WEBStep 3: Stand back from the Amsler Grid so that your face is about 12 to 14 inches away from the grid. Now, cover your right eye and look at the black dot in the middle of the left grid with your left eye open (with your eye fixated on the black dot). Use a pen or pencil to mark any areas where the lines appear missing, broken, crooked or wavy.
