how many eyes flies have

Flies are insects that belong to the order Diptera. They have two eyes, which are typically large and widely spaced. The eyes of a fly are composed of thousands of tiny lenses called ommatidia, which are arranged in a hexagonal pattern.

Each ommatidium is responsible for detecting light and dark, and the combination of all the ommatidia in the eye allows the fly to see a wide field of view and detect movement. Flies have excellent vision and are able to see in all directions, including up, down, and behind them.

Flies use their eyes to navigate and locate food, mates, and other resources. They are also able to see ultraviolet light, which helps them to locate flowers and other nectar sources.

In addition to their eyes, flies have other sensory structures that help them to navigate and interact with their environment. These include antennae, which are used to detect smells and vibrations, and taste sensors, which are used to locate and evaluate food. Flies are also equipped with wings, which allow them to fly and move quickly from place to place.
