Bright Form Rehmannia - Ming Mu Di Huang Wan

This product is ok, I prefer another brand which seems noticeble to be more effective in my opinion, without my opthamologist knowing this is what I'm taking to help with my vision, he was surprised by my visual field test that my eyes have improved unexpectedly and said wow, I've never seen this type of progress before! Keep doing whatever it is you're doing!! Yay me!
