Zinc plays an important role in vision, as it is an essential component of the protein called rhodopsin, which is present in the cells of the retina of the eye.
Rhodopsin is a photosensitive protein that is activated when light enters the eye. When rhodopsin is activated, it triggers a cascade of chemical reactions that generate an electrical signal that is transmitted to the brain for visual interpretation.
Zinc is necessary for the formation of rhodopsin and its optimal functioning. Without zinc, rhodopsin cannot form properly, which can lead to vision problems, such as night blindness.
In summary, zinc is an important nutrient for eye health and vision because it is necessary for the formation and function of rhodopsin, the light-sensitive protein responsible for detecting light in the retina of the eye.
