Scientific Explanation of Dry Eyes

Dry eyes, medically known as keratoconjunctivitis sicca, is a common condition that occurs when the eyes are unable to produce enough tears or when the tears evaporate too quickly. It is a chronic condition that affects millions of people worldwide, causing discomfort, irritation, and vision problems.

The tear film, which covers the surface of the eyes, is made up of three layers: the aqueous layer, the lipid layer, and the mucous layer. The aqueous layer is the thickest layer and is responsible for providing moisture and oxygen to the cornea. The lipid layer, which is produced by the meibomian glands, helps to prevent evaporation of tears. The mucous layer, which is produced by goblet cells in the conjunctiva, provides a smooth surface for the tears to spread over. Any imbalance or deficiency in these layers can cause dry eyes.

Several factors can contribute to the development of dry eyes, including aging, hormonal changes, certain medications, environmental conditions, and underlying health conditions such as autoimmune disorders.

Causes of Dry Eyes

Dry eyes, or keratoconjunctivitis sicca, occurs when the eyes do not produce enough tears or when the quality of tears is poor. Dry eyes can be caused by a variety of factors, including:

  • Age: As you get older, the production of tears decreases, and the quality of tears may not be as good as when you were younger.
  • Environmental factors: Dry air, wind, smoke, and other environmental factors can cause tears to evaporate quickly, leading to dry eyes.
  • Medical conditions: Certain medical conditions may cause dry eyes, such as Sjogren’s syndrome, rheumatoid arthritis, and diabetes.

Symptoms of Dry Eyes

The symptoms of dry eyes may vary depending on the severity of the condition, but some common symptoms include:

  • Burning or stinging sensation
  • Redness of the eyes
  • Blurred vision
  • Sensitivity to light
  • Eye fatigue

Treatment Options for Dry Eyes

The treatment for dry eyes may depend on the cause and severity of the condition. Some treatment options may include:

  • Artificial tears: Over-the-counter or prescription artificial tears can help lubricate the eyes and relieve the symptoms of dry eyes.
  • Medications: Some medications may help increase tear production or decrease inflammation in the eyes.
  • Surgery: In severe cases, surgery may be an option to help increase tear production or close the tear ducts to keep tears from exiting the eye too quickly.

Is Salt Water Good for Dry Eyes?

While salt water may provide some relief for dry eyes, it is not a recommended treatment option. Salt water may irritate the eyes and cause further dryness, especially if the salt concentration is too high. It is best to consult with an eye doctor to determine the best treatment option for your dry eyes.

Salt Concentration Effect on the Eyes
0.9% Safe for use in the eyes
3% May cause irritation and further dryness

Overall, it is important to take care of your eyes and seek medical attention if you experience symptoms of dry eyes. Your eye doctor can help determine the cause of your dry eyes and provide the best treatment options for your individual needs.

Can Salt Water Be Good for Dry Eyes?

Some people may believe that saltwater can be beneficial for dry eyes. However, there is limited scientific evidence to support this claim. Saltwater may help to relieve some of the irritations associated with dry eyes, but it is not a proven treatment for dry eyes. In fact, saltwater may aggravate dry eyes and cause more irritation. It is always best to talk to an eye doctor before trying any home remedies or treatments for dry eyes.

Pros of Saltwater for Dry Eyes Cons of Saltwater for Dry Eyes
May help relieve some symptoms of dry eyes May cause irritation and aggravate dry eyes
Does not require a prescription May not be effective for severe cases of dry eyes
May provide a temporary solution for mild cases of dry eyes May not be safe for individuals with certain conditions

Overall, saltwater may provide temporary relief for mild cases of dry eyes, but it is not a substitute for proper medical treatment. An eye doctor can provide a proper diagnosis and recommend the most appropriate treatment plan for dry eyes.

Conventional Treatments for Dry Eyes

Conventional treatments for dry eyes are the most common and widely used methods to manage the symptoms of dry eye disease. These treatments aim to restore the normal lubrication and moisture in the eyes by reducing inflammation, promoting tear production, and preventing tear evaporation. Here are the most common conventional treatments for dry eyes:

  • Artificial Tears – Over-the-counter eye drops containing lubricants that mimic the natural tears of the eyes, providing instant relief from dryness, redness, and burning sensation. They come in different formulations, including preservative-free, gels, ointments, and lipid-based drops. The frequency of use varies from person to person and the severity of the condition.
  • Anti-Inflammatory Medications – Prescription drugs such as corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate inflammation in the eyes, which is a common cause of dry eye. These medications come in the form of eye drops, pills, or injections.
  • Punctal Plugs – Small medical devices made of silicone or collagen that are inserted in the tear ducts to block the drainage of tears, thus increasing their retention time in the eyes. This helps keep the eyes lubricated and moist for a longer time.

These treatments are often used in combination with each other, depending on the severity and underlying cause of the dry eye disease. A doctor may also recommend lifestyle changes such as avoiding dry environments, using a humidifier, and taking breaks during prolonged screen time to reduce eye strain.

