Vitamin B12 Deficiency: Symptoms Include Disturbed Vision – ‘See Your Doctor’

Vitamin B12 nourishes your body in important ways, ranging from supporting the nervous system to helping build red blood cells. The lack of this vitamin can therefore prove to be insidious. However, your vision may break the news of a vitamin B12 deficiency.

A Medanta medical institute explains that distorted or blurry vision occurs once the lack of B12 targets your optic nerve.

Medanta shares: “This happens when the deficiency causes damage to the optic nerve that leads to your eyes.


“The nerve signal going from the eye to the brain is disrupted by this damage, leading to impaired vision.

“This condition is called optic neuropathy, and treatment with B12 supplements usually reverses the disorder.”

How To Treat Vitamin B12 Deficiency?

The course of action will depend on what is causing the condition in the first place. So treatments can vary based on what they need to accomplish.

The most common options are injections or tablets to replace the missing B12.

There are also some good food sources of vitamin B12 such as meat, salmon and cod, milk and dairy products, as well as eggs.

Since these are all animal-derived, vegan, and plant-based diets, they often struggle to meet the target for B12. But they can be helped by, for example, supplements.
