13Vitamin B12 is Beneficial to Eyesight
When you are vitamin B12 deficient, especially for a long time, you might begin to experience some nerve damage, and one of the nerves that can be affected is the optic nerve. If the optic nerves get damaged, it is a given that your eyesight will be affected, and once your sight is affected, quality of life will be affected. To prevent damage to the optic nerves and to ensure good eyesight, make sure you take enough vitamin B12, either from animal products or from supplements. [12]