However, it is important to note that conventional treatments just manage the symptoms of dry eye rather than cure the root cause of the problem. Chronic dry eye disease requires continuous management and monitoring to prevent further damage to the eyes.

Let’s explore some natural remedies and alternative therapies in the next subsection that may benefit people with dry eye disease.

Natural Remedies for Dry Eyes

Dry eyes can be a nuisance and cause discomfort for many people. While there are over-the-counter and prescription options available to treat dry eyes, some people may prefer to try natural remedies first. Below are five natural remedies that may provide relief for dry eyes.

  • Omega-3 Fatty Acids: Studies suggest that omega-3 fatty acids may reduce inflammation and promote tear production in individuals with dry eyes. Foods rich in omega-3s include fatty fish, flaxseed, and chia seeds.
  • Blinking Exercises: People who work on a computer for extended periods may not blink as frequently, which can lead to dry eyes. Blinking exercises, where you close your eyes tightly for a few seconds then open them slowly, can help to increase tear production.
  • Warm Compresses: Applying a warm compress to your closed eyes for 10-15 minutes can help to open up oil glands in your eyelids, which can improve tear quality and reduce dryness.
  • Humidifier: Adding humidity to the air in your home or office can help to reduce dryness in the eyes. A humidifier can add moisture to the air and may also help to reduce symptoms of dry skin and nasal passages.
  • Green Tea: The antioxidants in green tea have been shown to help reduce inflammation and promote tear production. Drinking green tea may also have other health benefits, such as reducing the risk of heart disease and stroke.

Other Natural Remedies

In addition to the remedies mentioned above, other natural remedies for dry eyes include using castor oil eye drops, avoiding air conditioning or fans blowing directly on your face, and increasing your water intake to stay hydrated. It’s always a good idea to talk to your doctor before trying any natural remedies, especially if you have any underlying medical conditions or take medications.


While natural remedies can be effective for relieving symptoms of dry eyes, they may not work for everyone. It’s essential to speak to a doctor to determine the underlying cause of your dry eyes and the best treatment options for you. With proper treatment, you can find relief from dry eyes and improve your overall eye health.

  • Reduces inflammation: Dry eyes are often accompanied by inflammation, which can be extremely uncomfortable. Saltwater has anti-inflammatory properties that can help reduce swelling and redness, providing relief to the eyes.
  • Flushes out debris: Salt water can be effective in removing debris and irritants that may be present in the eyes. It can clear out any dirt, dust or other particles that may be causing the dryness.

There are several ways to use salt water for the treatment of dry eyes:

You can prepare a saltwater solution at home by mixing a teaspoon of salt in a cup of warm water. Use a dropper to drop a few drops of this solution into each eye, or use it as a wash by soaking a clean cloth in the solution and placing it over your eyes. Repeat this process a few times daily, or as recommended by your doctor.

If you prefer a ready-made solution, you can buy saline eye drops over-the-counter, which often serve as a good alternative to homemade saltwater solution. Make sure to choose the ones that are preservative-free as they are less likely to irritate the eyes.

Saltwater vs Regular Water for Dry Eyes

Salt water is a better alternative to regular water when it comes to treating dry eyes. Tap water is often treated with chlorine and other chemicals that can irritate the eyes, making them drier. On the other hand, salt water has been found to be a mild and natural option that can provide relief to the eyes without any adverse side effects.

Precautions to Take While Using Salt Water

While salt water is generally safe to use, there are a few precautions you should keep in mind:

  • Do not use salt water if you have an eye infection or any other injury to the eye. Consult your doctor for treatment instead.
  • Always use sterilized or distilled water when making your own salt water solution to avoid contamination that could lead to infection.
  • Do not use salt water excessively as it could worsen dryness in some cases. Stick to the recommended usage and check with your doctor if you have any concerns.

Overall, salt water can be an effective and natural remedy for dry eyes that can provide relief to the eyes without any side effects. Consult your ophthalmologist to understand whether salt water could be the right treatment for you.

In addition to these risk factors, it is important to note that salt water should not be used as a long-term treatment for chronic dry eyes. While it can provide short-term relief, frequent use can actually worsen dry eye symptoms and cause further damage to the eyes.

If you are experiencing chronic dry eyes, it is best to consult with an eye doctor who can recommend a personalized treatment plan to address the underlying cause of your condition. This may include prescription eye drops, dietary changes, or other interventions.


While salt water can be a helpful home remedy for mild cases of dry eyes, it is important to use it safely and responsibly.

  • Use only sterile water and salt: The salt water solution should be made with distilled or sterile water, and table salt or sea salt should be used. Avoid using water from the tap or ocean as it may contain impurities or bacteria that could harm your eyes.
  • Do not use too much salt: Using too much salt can make the solution too concentrated and cause discomfort or irritation. The ideal ratio is one teaspoon of salt per liter of water.
  • Be careful with the temperature: The solution should be lukewarm or at room temperature. Using water that is too hot or cold could affect your eyes and cause discomfort.

In addition to these precautions, there are also some situations in which using salt water for dry eyes may not be advisable:
