"It would streamline the design and function of these systems while also offering a way to accomplish imaging at various depths without additional optical elements. These capabilities, coupled with the lens's multifocal properties, offer a powerful tool for depth perception in advanced imaging applications"

The eagle had lost its depth perception, meaning that in going for a kill of a rabbit, it would miss.
