BTW Iris Mini removed f.lux from my computer the second it installed, before I had a chance to exit the program. If I had known it was going to do that, I would not have installed it. That is NOT OK for an application to remove another one without my consent. And I tried Iris Mini when it was given away last year, but didn't like it as well as flux. I decided to try it again today in hopes it was improved. Now I'm ready to remove it from my computer, thanks to its rude behavior.

I almost forgot about this program, but luckily was able to D/L and install it about 20 mins. before the end of the giveaway. However, there is no menu item for "Activate Pro" so I can't enter the registration key. What gives?

Thank you very much!

Right clicked to register and did not see option offered. What am I overlooking? I even tried "register" in hidden features.

dl & run the s/w, but Panda G Protection block it.
disable Panda, and click setup.exe again.
no problem all the way, successful running on my system.
as my nb's screen has no protection screen on,
i think i can save $$$ on using this s/w to protect my eyes.
so thanks GOTD & IrisTech.

Stupid question...I have " Iris 0.9.0.4 " installed (No Pro mentioned) installed from another giveaway....Is this version better ??

I am confused. The version I have already installed is 0.9.x.x while this version is 0.3.7.3. 0.9 is usually NEWER than 0.3?????????

Painless installation and registration on my Win7 Pro x64. I think this will be very useful for me, especially in the evening as I approach bedtime. Thanks very much, GAOTD and Iris Tech!

Interesting software. Just installed to my Win 7 x32.
Let's see how it helps my eyes.

I can attest to the general benefit of reduced blue light emission as well as reduced flickering because they definitely reduce eye strain. Your eyes can feel the difference the longer you're viewing the monitor. Won't need this for my newest monitor which has the "low blue light" thing plus it's a 100Hz G-Sync curved screen model. Years ago I lived in England where the frequency of the AC electrical supply is 50Hz (compared to the USA where it's 60 Hz). Unfortunately, I could always see the TV flickering and even some lights flickering in my peripheral vision. This leads me to believe that the higher the refresh rate of your monitor, the better.

That's a great idea for a software. I've started to suffer from photophobia (sensitivity to light and brightness) and the screen does not always reduce enough and that can give me migraines at times...
Good software. Thanks GOTD and Iris Mini Pro's team.

When I tried to run the program I received the error message "Windows cannot open this program because it has been prevented by a software restriction policy".
My guess is that this policy has been implemented by Cryptoprevent, which I am using to safeguard my system from ransomware. As far as I know, it is not easy to disable, and in view of today's news concerning the worldwide epidemic of encryption viruses perhaps I shouldn't try, so testing Iris Mini Pro will have to put on hold for the time being.

I just installed this on Windows XP SP 3 x86 and it works great. I had to try even though it says this program is for Vista or later.
Just thought I'd let you all know in case you're still using Windows XP.

Btw, windows 10 already has a night mode feature (since the recent creator's update). Just google it.

Tried out the previous version when it was given away here a few months ago. It was negatively affecting my online gaming as it caused some high CPU use every few seconds and this lead to temporary short hangs in the game...

Not meaning to carry wholesale judgement on the product, but when I installed it, it immediately changed my mostly white screen into a darkish orange. The first thing you try to do, then, is find a menu, a command, something, to undo the unwanted change, before you even begin to examine the program. Alas, there's none available.

I mean : no obvious command, such as "undo", "normal", "default settings", "adjust colour", "bring back an honest-to-God white screen, you moron" -- you get my drift. Only some cryptic things like "automatic". I don't remember what I did to kick out that stupid orange glow. Probably exited the program. Then I think my screen reverted back to normal -- however it might have become bluer than before, I don't know. I'm sure there was no message such as "Iris restored your previous settings" -- an obvious requirement.

A bit later, I tried to determine whether the program was installed or portable. It turns out it "installs" itself... no questions asked... in the AppData folder ! And not even in my own AppData : I follow the recommended security practice of using a non-administrative Windows account all the time, but software installing themselves obviously ask for administrator privileges. So this program stupidly thought my user account was the administrative account, which I almost never use.

Developers of such programs needs to understand one thing : they should live by the doctors' most sacred obligation : above all, do no harm. Maybe your software is the best thing since sliced bread, and maybe it will change people's lives. Maybe. However, you need to be humble and take care not to disrupt your users' workflow and habits. Realise people out there have spent long hours calibrating their screens to an acceptable setting. Don't begin by breaking everything just to get noticed. If, by accident, you do, give people an easy way out.

Generally, be discreet. I'm sorry to break the news to you, but even if your screen-adjusting program is absolutely terrific, it will be used 1 per thousand of the time. So your first duty is to get the hell out of the way. And provide obvious, user-friendly commands for the rare instance when your product will be needed.

One strong point of this program is its detailed online user manual. You can see, there, that the developer sincerely thinks that at 3 pm your whites should be a dull pink, and that by 10 pm all you should be permitted, instead of white, is that disgusting brownish orange I was talking about. I suppose this is adjustable by the user, but if the first thing a program does is stupid choices you need to manually correct, that's moderately encouraging. Hint : adjusting screen colour temperature is about nuance. Slight changes. Almost imperceptible settings. It's not about pouring a pot of paint over the screen.

I uninstalled Iris, because it gave me such a bad start that I really don't have the motivation to investigate whether something better lurks deep inside.

I don't use a regular computer monitor for my desktop or the screen on my laptop. I attach both to big screen tvs via HDMI and use them as my 'monitors'. So, does this apply to me?

