I use 5 eye supports and two involve homeopathic remedies. And wear sun glasses when outdoors and I'm 81 and my eyes are in good shape.

What I use :
Vit C
Grape Seed Extract
Lutein
Cineraria Maritma for cataract prevention
Simalasan for Dry Eyes -- homeopathic

You may want to start with a couple and go from there.
