How do I know if visual fatigue is affecting learning?

Visual fatigue may show up as looking away, closing eyes, increased blinking, reduced accuracy, decreased attention, frustration, changes in regulation, moving closer, or needing longer processing time.

Teams should look for patterns across time of day, visual complexity, lighting, distance, movement, sensory demands, and task duration. The goal is to support meaningful engagement, not simply require more looking.
