Full Answer

Boric acid readily dissolves in hot water. Reference.com recommends 1/4 teaspoon of boric acid powder per pint of water for mild infections, with severe infections requiring 1 teaspoon per 4 ounces of water. A clean sterile eyewash cup works well for applying the solution to the eye. The more diluted solution also is effective at rinsing foreign objects from the eyes. Boric acid eye wash is effective at removing pollutants, including chlorine, smog and other chemicals.

Drugs.com warns consumers against using this solution if they have allergies to boric acid. In addition, the solution is not advisable for use if there are cuts or open wounds around the eye. It is not for internal use. Before using the solution, it is important to remove any contact lenses. The individual should not reinsert the contact for at least 15 minutes after using the solution. Commercially prepared solutions sometimes use preservatives that cause permanent discoloring of the lens. If the problem persists, the individual should seek medical attention.
