Vitamin B12 can help maintain and promote healthy eyesight. As we get older, many of us suffer from macular degeneration (loss of eyesight). In a study on 5 000 women over the age of 40, sufficient vitamin B12 intake was linked to 34-41% lowered risk of macular degeneration.
Vitamin B12 (also known as cobalamin) is an essential vitamin for neurological function. Vitamin B12 deficiency optic neuropathy is a rare complication of this deficiency that results in progressive, bilateral, painless vision loss that is often associated with reduced color vision and central or cecocentral scotomas.
B 12 deficiency-induced optic neuropathy may be reversible if identified timely. In patients with visual disturbance, B12 levels should be checked with a fundus exam. A subclinical optic neuropathy should be ruled out in B12 deficient patients.
The results showed that high doses of antioxidants vitamin C (500 mg), vitamin E (400 IU), and beta-carotene (15 mg/25,000 IU), along with zinc (8 mg), reduced the risk of vision loss from advanced age-related macular degeneration (AMD) in some, but not all, people with this disease.
Vitamin A is essential for good vision. It is a component of the protein rhodopsin, which allows the eye to see in low-light conditions.
Blurred Vision
The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision. This condition is called optic neuropathy and treatment involving B12 supplements usually reverses the impairment.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency.
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
Conclusion: daily supplementation of Magnesium in patients with POAG has shown to be of great help on reducing the rate of progression of glaucomatous functional damage, therefore improving visual function and patients' quality of life.
Taking regular breaks is key, avoiding blue light exposure in the evening, exercising regularly and eating a healthy diet can all help rest your eyes and enhance your vision health. Enjoying activities such as reading books instead of looking at screens is also beneficial for overall well-being.
Vitamin B12 is typically known for its importance in red blood cell production, DNA formation, nerve function, and metabolism, but some studies have linked a B12 deficiency to severe dry eye disease and ocular pain.
People with vitamin B12 deficiency can have neurological symptoms and/or damage without anemia (lack of red blood cells). General physical symptoms of vitamin B12 deficiency can include: Feeling very tired or weak. Experiencing nausea, vomiting or diarrhea.
Once you begin treating your vitamin B12 deficiency, it can take up to six to 12 months to fully recover. It is also common to not experience any improvement during the first few months of treatment.
A combination of vitamin B6, vitamin B9, and vitamin B12 may decrease the risk of age-related macular degeneration (AMD), the leading cause of severe irreversible vision loss in the elderly.
Age-related macular degeneration (AMD)
One large study found that women who took 1,000 mcg of vitamin B12, along with 2500 mcg of folic acid and 500 mg of vitamin B6 daily, reduced the risk of developing AMD, an eye disease that can cause loss of vision.
B Vitamins For Brain Fog
Sufficient levels of vitamin B12 are necessary to optimize nerve function, memory, and quick thinking. If you don't eat adequate amounts of shellfish, poultry, and dairy products, vitamin B12 supplements can help improve cognitive decline, poor memory, as well as muddled thinking.
Unfortunately, eyesight cannot be improved naturally and there is no way to change a refractive error, such as myopia, hyperopia, astigmatism, or presbyopia. These types of visual conditions can be treated with glasses, contact lenses, or refractive surgery. However, there can be other reasons for diminished eyesight.
The natural aging process causes changes to your eyes. Typically, these changes are associated with poor eyesight or loss of vision. Some older adults experience improved vision when the lens in their eye changes before a cataract forms. This is known as second sight, and it's only temporary.
