ASTIGMATISM TEST

WHAT DOES THIS TEST CONSIST OF?

Astigmatism is a refractive defect that causes a distorted vision of objects at any distance. The most frequent cause of astigmatism is a corneal irregularity. This test allows us to find out if a patient has astigmatism as well as to place it on its axis.

HOW TO CARRY OUT THE ASTIGMATISM TEST

Please place yourself about a metre away from the screen. Cover one eye and stare at the figure. Observe if any of the lines shown underneath appear sharper than the rest of them. Cover the other eye and repeat the exercise.

ASTIGMATISM TEST RESULTS

If all lines appear equally sharp to you, apparently you haven’t got astigmatism. If a line appears sharper than the other ones do, you probably have astigmatism. The higher is your astigmatism degree, the worse you will see the other lines. Should you observe any line that appeared sharper than the other ones did after carrying out the test, we advise you having your eyes tested by your ophthalmologist so that he gives you a proper diagnostic and treatment for your refraction defect.
