How can shiny surfaces affect an optical mouse?

Shiny surfaces can interfere with the performance of an optical mouse because they reflect light in unpredictable ways, leading to inaccurate tracking. Optical mice rely on light sensors to detect surface textures, and shiny surfaces may not provide enough contrast for the sensor to function effectively. This can result in erratic cursor movement or the inability to track at all. For optimal performance, optical mice work best on matte or textured surfaces that provide consistent feedback to the sensor.
