1. I think this black covering is used as the same purpose as making the inside of a camera black so that it cannot reflect the light many times and also only let light that comes through the pupil to be focused on the retina.
2. I think it is vitamin A that is related with the eye. Lack of vitamin A could cause night blindness. Food that contains vitamin A such as egg yolks, butter, cheese, liver, carrot, sweet potato, milk, mango, and spinach is good for the eye. I also heard that vitamin B2, C, D, and E influence the health of our eyes.
