Apps / Software :: Automatic Setting Adjusting Light Based On Time

I found that f.lux is really useful to your eye when you look pc all day.

However, I found that the light setting doesn't gradually change according to time.

For example, at noon the setting is at the highest peak. So there is different light setting across the day time.

It would be good for night if there is automatic setting for light gradually set to the lowest at midnight.

When this happen, the word and picture look totally different and the nothing come out from the blue colour. I might as well go to sleep and continue work tomorrow.

Is there a way to set a few setting and when the time come, f.lux change the light setting? It may not be fully gradually change but at less there is different in the light setting than have it all same all day.