Thank you GOTD Team and Daniel Georgiev for this offering today, I will give it a try.

@MikeR,

I'm not really sure what you meant by "Almighty Apple has -- disgracefully -- flatly refused to do." But Apple does has Night Shift for Mac https://support.apple.com/en-us/HT207513 and for iPhone, iPad and iPod touch https://support.apple.com/en-us/HT207570

In terms of this specific version of Iris vs f.lux, f.lux may indeed be the preferred choice, but while it is not free, the Iris Pro version appears to have far more control over settings. I have not yet purchased Iris Pro - 10$ - but will do so soon. In the meantime, I would recommend picking this one up today while it is free. It does work well, and easier to use than the built-in settings available with Windows 10.

A very important setting for me is the ability to set different monitors for different settings. This is reported to already be a part of the current version of Iris Pro (see full lit of settings and options in link below) and also something the current beta version of f.lux begins to address. I could not get the beta version to install and function properly on my system, only the current stable version, so I cannot determine to what extent such a feature does or does not work in the way I hope it does/will.

For a well done review of both Iris and f.lux, see....

And for a list of all Iris Pro features, please see....

P.S. to the Iris developer, would you consider a one time discount offer for the full Pro version of Iris? Thanks.

I see the icon in the taskbar notification area. I find no way to display the "Pages" referred to in the manual.
Color changes when I left click the icon.
Right clicking shows a pop up for modes with "Exit" at the bottom.
I see no way to get a main menu function.

Help please.

I'm just wondering, if this is still useful for monitors today that are not CRT-based?

Great little app! Got it and the Iris Pro recently from another source. Its big sister Iris Pro has more bells and whistles, but for my laptop, the Mini is fine.
Thanks, Daniel & GAOTD!

My monitor has buttons for Normal, cool and warm pre-adjustments.
I just push the warm button at night and in an instance the background become pinkish and the blue colors are subdued.
Also most video driver software allow for custom color settings and adjustments to be preset.
If anyone talks about frequency adjustments is pulling your leg.
You can not force 60Hrz monitor to work at 30 or120Hrz, you will shorten the life of the monitor or burn it very easy.

Hi. Tried to be a good user and read the friendly readme file. Right clicked to register and did not see option offered. What am I overlooking? I even tried "register" in hidden features. Need more coffee?!?

I have been using Iris Mini for the past year, since a previous giveaway, and am mostly pleased with its utility.

However, be warned! As it quietly does its job in the background, as I soon discovered, it is an appalling memory hog. Think of Dear Henry's bucket.
It quickly climbs from under 10 Mb working set memory up the process list until it's sitting somewhere just under memory-intensive processes such at multi-tab browsers and readers, somewhere around 200-300 Mb working set.

This hasn't prevented me from using it, but necessitates a fairly frequent visit to a process explorer and several restarts a day. The leaking memory is obviously a flaw, and I have written to the developer, Daniel Georgiev, but have never had a reply.

I believe I might like this....
It's a bit weird at first.

It supports 3 high res monitors. I like that (some products do not).

As "Sheldon" might say, "What are we now, a bunch of hippies ?" (LOL)
This program has a sorta new age, odd feel that seems to require a bit of getting used to. Not a bad thing, just somewhat different.

It's possible it might be the next best thing to sliced bread. Time will tell.
Oh well, we're all part of a great "Science Experiment" so what the heck.

Personally, I would suggest you install it.
There's something intriguing about it. : )
Installs well (W7-64).

Fortunately for Laptop and LCD LED screens do not flicker but this software will help with color contrasts.

I've been using f.lux for years and love it. I would have guessed that the eye needs more light at night. Not so according to studies. Downloaded on Win 7 Home Pro 64 bit. Set my time zone, and that's that. The other brightness features are very nice too. Thanks, GOTD.

Installed without a problem on Win 8.1. Enjoying the rest for my eyes. Thank you for posting.

This is great for me. It's easy on my 59 year old eyes. Thank you.

That's what I like to see: software so cheap that if you miss the free window you can still afford to buy it!

Thank You Daniel Georgiev and GOTD
Downloaded and installed without the normal troubles.
Installed on a Windows 10 Pro Creator Update PC 64bit. - No problems.
As another commenter said in the latest build of Windows 10 we have this sort of implemented already, but it requires location services to be active and only adjusts your display when it detects sunset or sunrise. With this program I can now remove the blue light from my display all the time or any time I want.
Useful software for once

thx again. Sharing is caring.

Following on from tk's post, I'm obviously not alone in being a bit, well, baffled by the developer's claim to have come up with a software control of a hardware functionality.

I've used the donationware f.lux ever since US ophthalmology researchers Lorna and Mike Herf released it several years ago:

https://justgetflux.com/

On which basis then, many thanks to today's developer Daniel Georgiev and GOTD for bringing to the attention of many the issue of eye-strain and, crucially, the effect of different wavelengths of light on mood and sleep patterns.

PS: special kudos to Daniel for generously acknowledging f:lux in his product description, something which the Almighty Apple has -- disgracefully -- flatly refused to do. But then, a mere husband-and-wife team like the Herfs have no chance when the fruity monolith claims its much-touted 'NightShift' is all its own work. . .

https://justgetflux.com/ - free and probably better.

f.lux is free and does the same thing.

Isn't this the same as the new feature in WIndows 10 Creator update known as "Night Light"? Making this program somewhat redundant for newer systems.
