More correctly,
some members of the human species seem to be affected by blue light. From the summary quoted below, there seems to be no agreement in the studies that investigated potential ill effects from blue light exposure within 1-3 hours of attempting to go to sleep. The summary gives a rather strange mix of conclusions and does not make it clear whether some of the studies found their conclusions based on a reduction in exposure to blue light. Does the decrease in sleep quality, duration efficacy and sleep latency indicate a reduction in blue light caused those issues or exposure to blue light close to trying to sleep. Looking at some of the studies that did not require an academic login was an exercise in curing insomnia.

Summarizing the influence of blue light exposure, the following results were found (expressed as proportion to the number of studies investigating the particular parameter): Fifty percent of studies found tiredness to be decreased. One fifth of studies found sleep quality to be decreased and one third found sleep duration to be decreased. Half of the studies found sleep efficacy to be decreased and slightly less than half found sleep latency to be increased. More than one half of the studies found cognitive performance to be increased. Slightly more than two thirds found alertness to be increased and reaction time to be decreased. Slightly less than half of the studies found wellbeing to be increased.
