Short Answer
Cockroaches have two compound eyes which allow them to see objects in a wide range of directions.
They also have three ocelli, which are light-sensitive organs that help them to detect light intensity and direction.
Cockroaches have poor vision and rely more on their antennae to sense their environment.
They are able to detect movement of objects in their field of vision, but are not able to make out fine details.
Anatomy of a Cockroach’s Eye
Cockroaches have compound eyes that are made up of thousands of tiny lenses, allowing them to see more of their environment at once.
This type of vision is known as ommatidia, and it gives them a wide field of view.
The individual lenses of a cockroachs eyes are called facets, and each one captures a single image.
The images are then sent to the cockroachs brain to be combined into a single, larger image.
This allows the cockroach to see in three dimensions, giving it the ability to accurately judge distances and avoid obstacles.
The compound eyes of a cockroach are also incredibly sensitive to light.
While humans and other animals need bright light to see, cockroaches can see in the dark.
This is because they have an extra layer of cells in the eyes called rhabdomeres, which are sensitive to light in the ultraviolet spectrum.
This allows them to detect light that humans cannot see, and gives them the ability to see in low light conditions.
Cockroaches also have excellent peripheral vision.
This means they can detect movement easily, allowing them to spot potential dangers or prey.
Studies have shown that cockroaches can also distinguish between colors, though they are most sensitive to blues and greens.
This helps them to determine the best place to hide from predators or to find food.
Overall, cockroaches have a remarkable visual capability that allows them to navigate their environment and survive.
Their compound eyes enable them to see in the dark and in three dimensions, while their peripheral vision and color perception give them the ability to spot potential dangers and to find food.
This makes them one of the most visually adept species on the planet.
