What's the difference between pressure and tonometry?
Pressure
Definition:
(n.) The act of pressing, or the condition of being pressed; compression; a squeezing; a crushing; as, a pressure of the hand.
(n.) A contrasting force or impulse of any kind; as, the pressure of poverty; the pressure of taxes; the pressure of motives on the mind; the pressure of civilization.
(n.) Affliction; distress; grievance.
(n.) Urgency; as, the pressure of business.
(n.) Impression; stamp; character impressed.
(n.) The action of a force against some obstacle or opposing force; a force in the nature of a thrust, distributed over a surface, often estimated with reference to the upon a unit's area.

Tonometry
Definition:
(n.) The act of measuring with a tonometer;
(n.) measurement of tension, esp. the tension of the eyeball.
Example Sentences:
