes, they are just as interesting!
