2 days in you won't even notice. you will be amazed at how bright the screen is "normally"

Flux reduces the amount of blue wave length light at night. Blue light is on the lower end of the visual spectrum of engery... close to ultraviolet light. During day time, there's lots of UV light. During night, there's less. The problem is monitors release a lot of blue light, even at night.

The cells of your retina detect these changes in light and relay it to the suprachiasmatic nuclei of your hypothalamus. The visual pathway is kind of wacky, so I won't get into the confusing details... But, when the lower amount of blue light is detected at night, the SCN will release norepinephrine to your pineal gland. The pineal gland will now begin to release melatonin.

Melatonin is pretty much absent in your body during day time. When it is released it does a lot of stuff, such as help induce the onset of sleep. So in a nutshell, this software has little to do with your eyelids and more to do with your sleep hygiene and maintaining proper sleep cycles while using a computer.
