How do fish see through water?

Do fish see oxygen?
Air has an extremely low refraction index, making it impossible to see. Neither us nor fish can see the air in the environment.
Can humans see water?
But about 70 percent of visual refraction occurs as light passes from the air outside the eye into the more dense, fluid-filled eyeball itself. Swimming presents a problem for human vision because water is virtually the same density as the fluid inside the eye, so underwater light barely bends as it enters the eye.
Can you ever see air?

What if atoms touch each other?
In this approach, atoms touch whenever they are close enough to potentially form a chemical bond. 3. If “touching” is taken to mean that two atoms reside in the exact same location, then two atoms never touch at room temperature because of the Pauli exclusion principle.
