Yes, ants do have eyes, but their eyes have a different structure and function than humans.
Compound eyes (compound eyes): An ant's eye is usually made up of compound eyes. A compound eye is an eye structure made up of many small light-sensitive units. Each small unit is called an "ommatidia" (ommatidium in the singular) and they are the basic building blocks of the compound eye. Each ommatidium has its own lens and retina that is able to sense light in its surroundings.
Monocular Eyes: In addition to compound eyes, ants may also have one or more pairs of monoculars. These monoculars are located at the top of the ant's head and help to perceive the light and the direction of the light.
Perceiving movement and light direction: While ants' compound eyes do not provide clear vision similar to that of human eyes, they can perceive light, light direction, and movement. This visual structure helps ants perceive food, danger, and other ant activities in the environment.
Multi-domain vision: Each ommatidium can perceive a view of a small area, and the combination of multiple ommatidium is capable of providing a broad visual perception of the surrounding environment, but does not have high definition or color vision.
Adaptation to low-light environments: Ants' compound eyes are sensitive to changes in light, allowing them to perceive faint light even in dark environments.
In addition to vision, ants rely on antennae and chemical perception to detect their surroundings. Antennae help them perceive chemical information about the terrain and environment, such as chemical signals released by food and companions.
In general, although ants have eyes, their vision is not as high-definition or colored as humans. Their compound eye and monocular structure allow them to perceive light and movement, helping them find food in their environment, avoid danger, and sense the presence of other creatures.
