Boric acid is used as an eye wash to cleanse eyes. It is used to provide a comforting relief from eye irritation. Boric acid is a weak acid of boron, it is often used as an antiseptic for minor cuts, burns and also may be used in dressings or salves. It comes in the form of white powder that dissolves in water.
- Do not wash your eyes with this solution if you’re allergic to boric acid.
- While buying boric acid from a pharmacy store, always ensure it’s for ophthalmic use only, with the pharmacist. Note: A boric acid can come in different grades for medicinal, agricultural and other uses.
- Do not use this medication if you have any open wounds or cuts around your eyes.
- Do not wash your eyes with this solution if you’re wearing contact lenses, as the preservatives in it will cause discoloration to the lenses spoiling them permanently.
- Pregnant and lactating mothers should generally avoid this medication and consult an ophthalmologist for their eye problems.
- A very very dilute solution of boric acid is used as an eye wash.
- Choose a utensil, like a wide cup or bowl big enough so that you can lower your head and immerse your eye in it and you need a spoon to mix the solution.
- Sterilize the utensils (the bowl and the spoon) by boiling it in hot water for at least 15 minutes at 121 °C or 250 °F. Please be careful to put in a utensil that is safe to boil.
- Simultaneously, boil a cupful of water in another clean utensil for 20 minutes.
- Boiling kills all forms of microbial life, including fungi, bacteria and viruses present in water.
- Let both these utensils cool down.
- Wash your hands clean. Wash your hands using soap and water or an alcohol based hand sanitizer.
- Now if the utensils have cooled down to room temperature, pour the boiled water in the sterilized container, add a pinch of boric acid that is quite less than 1/8th teaspoon in quantity to be safer.
- (Remember we want a very dilute solution, the dilution must be enough so that you don’t suffer from its side effects such as irritation or burning sensation.)
- Mix the solution with the spoon thoroughly and completely until it is uniform.
- Now pick up the bowl and bring it near to your face, bend your head lower so that your eye makes contact with the solution. Wait for a few seconds and move back and keep the container down.
- Do not repeat this procedure again, let some time pass away, note how you feel. If you felt good and soothing, that’s what this whole exercise was about “soothing your eyes”.
- Now after a while, if you have accomplished exactly as desired, without any side effects you have done well and followed right.
- Remember the “secret to success” is just a pinch or even less of a boric acid, just very very little is all you need to keep your eyes safe and fresh.
- Do wait for half an hour before putting your contacts again.
Warning: Tell your doctor right away if any of these unlikely but serious side effects occur:
- Severe burning of eyes
- Stinging eye pain
- Blurred vision
- Watery eyes that does not improve
Precaution: Boric acid is poisonous if taken internally or inhaled in large quantities.
