If you put your fingers on the keys, close your eyes and write the thoughts you find lurking inside your head, you may be surprised at what emerges onto the page. Sight affects what our inner voice says.
I drove someone home after a meeting recently and she said, “I’m having eye surgery soon. Once my eyes are fixed I’ll be able to hear better.” She wasn’t joking.
I would expect it to be the other way around—that when our eyes don’t work as well we depend more on our hearing. But she pointed out that what she sees supplements what she’s hearing, so if she sees better, she hears better, too. It makes sense in a peculiar way.
Have you tried writing with your eyes closed? What difference did it make?
