How Do You Use a Boric Acid Solution for Eye Discomfort?

To use a solution of boric acid to treat eye discomfort, Health911 suggests mixing 1 quart of boiled water with 1 tablespoon of boric acid. The mixture should be allowed to fully cool before applying a small amount with a washcloth or cotton ball three to four times daily.

Boric acid can be purchased at almost any drug store. Other application methods include using a small cup to pour a small amount of the solution over the eye or using an eye dropper. An individual should be sure to remove contact lenses before using the boric acid and to refrain from putting contact lenses back in until 15 to 20 minutes have passed, according to SteadyHealth. This solution should be used three times a day in order for it to be effective. However, an individual should discuss preparations with an eye doctor before attempting this process as an incorrectly mixed solution can make symptoms worse.

Individuals employ boric acid as an eyewash for a number of reasons. General eye irritation is one reason to use boric acid, but other reasons include treating bacterial conjunctivitis, or pink eye. Others use this wash to clean the eyes if recommended by a doctor. According to, an individual should not use boric acid if he has any cuts or open wounds around the eye.
