Can You Put Saline Solution in Your Eyes? (2023)


Saline solution, commonly known as saltwater, is often recommended for individuals experiencing dry eyes or contact lens irritation. While many assume that saline solution is solely intended for eye use, it can actually be employed in various parts of the body. In this comprehensive article, we will explore the benefits and uses of saline solution beyond its original purpose. We aim to provide detailed insights on how saline solution can help maintain proper pH levels, offer hydration and moisture, clean and disinfect, prevent infection, reduce eye irritation and dryness, and keep the eyes moisturized and healthy.

Using Saline Solution to Maintain Proper pH Levels

The tear film in our eyes consists of a combination of water and mucus. When this film becomes excessively dry, it can lead to irritation and discomfort. This is where saline solution comes into play. By using saline solution, we can help maintain the proper pH level of the eye's tissues, thereby preventing irritation and discomfort. Additionally, saline solution aids in moisturizing the eyes, which is particularly beneficial for individuals who wear contact lenses.

Saline Solution as an Effective Source of Hydration and Moisture

Individuals suffering from dry eyes or those who use contact lenses can greatly benefit from the hydrating and moisturizing properties of saline solution. When saline solution is applied to the eyes, it helps maintain the normal pH level of the eye's tissues, reducing irritation and discomfort. Furthermore, it assists in keeping the eyes moisturized, which is crucial for contact lens wearers.

The Cleaning and Disinfecting Power of Saline Solution

Saline solution can be utilized to clean and disinfect contact lenses, ensuring optimal hygiene. Additionally, it can be used to irrigate the eyes in cases of sinus infections or other related ailments. By using saline solution, one can effectively prevent infection and reduce the risk of bacteria spreading from the eyes to the contact lenses. It is particularly effective for disinfecting contact lenses made of plastic or silicone hydrogel materials, as these materials are not susceptible to bacterial growth.

Preventing Eye Irritation and Dryness

The application of saline solution before or after wearing contact lenses can effectively prevent dry eyes by maintaining the tear film's moisture. This, in turn, reduces the likelihood of experiencing eye irritation and dryness. By ensuring the normal pH level of the eye tissues, saline solution helps alleviate discomfort and allows for longer periods of comfortable contact lens wear.

Mitigating Eye Irritation and Redness

Individuals who wear contact lenses or suffer from dry eyes often encounter eye irritation and redness. Saline solution proves to be a valuable resource in preventing these issues. By using saline solution before or after wearing contact lenses, individuals can significantly reduce eye irritation and redness, enabling them to wear their contacts for extended periods without discomfort.

The Importance of Eye Moisturization

Maintaining proper eye moisture is essential for overall eye health. Saline solution plays a crucial role in keeping the eyes moisturized and preventing potential complications. This is especially important for individuals who wear contact lenses, as dry eyes can lead to blurred vision and discomfort such as burning or stinging sensations.

Safety Measures for Using Saline Solution in Your Eyes

While saline solution is generally safe for use, certain precautions should be taken. It is advisable to follow these guidelines:

  1. Place a drop of saline solution in one eye.
  2. Gently blink to allow the fluid to spread across the cornea and into the tear ducts.
  3. Cover the other eye with your finger for 5 minutes to prevent leakage.
  4. Thoroughly wash your hands with soap and water before touching your eyes or face.
  5. Refrain from eating or drinking for at least 15 minutes after applying saline solution to your eyes.
  6. Avoid touching other parts of your body for at least 20 minutes after application.
  7. Wait at least 20 minutes before using any other eye drops, including artificial tears.
  8. Change the solution every 2 hours if you do not have dry eyes or if blinking is painful.
  9. Never use saline solution on the eyes of infants or toddlers, as it may result in serious eye infections.
  10. Individuals allergic to preservatives in saline solutions should avoid using them.
  11. Recent recipients of Lasik surgery or other forms of laser eye surgery should avoid using saline solution immediately after the procedure.
  12. Individuals with certain eye diseases, such as glaucoma or retinitis pigmentosa, should refrain from using saline solution.
  13. Pregnant or breastfeeding individuals should consult their doctor before using saline solution for dry eyes.
  14. Diabetic individuals should avoid using saline solution, as it may cause low blood sugar levels.
  15. Children under 6 years old should not use saline solution, as it may lead to serious eye damage or blindness.
  16. Regular use of eye drops may be necessary to maintain eye moisture and cleanliness.


Dry eyes can cause significant discomfort, but fortunately, there are numerous treatment options available. Saline solution proves to be a safe and effective method for relieving dry eye symptoms. Its versatility allows for various applications, including cleaning and disinfecting contact lenses, flushing out contaminants, and preventing dryness and irritation. Additionally, saline solution can be used on the eyelids to soothe itching, burning, and swelling associated with skin conditions such as eczema or psoriasis.

By adhering to the recommended guidelines and utilizing saline solution appropriately, individuals can experience relief from dry eyes and maintain optimal eye health. Remember, if dry eye symptoms persist or worsen, it is advisable to consult a healthcare professional for further evaluation and treatment.
