What is the Afterimage Theory and How Does It Work?
Discover the afterimage theory and the science behind visual persistence and opponent-process theory.
728 views
Afterimages occur when an image continues to appear in your vision after you've stopped looking at the original source. This phenomenon is explained by the theory of retinal persistence and opponent-process theory, which suggests that prolonged exposure to an image exhausts the photoreceptors in your eyes, creating a visual echo.
FAQs & Answers
- What are afterimages? Afterimages are visual sensations that persist after the original image is no longer present.
- What causes afterimages? Afterimages are caused by the exhaustion of photoreceptors in the retina, leading to a lingering visual impression.
- How does the opponent-process theory explain afterimages? The opponent-process theory explains that extended exposure to a color can lead to a compensatory reaction in the opposite color when the image is removed.
- Are afterimages related to optical illusions? Yes, afterimages are a type of visual perception phenomenon that are closely related to optical illusions.
