I’ve dealt with this problem all my life – i have high powered glasses (-6 and – 8, with some cylindrical /spherical tweaks). My glasses work great. But i wore them while swimming in the crystal blue Mediterranean, and when I’m diving in, i realized the glasses aren’t effective. I understand the wavy reflective patterns interrupting, but why cant I focus on anything easily?

Water is not air
No mater how “crystal blue” the water appears; it’s still not air.
Water is denser; reflects/refracts light differently
You can see for miles looking out across the horizon; in even the clearest water only a few dozen meters
