"Mine Eyes Dazzle," by M.K. Waller, in Dark of the Day, edited by Kaye George, Down and Out Books, 2024.
As you probably know by now, I read a lot of short stories. I seldom take the time to reread one of them, but I did this one. You might wind up doing the same.
Stephen is a blind lawyer, in his late forties. Jean is his paralegal, almost a decade younger. When they get married they declare the relationship a miracle, and it seems to be.
Until another miracle occurs; this time of the medical variety. An experimental surgery provides Stephen with sight for the first time. Suddenly he doesn't need Jean as he did before.
Things happen. One of them is a total eclipse of the sun. And that's all I will tell you about this clever story.
