Look at this spectrum:
These LED smart light emit color by mixing Red, Green, and Blue (RGB) lights
If the only visible color is Red then, no, it doesnβt emit blue light
But if you select a color like yellow, for example, there will be an emit of blue light
The same goes for your monitor, it constantly emits blue light and has PWM flicker which is really harmful to your eyes
If you want to remove the blue light and flicker, you can try Iris, which is a program made exactly for that
