What animals can't see well in the dark?

Many animals have varying degrees of night vision, but some species, such as primates, including humans, don't see well in the dark. Certain herbivores, like cows and sheep, also have limited night vision compared to predators. Additionally, some birds, particularly those that are diurnal, rely on daylight for their activities and may struggle to see in low-light conditions. These animals typically have adaptations that favor daytime vision rather than nocturnal sight.
