Definition of contact lens hysteresis

WebHysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the … WebHysteresis is the term used to describe the time-dependent dissipation of thermal (heat) energy from a viscoelastic material [26].It measured as the difference in area under a stress-strain curve as the specimen is loaded versus when it is unloaded. The specific value of hysteresis is a function not only of the applied load, but also all previously applied loads …
