You are correct that blue-light impacts melatonin.

This brought people to two conclusions which were proven wrong long ago.

1) the drop in melatonin delays sleep onset, or disrupts sleep

2) wearing blue-light blocking glasses prevents this drop in melatonin.

Bright lights decrease melatonin, the decrease is not large enough to have a significant impact on sleep. Therefore, the blocking of blue-light is unnecessary, and it has never been shown to have an impact on melatonin either.
