How do multiple eyes help Flies see well?

How many eyes does a fly have?

There are two compound eyes on the head of a fly, one on each side. These are very large and overwhelming, making up nearly the entire front of the fly’s face! It’s easy to miss these tiny pores if you’re not looking for them. They are smaller in some species because they have more than one eye on their head.

How do multiple eyes help Flies see well?

  • Multiple eyes give fly a wider field of view, which is useful for spotting predators or prey.
  • Each eye sees a slightly different image, which the brain can then combine into a single, more detailed image.
  • Having multiple eyes can also help fly’s judge distances more accurately.

What is the Purpose of Eyes on Flies?

The purpose of flies’ eyes is very different from the purpose of our eyes

  • For the fly, their eyes are solely responsible for providing a 360-degree vision around them. Focusing images isn’t an issue since they do not use their eyes to focus images.
  • While our eyes focus images by narrowing down the view through the pupil, flies’ eyes are actually wide open and have no pupil to narrow their field of vision down.
  • What they lack in focusing ability, they more than make up for with a very large field of vision that allows them to see in almost every direction at once. This gives them an enormous advantage when it comes to evading predators while they search for food or are laying eggs.

What are the different parts of the fly’s eye?

  • There are three main parts to a fly’s eye: the compound eye, the ocelli, and the optic lobes.
  • The compound eye is made up of thousands of tiny light-sensitive units called ommatidia.
  • The ocelli are simple eyes that can detect changes in light intensity and help the fly orient itself.
  • The optic lobes are the part of the brain that processes the information gathered by the eyes.
