8. Quality assessments are defined as those that establish the performance of systems under optimum conditions. Impairment assessments are used to study the systems subjected to nonoptimum conditions such as error-prone transmission and emission
9. Punctum proximum is defined as the nearest viewing distance, which is subjectively determined by the viewer's eyes for optimum accommodation to a given display.
