Boric Acid Wash for Eye Infection (Conjunctivitis, Trachoma, Opthalmia)

Boric acid

Boric acid is a weak, water soluble acid available commercially in crystal or powder form, and also occurs naturally in most fruits and many other plants. An effective preservative, lubricant, and insecticide, boric acid is also useful for medical applications as an antiseptic, antifungal, an ear wash and an eye wash. Boric acid was also a major component in the original Silly Putty formula.

Boric Acid Wash for the Treatment of Eye Infection


  • Boil 1 tsp boric acid with 1 cup of water, cool, and apply to the eye with a sterile eye cup, cotton balls or washcloth. Repeat 2-3 times daily until symptoms are gone.

Why It Works

Boric acid is an antiseptic and effectively cleanses the eye, preventing the spread of the infection and easing discomfort.


Make sure anything applied to the eye is sterile. Always remove contact lenses before using the eye wash. Boric acid is generally regarded as safe in humans, particularly when applied topically. Eye infections can cause long-term damage, so contact your healthcare provider if symptoms do not improve after 2-3 days.
