optical tracing

Optical tracing is a process used in optics and vision science to study how light rays travel through lenses, glasses, or optical systems. By mapping the path of individual light rays as they pass through these systems, scientists can analyze how they focus, bend, or distort images. This helps in designing better lenses, correcting vision problems, or understanding how optical devices work. Essentially, optical tracing visually illustrates how light interacts with different materials and shapes, allowing for precise assessment and improvement of optical performance.
