Temporal modulation in optometry refers to the perception of flicker or changes in light intensity over time. It is crucial for understanding visual processing and can impact how individuals perceive motion and brightness. The term lacks a formal definition, leading to confusion among practitioners and researchers. Resources like MetaCrawler suggest a connection between temporal modulation and flicker perception, highlighting its relevance in visual assessments. Understanding this concept is essential for advancements in optometric practices and visual health.
