How to Make Artificial Tears for Dry Eyes
Dry eyes, also known as keratoconjunctivitis sicca, is a common condition characterized by insufficient tear production or poor tear quality. This can lead to discomfort, irritation, and blurred vision. While over-the-counter artificial tears are readily available, making your own at home can be a more cost-effective and personalized solution. In this article, we will guide you through the process of how to make artificial tears for dry eyes.
Ingredients Needed
To make artificial tears at home, you will need the following ingredients:
1. Saline solution: You can use commercially available saline solution or make your own by dissolving half a teaspoon of non-iodized salt in a cup of distilled water.
2. Boric acid: This is a natural compound that helps to maintain the pH balance of the eyes.
3. Sodium borate: Also known as borax, this ingredient helps to preserve the artificial tears.
4. Glycerin: This is a humectant that helps to keep the tears moist.
5. Preservative: To prevent bacterial growth, you will need a preservative. You can use a commercially available preservative or make your own using benzalkonium chloride.
Instructions
1. Start by preparing the saline solution. If you are using commercial saline solution, ensure it is isotonic, meaning it has the same salt concentration as your tears. If you are making your own, dissolve half a teaspoon of non-iodized salt in a cup of distilled water and stir until the salt is completely dissolved.
2. In a separate container, mix 1/4 teaspoon of boric acid and 1/4 teaspoon of sodium borate in a cup of distilled water. Stir until the powders are completely dissolved.
3. Add the saline solution to the container with the boric acid and sodium borate mixture. Stir well to combine all the ingredients.
4. Add 1/2 teaspoon of glycerin to the mixture and stir until the glycerin is fully dissolved.
5. Finally, add a preservative to the mixture. If you are using a commercial preservative, follow the manufacturer’s instructions. If you are making your own, dissolve 1/4 teaspoon of benzalkonium chloride in a small amount of distilled water and then add it to the mixture.
6. Stir the mixture thoroughly until all the ingredients are well combined. Store the artificial tears in an airtight container and keep it in the refrigerator.
Using Your Homemade Artificial Tears
To use your homemade artificial tears, simply instill a few drops into your eyes as needed. Be sure to wash your hands before applying the drops to avoid introducing bacteria into your eyes. If you experience any discomfort or irritation after using the artificial tears, consult your eye doctor.
Making your own artificial tears for dry eyes can be a convenient and cost-effective solution. By following the steps outlined in this article, you can create a personalized tear substitute that meets your specific needs.
