The Myriad Visual System – MK. 2 constituted a viewing program employed within the 3PO-series protocol droid line. This instrument empowered the droid to possess sight across a variety of modalities, receiving input from the photoreceptors and interpreting it based on the droid's pre-programmed instructions. The "Human" setting enabled the droid to perceive the world in the same visual wavelengths as Human individuals. Additional settings encompassed a neon function that amplified color vibrancy, and an infrared function that granted the droid the capability of sight in darkness.
