Why do some animals have sharp vision?

Sharp vision in animals is an adaptation that helps them detect predators, find food, or navigate their environments. Birds of prey, such as eagles and hawks, have incredibly sharp vision, allowing them to spot small animals from great heights. Their eyes have a high density of light-sensitive cells, enabling them to see fine details even from a long distance. Some prey animals, like deer, have a wider field of vision to detect predators from multiple angles, enhancing their chances of survival.
