Here's an article that suggests blue light doesn’t really affect your sleep, but as someone who has f.lux installed and finds that it does make a difference, I am skeptical of such claims.
…scientists have connected in many, many studies not just light and melatonin suppression, but specifically light that’s heavy on blue frequencies. Blue light can ostensibly offset the cycle of hormone production by a couple of hours or more. This has led to speculation that staring at television sets, monitors, and mobile displays disrupts or delays sleep. If you have to get up or are woken up at a fixed time, as for most people, this both reduces sleep and throws off the body’s endocrine and other systems.
