Being deficient in Vitamin D can also have a negative impact on eye health.
Ocular manifestations could be a sign of underlying nutritional deficiencies such as vitamin A, B1, B12, C, D, and E. Using nutritional supplements such as multi-vitamin tablets may help in addressing ocular symptoms and complaints.
Without enough vitamin A, your eyes cannot produce enough moisture to keep them properly lubricated. Vitamin A deficiency is the leading cause of preventable blindness in children worldwide. An estimated 250,000 to 500,000 children become blind every year because of vitamin A deficiency.
A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as: vision problems. memory loss. pins and needles.
Vitamin B12 deficiency can also cause symptoms that affect your brain and nervous system (neurological symptoms), including: numbness. muscle weakness. psychological problems, which can range from mild depression or anxiety, to confusion and dementia.
In the case of magnesium deficiency, a large amount of calcium is excreted from the body in the urine, and thus the magnesium deficiency is also indirectly responsible for calcium deficiency. Also, low level of potassium has been associated with magnesium deficiency. Blurred vision.
Being deficient in Vitamin D can also have a negative impact on eye health. Vitamin D deficiency has been associated with conditions such as age-related macular degeneration, diabetic retinopathy, uveitis, dry eye syndrome and impaired tear function.
Common causes of eyestrain include: Looking at digital device screens. Reading without pausing to rest your eyes. Driving long distances and doing other activities involving focusing for a long time.
If you look at bright light or spend time in a place that's too dim, it can also tire your peepers. Your eyes might get tired easily if you stare for long periods at a computer, smartphone, or game console. The eye doctor might call this computer vision syndrome or digital eye strain.
Why are my eyes tired all the time? Tired eyes are primarily caused by intense or overuse of the eyes in some capacity. Staring at computer screens, televisions and mobile devices is a major cause of ongoing eye fatigue. Americans spend as many as 12 hours a day staring at screens!
Vitamin A and vision make potent allies. Carrots contain lots of beta carotene and Vitamin A, which can contribute to your eyes' health and may provide a fantastic source of eye vitamins for macular degeneration and cataracts. Good sources of Vitamin A and rhodopsin are also abundant in carrots.

Headaches. Nighttime leg cramps. Numbness or tingling in the legs or hands. General body weakness.
Vitamin B1
Vitamin B1 (thiamine) is a key “anti-stress” vitamin for its ability to decrease inflammation. Studies suggest vitamin B1 may also help prevent diabetic retinopathy — progressive damage to the retina caused by high blood sugar and decreased blood flow.
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 deficiency
Opticians can see changes in the retina such as Bitot's spots which appear as bubbly, foamy patches on the conjunctiva. This is an indication of low vitamin A levels. If a patient is lacking vitamin B12, they may suffer from changes in the optic nerve which can lead to vision problems.
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.
There are certain foods that also need a cut-down in case of vitamin B12 deficiency. “Some foods and drinks can interfere with vitamin B complex intake like alcohol, caffeine and processed foods, etc should be avoided completely,” Shah added.
Several commercially available test kits allow you to collect a sample for vitamin B12 testing at home. Some kits test only your vitamin B12 level. Others test B12 in combination with other vitamins, and there are at-home micronutrient test kits that include B12 in the panel.
