While we're at it, what about holograms? You get images that look like the real thing from every angle, and there's no lens involved at all in making them! In fact, if you buy a laser pointer to make the picture, you take out the lens first to make it work.

Thanks for the graphic but I think everyone is getting confused here. Light does many neat things and shows up in all kinds of ways that are interesting to observe, but this has nothing to do with an organism needing a lens in order to see, or a camera needing a lens in order to capture a photograph on film.
LENS ELEMENTS & IMAGE QUALITY
All but the simplest cameras contain lenses which are actually comprised of several "lens elements." Each of these elements directs the path of light rays to recreate the image as accurately as possible on the digital sensor. The goal is to minimize aberrations, while still utilizing the fewest and least expensive elements.
Understanding Camera Lenses
Vertebrates have camera type eyes that are capable of forming clear images.
