jboy, Thank you for your affirmation of our work. We want everyone to be healthy, so we created CareUEyes. It is undeniable that it has some shortcomings, but we are still constantly improving

cue m, Of course, CareUEyes can run under normal user rights

Sal, Did you use a restricted account to log in to the operating system?

Mike, In addition to the effect of light on the eyes, regular rest can also help us relieve eye fatigue

Gero, You already know enough about us, we are honored

No Problem here. Maybe your Firewall blocked Activation?

Meta discussion:

In response to [ giveaways.freebies ], who noted CareUEyes is a 1-year license,

On the one hand, I understand licenses elsewhere, as my driver's license and car registration expire periodically.

My car itself does not expire, though without my license and my car's registration, there's not much I can do with my car, so the analogy falls apart at some point.

I'd be pissed if my car itself expired regardless of my license ( my license, not the car's license ) or my car's registration ( registration to use in public, not registration to exist or use in private or own it or sell it ) - for example, if I had property where I use my car without ever requiring a public license and registration, I'd be pissed if my car arbitrarily expired and I could not drive around my own property any longer.

No analogy is perfect, but this tells me that software licenses come in many forms, and the word "license" is a meaningless term on it's own, especially when vendors throw "trial" into the mix.

"Trial" sometimes means full function, sometimes limited function, almost always limited time.

Since this is a limited-time license, it's equal to a -l-o-n-g- trial.

We GOTD users tend to resent long trials when they appear here merely for profit, as if the vendor is harvesting GOTD users, and sees no other value in GOTD users but potential sales, ignoring the marketing value of goodwill, the value of user feedback, the value of problem identification and resolution, so we feel targeted and used, as we resent that.

We understand
- charging for support,
- charging for updates if needed,
- charging for upgrades if desired.

I will never understand a giveaway that expires, that stops working arbitrarily at a certain time ... because
- at least it creates a feeling of "wasted my time",
- at most it creates a desire to look for alternatives.

Marketing is a challenge; Bill Gates himself was initially upset that programmers freely traded paper-tape programs ( -l-o-n-g- time ago ), telling them to always sell licenses, then Bill Gates himself "gave away" Microsoft Word with every Windows computer, and thereby bankrupted the competition ( Microsoft is a convicted felon of monopoly practices, by the way, for it's attempts to also rig the browser market ).

I have no resolution to the "licensing expiration" problem of what a license means on a giveaway site, other than to remind vendors that expiring licenses are a universal challenge averse to goodwill.

Product review-ish:

That said, it may relate to the product development, or lack of development, itself.

CareUEyes is still in v1, and seems immature regarding features and benefits, unaware of the actual sunrise and sunset and twilight - and moonrise and moonset - where I live, unaware of my timezone, unaware of the many features and benefits offered by the competition.

I'd give full feedback if CareUEyes traded a full giveaway.

FYI, fellow GOTD users,
- I like the feature of making many white backgrounds automatically green,
- I so not like that the green background is random and arbitrary, not on all background, not controllable,
- I'd prefer to have control of the shades of green background, and or any foreground-versus background color,
- I do not like toggling the day and night settings on one set of controls, I'd prefer them to be side by side and clearly identified, and perhaps presented as a single dot on an xy axis instead of two unrelated sliders, I just realized one set of controls toggles between each setting, day or night, by clicking the little circled-arrow on the right that I now see is a sunup/sundown symbol ( not sunrise/sunset, there's a difference not explored by this program ), the description in the title bar SOMETIMES shows what "mode" I or CareUEyes are in, sometimes not, all of this is ambiguous and arbitrary,
- I like the idea of setting the display to an editing mode - invert foreground/background - to possibly eliminate blue flicker headache, but there are no adjustments or indicators,
- I do not like CareUEyes dependence on Aero theme for anything ( so I have no idea what "reading" mode is - it is amberscale/grayscale ? ),
- I like that it seems to not be a "heavy" or a busy program in memory, and I have not experienced system lockups or crashes because or CareUEyes,
- bottom line, aside from the automatic green-replacement-for-white background sometimes in some places, and perhaps the ability to adjust screen color and brightness on demand, CareUEyes has been a passive, non-intrusive, non-engaging program in the background, so to speak, for me.

- - - - - - - - - -

But my concerns here are more for the GOTD community, so I'll suggest alternatives that I have explored ( which today's vendor can check out also, and learn from ):

[ iristech. co ] blue light filter and eye protection to prevent eye strain, optimize screen pulsations by controlling the brightness without PWM pulse-width modulation, reduce eye pain by matching screen brightness to the surrounding light, improve sleep by gradually regulating blue light day and night cycles.

Other folks suggest:
- f.lux
- iBrightmess tray
- ClickMonitorDDC
- Screen bright
- Desktop Lighter
- Dimmer
- Brightness Controller
- Gamma Panel

See also browser extensions:
- Color Enhancer for Chrome ( web search and explore, I love this )
- Eye Protector for Chrome ( also tries to make backgrounds green )
- Advanced Font Settings for Chrome ( makes things easy to read by my own standards )

- - - - - - - - - -

So, c'mon, CareUEyes,
1 - push development beyond v1
2 - reconsider ... trial ... versus giveaway

Thanks for exploring and sharing, folks - GOTD is a treasure.
.

giveaways.freebies, hi .
I see in the description box that the license is for 1 year .
I didn't installed today's offer because I already have installed version 1.1.1.9 ,
from the previous time the program was offered (June 26, 2018) .
That time , the license was lifetime .

Forgot to mention that the program works just fine till today .

Peter Blaise,
you think too much,
go out and be active lol.
