Can you see clearly underwater?

You can’t see well underwater because the water mostly cancels the focusing effect of the eye lenses. A lens is formed by having a curved surface between two media of different refractive index. A drop of water makes a lens, because of the different refractive index of water vs. air.

How can you see underwater without hurting your eyes?

Squint, rather than opening your eyes completely.

Why we Cannot see in water?

Can you see in salt water?

You can’t see really well in saltwater, but you do see better than in fresh. The Refractive Index of salt water interferes less than than fresh with the light coming into your eyes. The more saline the water, the better. The only time you might feel any stinging is when you blink a few times right after surfacing.
