Flicker

Flicker refers to the rapid, often unseen, fluctuations in light output or color that can cause a visual disturbance. It can occur in lighting systems, screens, or lamps due to inconsistencies in power supply, faulty components, or certain electrical controls. While sometimes imperceptible to the human eye, flicker can lead to visual discomfort, eye strain, or headaches for some individuals. In technology like displays and lighting, minimizing flicker is important for comfort and performance. Overall, flicker is about unwanted, quick changes in light intensity that impact visual experience.
