Why is human vision blurred underwater?
So, when we open our eyes underwater, incoming light rays are hardly bent, or focused, at all. The inside lens bends the rays a little, but it can’t make up for the lost corneal refraction, so the light that reaches the retina isn’t focused and the underwater world looks blurry.
