Consider the brightness, the timing, and what the screen keeps you doing.
The screen is part of the evening
Bright artificial light late in the evening can interfere with the normal light-dark signals involved in sleep timing. But buying a filter is not the only possible response. NHLBI: your sleep/wake cycle.
Try changing how the device fits into the evening: lower unnecessary brightness, finish an open-ended task earlier, or choose an activity with a natural stopping point. These are practical experiments, not guarantees that a particular screen setting will improve sleep.
Start in the room
Look at the overall lighting, not only your phone. If you prefer a lamp to an overhead light, make it easy to use. Keep safe visibility on stairs and the route to the bathroom.
A useful stopping point
CDC suggests turning off electronic devices at least 30 minutes before bed. Treat this as a practical starting point to try, not a threshold that makes every screen harmless on one side and harmful on the other. CDC: sleep habits.
We do not treat blue-light glasses as an essential purchase. First notice which part of the evening you want to change, then choose the simplest workable adjustment.
