Underwater vision
Light rays bend when they enter from one medium to another of different densities making it possible to form images on the retina of our eyes by focussing the rays on the retina. If both the media have almost the same refractive indices (which determines the extent of bending), light rays would not 'bend properly' to be focussed on the retina of our eyes.
