How Can Flies See in the Dark?

If we were to ask a fly about its eyesight, it would probably tell us that flies have poorer vision than humans, and their eyes have a lower resolution. In addition, flies have small heads and do not have the same number of facets as humans, which means their vision is blurry. Their bodies also have limited amounts of photoreceptors, which makes it difficult for them to process light quickly and process it in a sharper manner. This means that they can only discern objects within a small distance.

Flies can see colors in the dark, but they are not color-blind. Humans have cones and rods, which each detect different colors, but flies only have two types of these receptors. This makes it hard for flies to differentiate between the different colors. Also, insects cannot see red light, which is the lowest color frequency that humans can see. Despite these limitations, flies are able to see in polarized light. In contrast, humans cannot differentiate between polarized and unpolarized light.

Fly vision is best described as a mosaic. Each ommatidium contains thousands of tiny pictures, which represent individual flies. When seen at a distance, these images combine to form an overall image. However, the compound eye has more ommatidia, resulting in a sharper image.
