In the visual function, the zinc participates in vitamin A metabolism, making the retina. The retinal synthesis zinc deficiency in vitamin A reduction enzyme activity is restricted which may appear nyctalopia retinal and pigment membrane's metabolism. The lack of zinc will inevitably affect visual function. The zinc can restrain the corneal perforation, pseudomonas protease activity, reduces or avoids eyeball perforation and so on. In a word, zinc is so important for the eye vision.
