Answer

Converging.

Work Step by Step

We know that the index of refraction of the human eye cornea is about 1.367 to 1.380 while the index of refraction of the water is 1.333. This means that these two indices of refractions are similar which means that there will be a little refraction at the water-cornea boundary. So to fix this little refraction, we need to use a converging lens. Thus, we need to use glasses with converging lenses.
