They can, indeed. Cockroaches are able to perceive humans, which is why they flee in fright when we come into their field of sight. The cockroach’s eye is similar to a compound lens; it is composed of over 2,000 tiny lenses called photoreceptors that enable it to see in full darkness.

Are Cockroaches Blind?

Roach Vision

Cockroaches have extremely flat bodies that are rounded on top and covered in thick armor. The eyes are located near the top of the rounded head at the front of the body, rather than on the front, as in humans, or on the side, as in many other mammals, giving cockroaches a near-perfect view of what is going on around them.

Additionally, their eyes are compound, which means they have several lenses.

Limitless Lenses

In comparison to human eyes, which have a single lens, cockroach eyes have around 2,000 lenses. For example, Madagascar hissing cockroaches have between 2,400 and 2,500 hexagonal lenses in each eye.

Males have additional receptors on their antennae to assist them in sensing female pheromones when females are ready to mate.
