Cockroaches are known to show signs of peculiar behavior. Among the traits that stand out, their quick reflexes take the lead. As soon as there’s any noise, activity, or light around them, they instantly run out of fear.
This raises the question: Do roaches have eyes? How Many do they have?
Here’s what we know:
- Cockroaches have eyes with complex features
- Their eyeballs are located at the top of their heads
- Cockroach’s eyes have 2000 lenses
The more you learn about cockroaches and their anatomy, the more complexities you’ll find. Their eyes are no exception to this phenomenon.
These creatures can enjoy 360-degree vision, which keeps them on their toes.
Do Roaches Have Eyes? How Many Do They Have?
Although they look nothing like ours, cockroaches do possess eyes. In some ways, cockroaches are very simple. But in other ways, they are quite complex. Their eyes definitely lean toward the complex! A roach’s eyes provide a 360-degree vision of their surroundings.
Cockroaches enjoy numerous remarkable features through their eyes. However, there are also some limitations.
These pesky little creatures have eyeballs on their heads and enjoy over 2000 lenses. This enables them to see numerous things simultaneously rather than one thing at a time. Their placement is such that they are located on the top of the cockroach’s head at their body’s front.

Cockroach bodies are normally flattened, round on top, and surrounded by a thick exoskeleton.
Since their eyes are located at the top of their head as opposed to the front, cockroaches can enjoy the ideal view of their surroundings like humans.
These pesky creatures have more than one lens, which makes their eyes compound.
How Many Eyes Does a Cockroach Have?
It is no mystery that cockroaches are widely different from other insects due to their strange traits and intelligence. This also translates into their eyes, which are complex with numerous lenses.
Although small in size, their eyes consist of more than 2000 lenses. This allows them to have a view of the back and the front at the same time.
However, sight capabilities also vary from specie to specie. Madagascar roaches carry a greater number of lenses than other cockroaches i.e. between 2500-3000 lenses. Therefore, this specie of cockroach has a superior 360-degree movement to other species.
Can cockroaches see when it’s dark?
We know that cockroaches are nocturnal insects that come out at night. These creatures hide away in warm and dark spots during the daylight and emerge to hunt for food as the sun sets.
One pressing question arises when relating this idea to their sight: can cockroaches see when it’s dark?
The answer is yes.
Cockroaches can see during both times of the day through their complex and advanced eyes.
However, since their vision isn’t as clear as that of humans, they prefer to hide away to increase their chances of survival.
Do cockroaches have eyesight limitations?
Despite these creatures’ advanced eyesight, they are victims of some limitations. For example, their lenses get distorted shapes towards the outer ends of their eyes.
Their lens asymmetry can also impact their vision in the middle of their eye. However, this is fairly rare, and since they have so many lenses, the asymmetry is normally not a big deal.
Another limitation of these cockroaches is that they lose their ability to see in the red light. However, they are well-equipped to see in the green light.
It is also important to remember that even though the eyes are integral body parts, cockroaches can survive without their heads for quite some time!

Are cockroaches’ eyes compound eyes?
Cockroach’s eyes are divided into two types: compound and simple. Their forehead carries three simple eyes, including two large, black, sessile, and kidney-shaped structures on the dorsolateral sides of the head and one eye called the ocelli.
These eyes are, indeed, compound eyes and are made from ommatidia.
Can cockroaches see humans?
Cockroach’s advanced 360-degree vision allows them to see everything, including humans.
Due to their ability to perceive us, they can flee in fear as soon as we come near them. You may have noticed that regardless of the angle you approach a cockroach from, you can’t hide from them.
This is precisely due to their 360-degree vision and compound lens, consisting of more than 2000 lenses called photoreceptors.
These also aid them in being able to see clearly in complete darkness.
How does a cockroach see the world?
In some ways, cockroaches can enjoy traits that humans do not possess. Most organisms and humans fail to process light signals at a high rate. Cockroaches gather the photon signals they notice over time, making a long exposure reflection of the specific scene that allows them to see.
Are cockroaches blind?
Despite immensely small bodies, cockroaches have far superior senses that allow them to monitor predators, find food, and survive in a harsh world that crawls with human and animal predators. These insects are well-equipped to take note of danger, and their eyes play a major role in doing so.
However, while their sense of sight is immensely strong, they lack ears.
While their sense of sight is immensely strong, they lack ears.
Therefore, instead of hearing, they opt for various alternative methods to communicate with the world. Luckily, their exceptional sense of sight and ability to sense danger makes up for the potential limitation of lack of hearing.
Conclusion: roaches have eyes, three of them!
Cockroaches have eyes, three of ’em! Their eyes are far superior to most living organisms, including humans, with thousands of lenses and a 360′ field of vision.
It is important to remember this fact when we attempt to underestimate their capabilities due to their small-sized, easily-crushable bodies.
Therefore, if you’re trying to creep behind a cockroach in an attempt to kill it, know that it is probably 10 steps ahead of you and will make a run for it before you even angle yourself appropriately in his direction.
These insects are fast, alert, and far-sighted. This allows them to detect danger from far away and protect themselves through an array of defense mechanisms. Sometimes, these cockroaches will run towards you to startle you and then run away. Other times, they will play dead.
The bottom line is that these creatures will do anything to protect themselves and their eyes help immensely.
