Why eagle can see better than human?

Eagles have superior vision compared to humans due to their larger eyes, which contain a higher density of photoreceptor cells, particularly cones that detect color and detail. Their eyes are also adapted for long-distance viewing, allowing them to spot prey from great heights, with a field of view that is nearly twice that of a human. Additionally, eagles have a special structure called the fovea, which provides them with exceptional visual acuity. These adaptations enable them to see a broader spectrum of colors and finer details, making them highly effective hunters.
