Why are Fresnel lenses useful for navigation in water?
This may or may not answer your actual question; the wording is a little ambiguous. Fresnel originally developed the lens style named after him for use in lighthouses. The lenses used in lighthouses needed to be very large and have a short focal length, but short focal length lenses need to be highly curved. That combination means that in a plano-convex lens, the middle is much thicker than the edges, and not only does the lens require a lot of (expensive) glass, it's heavy and has thin fragile edges. The lens Fresnel designed overcame these problems, and so made it possible to for lighthouses to have extremely large and powerful lenses that previously would have been impractical.
