It was either a life or not having the power of the ring, which made Nyx choose his in order to achieve it (as the power of the ring was required, much like Ignis required the power to face Ardyn). It makes no sense that the ring's demand get toned down to Ignis' eyesight afterwards, or that the blood price depends on the mood of the Kings.
It's even worse if you choose to sacrifice yourself in the Alternate Verse, but then Ignis actually doesn't die (and heck, he doesn't even loses his vision). They were absolutely clueless with it.
