You told us you would like to improve your sleep, and that bright light or screen exposure in the final hours before bed is what feels most true for you.
Based on what you told us, this is a practical place to start. Reducing evening light is a low-risk change directed at difficulty initiating sleep and evening alertness. It is not the only approach that may help you, and other factors may also be involved.
Several days.
Notice how long it takes you to fall asleep, and how alert you feel at the time you want to sleep.

Persistent sleep difficulty that affects daily life warrants a healthcare evaluation. If breathing pauses, gasping, or choking during sleep have been observed, or if you have felt so sleepy while driving that you were concerned you might fall asleep, seek professional evaluation.
This assessment provides educational guidance. It is not a medical diagnosis and does not replace evaluation by a licensed healthcare professional. No purchase is required.

What to watch
Your measure is this question: How often do you have difficulty falling asleep when you intend to sleep? Rarely or never · Occasionally · Several nights per week · Most nights · Every night.
Note your answer before you begin, and keep it yourself. We do not keep your earlier answers and nothing you note here is sent to us.
At the end of that time
Ask yourself the same question again. Improvement is a reduction in how often you have difficulty falling asleep when you intend to sleep.
If it has not moved, you can come back to your results and choose a different starting point.
