The advantages of optical anti-blue light over software anti-blue light are ().

Optical Anti-Blue Light is a hardware-based solution that shifts the peak wavelength of harmful blue light (415nm–455nm) to a safer range at the source (LED backlight).

No color cast (A): Unlike software filters that apply a yellow/orange tint to the screen, optical filtering maintains accurate, natural color reproduction.

Lower harmful light (B): It physically reduces up to 60% of high-energy short-wave blue light while preserving color depth.

Always-on (C): Because it is built into the backlight, it is active 100% of the time without requiring the user to navigate menus or enable "Night Mode" manually.
