Dry, scratchy eyes have a way of turning simple things, like reading, screen time, or even a short drive, into a struggle. It’s tempting to blame seasonal allergies, the weather or a long day at your desk, since sometimes that really is the culprit.
But what you eat can play a bigger role in eye comfort than most people expect. Certain vitamins, including omega-3 fatty acids, vitamin A, vitamin D, B12, E, and C, can support tear production and help ease dry eye symptoms when paired with steady daily habits and in-office care.
What Dry Eye Means for You
To understand why nutrition matters, it helps to know what’s happening on the surface of your eye.
The tear film is essential for clear, comfortable vision. The tear film is composed of 3 layers that cover the eye every time you blink. The base layer is mucous, the middle layer is aqueous (water), and the top layer is composed of a thin oil layer that prevents evaporation.
When tears evaporate too quickly, you might start to feel a burning or scratchy sensation. This is especially common when screen time is involved or towards the midafternoon or end of the day. Since the tear film is evaporating, the eyes may water as a response since the oil layer is no longer in place. Dry eyes that are watery seem counterintuitive to most patients and often get mistaken for allergies.
By treating dry eyes early in the disease process can protect your eye’s surface while keeping everyday tasks, like reading and driving, comfortable.
Signs Your Eyes Might Be Dry
Dry eye symptoms can show up in various ways throughout the day. Pay attention to these signs:
- Redness, stinging, or a gritty feeling like sand in your eye
- Blurred vision that fluctuates with blinking
- Sensitivity to light
- Contact lens intolerance
What Causes Dry Eye
With our modern lifestyle and demands of screen time, there are many factors that can cause dry eyes. Age plays a role, as tear production tends to slow as you get older. Certain medications, such as antidepressants and antihistamines, can dry things out too.
Long hours at a screen also matter. Most people don’t realize that the blink rate actually decreases when you are using your phone or computer which causes your tears evaporate faster. Other factors, like changes in hormones (perimenopause and menopause), environment (dry air, wind), previous eye surgery (LASIK, cataract surgery) and certain eye drops that treat glaucoma, have harsh preservatives which can exacerbate symptoms. How Nutrition Supports Eye Health
Your body and eyes require specific vitamins to make healthy tears and keep the surface comfortable and smooth. Patients who have a diet deficient in essential nutrients can have dry eye symptoms that worsen over time.
I recommend keeping nutrition simple – a plate of whole foods (fish, leafy greens and veggies) give not just your eyes but your entire body the nutrition it needs to function well. You may have heard this before, but keeping to the perimeter of the grocery store is best since that’s where most of the less processed food items are located. Supplements are also beneficial to fill in the gaps in your diet as well.
Top Vitamins to Ease Dry Eye Symptoms
There are a few vitamins and supplements that we recommend for supporting tear production and everyday eye comfort.
Omega-3
Omega-3 fatty acids support the tiny oil glands, called Meibomian glands, that are located along your eyelids. This oil is essential to preventing the tear layer from evaporating too soon. Omega-3s are found in salmon, tuna and other fatty fish.
Vitamin A
Vitamin A helps your eyes produce quality tears that coat the surface evenly. Carrots and sweet potatoes are a good source.
Vitamin D
Vitamin D can help calm inflammation on the surface of your eyes, which may ease that raw, irritated feeling. Salmon and eggs both carry a good amount.
Vitamin B12
Vitamin B12 supports the repair of the cornea, the clear front layer of your eye. Eggs and red meat are solid sources.
Vitamin E
Vitamin E comes from nuts and seeds, and it helps guard the cells in your eyes against everyday wear.
Vitamin C
Vitamin C is found in citrus fruits and bell peppers, and it works alongside vitamin E to protect your eyes over time.
Simple Habits That Can Help at Home
Small daily habits can make a real difference. Try these steps to keep your eyes comfortable:
- Drink water throughout the day to stay hydrated.
- Follow the 20-20-20 rule: look at something 20 feet away for 20 seconds every 20 minutes
- Run a humidifier at home
- If you wear contact lenses, do not sleep in them
- Wear wraparound glasses on windy days
In-Office Treatments
When home care needs backup, your optometrist can offer options based on your needs:
- Prescription and lubricating drops to add moisture and calm irritation
- Intense pulsed light (IPL) and radiofrequency treatments, which target the oil glands along your lids
- Radiofrequency (RF), which targets stubborn blocked Meibomian glands
- Autologous serum tears, which provide healing growth factors to promote corneal healing. Ask your optometrist which option fits your symptoms best.
