Anyone who has ever been examined by an ophthalmologist has probably undergone a rather unusual procedure.
Its essence is that the doctor, using a special device called a non-contact tonometer, suddenly blows directly into the patient’s eye.
This action looks more like a joke than an eye test, so we suggest you find out why this technique is used in a medical examination.
It turns out that this is how you can determine the pressure of the fluid inside the eyeball.
You should not refuse the test, as high eye pressure can cause glaucoma or lead to vision loss.
The procedure usually does not cause any difficulties.
You are required to place your chin on the rest and look at the green light while the doctor directs air onto the surface of the eye.
The machine will measure the amount of air that has returned and determine the intraocular pressure.
