Why do some animals have specialised eyes?

Specialised eyes help animals adapt to their specific environments and lifestyles. For example, birds of prey like eagles have sharp vision for spotting distant prey, while nocturnal animals like owls have large eyes to maximise light intake in low-light conditions. Animals like chameleons can move their eyes independently, giving them a wide field of view to spot predators or prey. Marine animals like octopuses have highly developed eyes to see clearly in dim underwater environments. These adaptations enhance survival by improving perception.
