I have recently been looking into this. Bilberry is supposed to be good. Any variety dark fruits or vegetables too. Gingko is supposed to help. Eyebright is overrated.
What I read is that you take care of your liver health first. Give it foods & herbs that will repair and strengthen it, making it more able to do its job.
You need herbs that will open capillaries and help circulation late blood to extremities, especially to the brain, as well.
Right now, I am making a tincture of gingko, gotu kola, rosemary & peppermint. This is supposed to help the brain function better, and from what I read, should help my eyes to some extent then as well.
I am still learning what I can do. What I have mentioned here is in no way exhaustive, but is a start.
