Why will goggles allow a swimmer underwater to focus more clearly on what he is looking at?

Goggles help you see better underwater due to the change in the speed of light and the Brownian motion of the water. First, light slows down in water. Underwater, with the water pressing against your eyeball, the index of refraction changes and makes the lens in your eye out of focus. Browning motion causes a large number of molecules to pound away at your lens and keep it out of focus.
When you put on your goggles, then your eyes work like they do in air. Light is going at the speed of light. Water is not pounding against your lens getting it out of focus.

What is the difference between nekton and benthos?
Nekton can fight against currents- plankton cannot. Think about the difference between someone who is good at swimming and someone who is not swimming in the ocean. The good swimmer can get pounded by the waves, and still swim in whatever direction they want. But if a bad swimmer gets pounded by the waves, they can only go for a little distance in the direction they want before going the direction that the current takes them. That's the difference between plankton and nekton.
