They found the normal physiological pH of ocular surface in humans to be 7.11±1.5. They also showed an increase in ocular surface pH early in the morning and a gradual increase in pH to more alkali levels during the day. Additionally one hour of lid closure causes decrease in pH.

How do you apply pH paper to your eyes?


  1. If available, use pH indicator strips or litmus paper to assess the acidity / alkalinity of the tears caused by the injury.
  2. Take two small strips and, with these, gently touch the inside of each lower eyelid.

How would you properly measure pH?

The most precise of the 3 test options, pH meters measure a solution’s pH by measuring the electrical potential difference between the pH electrode and a reference electrode. The meter then coverts this potential to a pH reading.

What is used to measure pH?

PH meter
PH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. Fundamentally, a pH meter consists of a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode.

What does a pH test show?

The BravoTM pH test measures the pH level of your esophagus. The pH level of a substance tells whether something is basic or acidic. Sometimes, stomach acid backs up into the esophagus (the tube that connects the throat to the stomach, or the “food pipe”) which can increase the acidity level within your esophagus.

What should the pH of the eye be?

The pH of the eye is normally neutral (7.0 to 7.3). It is important to neutralize the chemical and return the pH to neutral to avoid further eye injury . The pH is tested to help determine if the eye has been irrigated enough to remove the chemical.

What should the pH be on a urine dipstick?

Gently touch the strip to the patient’s eye. Be careful of the sharp edges on the trimmed dipstick strip when touching the patient’s eye. Note that a urine dipstick can only detect a pH range of 5-8.5. Anything outside these ranges will require the eye pH paper, which can detect a range of 1-14.

What’s the trick of the trade for measuring eye pH?
