The small bracelet circle should appear to stand forward and the larger behind the letters. If using the reversible spectacles and the red lens is over the left eye instead of the right, this position is reversed, and so is the eyes' relationship to lines 4 and 6. Line 4 is seen only by the left eye, and line 6 is seen only by the right eye, these are the suppression checks. The other lines are seen by both eyes.
