Dietician Helen West explained to HealthLine, a medical research website, that one of the symptoms of vitamin B12 deficiency is blurred vision or disorder.
This could happen when an untreated B12 deficiency leads to damage to the optic nerve, and thus damage can disrupt the nerve signal traveling from the eye to the brain, which weakens vision, according to West. This condition is known as optic neuropathy. Although it is alarming, it can be reversed with B12 supplementation. "
Blurred vision may affect the whole view, or small parts of the field of view.
But just because a person has blurry vision, this does not necessarily mean that he has a vitamin B12 deficiency, so the reason for blurring vision can also be cataracts, migraines, or eye injury.
The most common warning signs of a vitamin B12 deficiency include: fatigue, jaundice, and feeling dizzy.
Vitamin B12 is a critical component of a healthy body, as it is necessary for making red blood cells. Signs of deficiency can develop very slowly, so it may be difficult to diagnose the condition.
People with undiagnosed symptoms should keep in mind that they may be deficient in vitamin B12.
A rapid blood test can reveal whether more vitamin B12 should be added to diets.
And changes in vision can occur due to not getting enough vitamin B12 in the diet.
It is reported that the best sources of vitamin B12 include beef, eggs and salmon.
