A:Answer Hi Cliff,
Thank you for the question. No, this TV does not have a blue light filter.
With the BRAVIA XR X90K Full Array LED TV, everything you watch becomes more detailed and immersive with true-to-life 4K picture, powered by the Cognitive Processor XR™. With immersive picture and sound, and sleek flush bezel design, be prepared to level up your favorite movies, TV shows, and games. Hope this helps! - Kris
