Why can nearsighted people see better underwater than people with 20 20 vision?
When light changes from traveling in one medium to another, it will 'bend' or refract. However, water and your eye basically have the same refractive index, so the light will barely bend (unlike in air.) Your lens can't properly compensate for the lack of the refraction, so a normal person would become more farsighted, a farsighted person would become even more farsighted. However, a severely nearsighted person would get closer to normal as their eye defects compensate more for the lack of refraction.

Farsighted people typically require convex lenses to help them see objects up close more clearly. These lenses are thicker in the center than at the edges, helping to bring close-up objects into focus for those with farsightedness. An eye examination by an optometrist or ophthalmologist can determine the specific lens prescription needed.
