Since I crossed the age of 40 milestone nearly two years ago my vision has changed. I started wearing progressives at 38 because my eyes could no longer adjust from a computer screen to across the room. I saw the link to this article in Glamour on twitter. It is worth a read. I already include many of these foods and vitamins in my diet. My late husband could not see well to drive at night even though he had blue eyes. I suspect a lack of the nutrients was a factor.
