Superstition

I'm not superstitious by any means, but when I'm taking eye pressures, and the patient is a pain in the ass, I'll record 13 mm Hg if it is 12 or 14.

Man do I wish I knew what you were talking about.

You see those green semicircles in the center of the photo? Those are created by using a dye and applying a plastic prism to the eye. You then adjust a knob that applies more or less pressure against the cornea. When the pressure is equalized, the semicircles should be aligned as you see... just overlapping... but it is slightly subjective.
