The primary vitamin used in eye lubricants, especially ointments for dry eyes, is Vitamin A (Retinol Palmitate), which supports the eye's surface, helps form the tear film, and protects against dryness and infection, with products like VitA-POS eye ointment containing it to create a lubricating barrier. Other vitamins like B12, C, and E also support overall eye health and lubrication, but Vitamin A is the key one in specific lubricating treatments.
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.
Vitamin A deficiency, which usually occurs in developing countries, can cause an increase in dry eye. By adding foods rich in Vitamin A, like carrots, pumpkins, apricots, spinach, tomatoes, dairy products and liver, you can prevent the development of this condition.
There is no specific recommended dosage of vitamin B12 for dry eye symptoms. Additionally, how much one should take depends on their ability to absorb it. Doses of 2,000 micrograms are usually considered safe, but you should still speak with our eye care professional before taking vitamin B12 for dry eye.
Eat (Naturally) Oily Fish
Research suggests these healthy fats help the oil-making glands in your eye work better, which can ease irritation. Other foods naturally high in omega-3 fats include walnuts, vegetable oils (like canola and soybean oil), and flaxseed. You can also take omega-3 fatty acids as a pill or tablet.
Adding omega-3 fatty acids to your diet may help relieve dry eye signs and symptoms. These are available as supplements and in foods such as flaxseed, salmon and sardines. Castor oil eye drops. These eye drops may improve symptoms by reducing tear evaporation.
Anti-Inflammatory Medications
Your ophthalmologist may recommend closporine, a medicated eye drop designed for long-term use, if you have severe dry disease, or an autoimmune condition, such as Sjögren's Disease or systemic lupus erythematosus. Cyclosporin can help decrease inflammation caused by these conditions.
If you look paler than normal, or have a subtle yellow tinge to your skin and the whites of your eyes, you could have a vitamin B12 deficiency. This is because the vitamin is important for your red blood cells. When red blood cells are not able to divide, you can get a type of anaemia called megaloblastic anaemia.
Magnesium is a mineral known for reducing inflammation and enhancing overall immune function. Research indicates that magnesium supplementation may help alleviate dry eye symptoms by improving tear quality. Foods high in magnesium include almonds, spinach, and avocado.
Warning signs of vitamin B12 deficiency include extreme fatigue, weakness, pale/yellow skin, numbness/tingling (pins and needles), cognitive issues (memory fog, confusion), mood changes (depression/irritability), and a sore, red tongue, alongside potential shortness of breath, heart palpitations, and balance problems, as symptoms develop slowly and can worsen over time. It's crucial to see a GP, as early treatment prevents potentially irreversible neurological damage, say NHS, Cleveland Clinic, and WebMD.
Reasons for tear film dysfunction are many, including hormone changes, autoimmune disease, inflamed eyelid glands or allergic eye disease. For some people, the cause of dry eyes is decreased tear production or increased tear evaporation.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
Vitamin A, also known as retinol, produces the pigments in the retina of the eyes. More importantly, it is a vital nutrient for the photoreceptors in your eyes, which determine vision quality in low-light conditions.
Mango and papaya are full of nutrients that help support healthy eyes. Two key nutrients are the antioxidants lutein and zeaxanthin. These act as a natural sunblock, absorbing excess light coming into the retina. They also protect the eye from harmful blue light.
Eye drops: There are many different types of eye drops. Artificial tears lubricate and soothe your eyes, temporarily relieving symptoms. They're available over the counter. Ointments: If your eyes dry out while you sleep, you can use a thicker lubricant at night, like an ointment.
Fish oil has many advantages, both for developing vision and maintaining healthy eyes at any age. The omega-3 fatty acids found in fish oil provide nutrition that can even reduce the risk of eye diseases such as macular degeneration.
Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms. A blood test or urine test can be used to diagnose magnesium deficiency.
Vitamin B12
According to a 2017 study, a B12 deficiency is associated with severe dry eye and eye pain. A recent 2015 study found that the combination of oral vitamin B12 supplements and artificial tears improved symptoms of dry eye syndrome.
A deficiency in magnesium has been linked to poor tear production, increased eye inflammation, and higher risk of oxidative stress, which can worsen dry eye symptoms. Taking a bioavailable form such as magnesium glycinate helps restore balance and optimize eye hydration.
Cutaneous manifestations associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. A diagnosis of vitamin B12 deficiency is often overlooked in its early stages because these signs are not specific to vitamin B12 deficiency alone.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes.
Vitamin B12 is abundant in animal products like meat (especially liver), fish (salmon, tuna, sardines), poultry, eggs, and dairy (milk, yogurt, cheese), with fortified foods such as cereals, nutritional yeast, and plant milks offering options for vegetarians and vegans, as plants don't naturally contain B12.

The 10-10-10 rule for eyes is a simple strategy to combat digital eye strain: every 10 minutes, take a 10-second break and look at something at least 10 feet away, giving your eyes a rest from near-focus on screens. This practice helps prevent eye fatigue, dryness, and headaches by allowing eye muscles to relax and encouraging blinking, which is often reduced during screen use, says Healthline and Brinton Vision.
