vitamin A

This vitamin A plays a really big part in eyesight. It's great for night vision, Vitamin A helps you see in color, too, from the brightest yellow to the darkest purple. In addition, it helps you grow properly and aids in healthy skin.

meh... prefer my vitamin MMJ.. lets me see better at night during the day & whilst I sleep..

Just eat healthy natural food as much as possible.... Hash oil is best for keeping the body healthy too.
