How long before bed should screens stop?

A practical screen cut-off guide based on device distance, brightness and activity.

Read, then test.

The best guide page leads back to one small room experiment.

There is no single cut-off time that fits every screen and every person. A phone held close to the face while scrolling needs a stronger boundary than a dim TV watched passively across the room.

As a practical rule, protect the final thirty to sixty minutes from active, close-range screen use. If work or family life makes that impossible, at least move the most stimulating task earlier and make the room light lower and warmer.

The goal is not purity. It is making the last part of the evening less bright, less close and less interactive.
