Insect vision is primarily based on compound eyes, which consist of thousands of tiny lenses called ommatidia. Each ommatidium captures a small part of the visual field, allowing insects to see a wide panorama. This structure enables them to detect movement and changes in light quickly, which is crucial for survival. Insects can perceive ultraviolet light, which is invisible to humans. This ability helps them locate flowers, as many plants have patterns that guide them to nectar. Additionally, some insects, like dragonflies, have exceptional vision, allowing them to track prey and navigate effectively in their environment.
