Interestingly ( perhaps ), in a house fitted entirely with 5600k 96%-daylight spectrum bulbs, I have no problems falling asleep nearly instantly after using a smartphone or laptop.
Perhaps you could try changing the lamp bulbs in you bedroom to daylight-spectrum so there isn't such a sharp distinction between a screen and the ambient light colour?
Could you expand on what prompted you to install those? I had thought the blue light itself was the issue. I don't know what daylight spectrum bulbs are like, but I'm assuming they emit more blue light.
Several years ago I started working from home more, and during the winter found myself really struggling to focus on screens and written text. It seemed to be 'vague' but my eye tests showed no deterioration.
I read online about daylight-spectrum bulbs assisting fine-work ( crafters use them extensively ) and on a hunch I bought a few bulbs. What a transformation! I found myself much more alert and better able to read.
I also like how they seamlessly transition from dusk to pure artificial light, particularly in the rooms we have painted white.
Yep, I recently got a daylight lamp for this very purpose. I point it at my face for 3-4 hours a day, and it improved my concentration a lot. Sometimes (esp. when working on a sleep deficit) the light makes me a bit tired.
Fun fact: When I turn on this lamp it makes me want to tidy up the room, after about 2 minutes. I suspect that's an effect also observed in anti-depressants.
