"Makes my eyes much less tired!"
It gives the screen a nice hue which doesn't just fade it but makes it look softer in appearance. It's customizable too so if you want to work for a long time during the day, you can set it to reflect the night time vision. The hues/saturation can be adjusted to suit you too.
It takes a bit of time to get used to it!
It was strange getting used to it but it is such a good little program that it is worth the 'adjusting' time. It's no good to use it while photo editing. You can disable it and change the settings as you wish.I forgot to mention - it works with Windows 8.
Cnet should definitely give a review on this and make it obviously available to everyone.
