Somewhat, but with caveats. Blue-light screen protectors (films that stick on your phone or monitor) do filter some blue light from that screen, and many people find them comfortable. But quality varies a lot, cheap ones block very little, and like night mode they only affect the one device, not your room or other screens.
If you want reliable evening protection across everything you look at, amber blue-light glasses are more effective than a single screen film. A protector can be a nice add-on, but check that it actually states how much blue light it blocks.
