Dry Eye and Your Diet: Vitamins for Dry Eye Disease
Dry Eye Disease can impact your life to the point of trying anything, just to alleviate the symptoms. But if you’re looking for a real way to improve your lifestyle and overall ocular health, while helping manage symptoms of Dry Eye Disease, it might be time to look at your diet.
There are many macronutrients and micronutrients to consider if you’re trying to improve the condition, and at Dry Eye and Me, we’re Dry Eye Disease experts. Here’s everything you need to know about Dry Eye Disease and your diet, including what the best foods to eat are for Dry Eye Disease symptom relief.

What is Dry Eye Syndrome?
Dry Eye Disease is a condition that affects the layers of tears in your eyes. It’s either caused by a deficiency in the amount or quality of your tears. When your tears aren’t able to properly hydrate your eyes, it can lead to inflammation and damage to the eye’s surface.[1]
The part of your eye that’s responsible for protecting the organ (and your vision) is called the tear layer. It’s comprised of three components:
- The aqueous layer which is comprised largely of water. It’s produced by the lacrimal gland and moistens the eye as well as making antibodies.
- An oily outer layer which is produced by the Meibomian Gland. This helps to lubricate your eyes, helping you blink and stops your tears from evaporating before this process is completed.
- An inner mucus layer which I produced by gland inside the conjunctiva. This layer spreads tears across the surface of your eye, ensuring it’s properly protected, moistened, and lubricated.[2]
The three work together for these important processes and an imbalance in this can cause Dry Eye Disease and feelings of discomfort.
There are three main types of Dry Eye Disease:
- Aqueous Deficient Dry Eye which is caused by your lacrimal glands not producing enough aqueous tears.
- Evaporative Dry Eye which is when your tears evaporate too quickly, meaning they’re not able to adequately lubricate and protect the surface of your eyes. This is most commonly caused by meibomian gland dysfunction.
- Mixed Dry Eye which is where patients suffer from both aqueous tear deficiency and tear instability. Your eyes aren’t able to produce enough tears to hydrate the lens, and your tear film is unstable.[3]
What are Dry Eye Symptoms?
There are a variety of symptoms of Dry Eye Disease, and many patients will experience a mix of them. Many people with Dry Eye Syndrome report excessive watering, eye twitching, soreness, irritation, dryness, a feeling of grit in the eyes, and itchiness.[4] Those living with the disease can find wearing contact lenses uncomfortable and might find reading or working on computers difficult.[5]
How Can I Know if I Have Dry Eye Disease?
If you’re suffering with any of these symptoms, it might not necessarily mean you have Dry Eye Disease. Dry eyes and itchiness can be caused by a variety of things including reactions to certain medication, however many of the treatments for Dry Eye Disease may help your symptoms.
If you’re concerned about whether you have Dry Eye Disease you can take some basic steps to test for it. Try the Stare Test on our website. Or you can speak to your eye doctor and schedule an eye exam. They may use a tear break-up time test or a Shirmer test which uses medical paper to indicate whether your eyes produce enough tears to help maintain moisture.[6]

What are the Causes of Dry Eye Syndrome?
There’s no one singular cause for Dry Eye Disease. In fact, it an extremely common disease affecting up to 50% of all adults.[6] Older people and women are more likely to develop the condition due to hormonal factors affecting tear production and quality.[7]
Other causes of Dry Eye Disease include:
- Low humidity
- Screentime
- Blepharitis
- Contact lens usage
- Lack of sleep
- Autoimmune diseases
How Does your Diet Affect Dry Eyes?
But one of the causes of Dry Eye Disease that you might not be as familiar with is your diet. An unbalanced diet lacking in Omega-3 fatty acids can contribute to Dry Eye Disease.[8]
Omega-3 fatty acids
Omega-3 fatty acids are usually connected to heart health, helping to lower your triglycerides and support all your cells in your body to function as they should. They’re concentrated in high levels in cells in your eyes.[9]
If you’re looking to increase your intake of this essential nutrient, you can look to add more fatty fish to your diet. Mackerel, salmon, cod liver oil, and sardines are great choices.
However, there are plant-based sources of Omega-3 (specifically omega-3 fat alpha-linolenic acid) such as flaxseed, chia seeds, and walnuts. Soybeans contain many essential nutrients such as magnesium and potassium but are also a source of omega-6 fatty acids and supply 670mg of ALA in a half cup.[10]

Water
It might seem like an obvious choice but water and getting proper hydration in your diet can be beneficial for your Dry Eye Syndrome. Tears are comprised of 98% water, so to aid your body creating tears that hydrate and lubricate your eyes, you should be making sure you’re getting enough water.[11]
Caffeine
While many medical professionals would advise reducing caffeine consumption for the sake of our health, recent research has suggested that caffeine can stimulate tear production.[11]
Can Vitamins Help Dry Eyes?
Vitamins are crucial for a health diet overall, but there’s many specific vitamins that you should include in your diet if you’re looking to reduce your symptoms of Dry Eye Disease.
Vitamin A
You might have grown up hearing that saying ‘Carrots are good for your eyes’ and the theory many children have that carrots can help you see in the dark. However, there is truth in those old tales. Vitamin A helps maintain the eye’s surface and supports your overall vision. A healthy eye surface can help avoid irritation and the feelings of dryness and itchiness.[12]
You can increase the amount of Vitamin A you’re consuming by adding certain foods to your diet as well as taking additional supplements. Some foods that are great sources of Vitamin A are lamb’s liver, salmon, butter, goat’s cheese, sweet potato, kale, and carrots.[13]
Vitamin E
It’s believed that Vitamin E may help improve your overall eye health and a study recently conducted claimed that vitamin E might help improve the stability of the tear film, helping your tears to adequately hydrate the eye.[14] Plus, it protects your eyes against cell damage.
Foods that are rich in this vitamin include red peppers, almonds, pumpkin, and peanuts.
Vitamin C
Vitamin C is crucial to your eye health, but especially to those who suffer from Dry Eye Disease. It helps to maintain a functioning tear film – something you should be concerned about if you’re fighting dry and itchy eyes.
Vitamin C supplements are very common, but to include more in your diet you should look to eat more peppers, broccoli, and brussels sprouts.[15]
