A couple of minutes shouldn't affect your sleep pattern. Now, if you were hours looking at the screen before bed then that is another story. This flux effect is more psychological than biological if you were using it just a couple of minutes before bed.

I use my iPad for hours before I go to bed.

It's not merely psychological at all. Response to light is deeply ingrained in our biological makeup. It's the foundation for our biological clock. http://www.marksdailyapple.com/how-light-affects-our-sleep/#axzz2jgmQ1kRF

Actually, just a few instants of light exposure at night will lead to an increased inflammation response: http://www.ncbi.nlm.nih.gov/pubmed/24012645
 
No one forces you to use an iPhone.

It's like suffering from cardiovascular problems and wanting roller coasters to go slower.
 
I wouldn't say it was a medical necessity. If you suffer that badly you shouldn't be looking at screens before you go to bed. Simple as that.

f.lux hasn't even been admitted to the app store as it uses API's that aren't allowed in the app store, simple as. This is not Apple not letting the software in, it's that the software is doing things that are simply not possible via the app store method.
Yes yes, I completely agree. Due to health concerns, people should be punished by not using electronics, because the alternative - opening up an API - would inconvenience Apple more than it would inconvenience the user. Uh huh. Gotta love how Apple is always looking out for the consumer, right?

Human beings have been on the planet for a very very long time now, and we've been looking at computer screens since the late 80's with no problems. flux has been around for a couple of years. It's not a medical necessity.
And screens have changed immensely in the past couple years, from CCLF backlit LCD's to LED backlit LCD's to AMOLED and IGZO. The 20 years prior, you have CRT monitors that could easily be dimmed or color adjusted to whatever you wanted.

Also, it's not even on Android, or Windows mobile.
And explain to me why 2 wrongs make a right? Besides, it's not like Microsoft even supports Windows Mobile anymore, and Android has something similar to F.lux.

Or if this is a medical necessity you could always not use the phone before bedtime. Kind of like if you have diabetes, you should manage your blood sugar.

By your logic, a problem that can easily be solved shouldn't be solved because it would require a policy change? Is policy really that much more important to you than someone's health?

Yeah, rather than having a simple already existing solution be available just fend for yourself. Would we even have cell phones, let alone iPhones if everyone had a view like that?

So you have deepen understanding of this with scientific data to back up all if that for every person that experiences that kind of an issue? And there you go.

LOL. Its called managing your medical condition. People who have heartburn don't eat a bunch of spicy food without taking medication.

Now if Apple adds it that's great, but if using your electronic devices messes up your sleep schedule, don't use them right before you go to bed.

Like I said, a few minutes shouldn't affect. Read my post again ;)

Also since you link to a real paper source (which is a great thing to do btw!), I'm going to give you another one which has to do more w/ actually sleeping:

Dim light at night does not disrupt timing or quality of sleep in mice.

Aren't scientists cool w/ rat theories & experiments ;)

Probably more than you, especially scientific medical understanding of it. ;) (see my bio I guess)

Ah, so people who experience heartburn don't just not eat spicy food they take medication that someone makes and that helps them with their condition. Nice way to provide a counter example right in the argument.

Yes, they take medication. If there is no medication, they shouldn't eat spicy food and then complain about the results.

It there is no screen temp control, don't use your gadget right before you go to bed and then complain that your sleep is messed up.

But by all means petition Apple to include that feature.
 
ITT: people ridicule OP to try and justify the closed nature of iOS.

I think either you'll have to move to an open OS (Android), or wait for Apple to maybe announce it as a 'magical and revolutionary feature in iOS 8'.

So you actually understood that post was asking about knowing for sure how something like this applies to everyone who experiences and being able to speak for everyone who does, right? And there you go. ;)

People just love pointlessly putting down others, especially anonymously online.

But if there's no medication shouldn't those people discuss that and being that up so that a medication (especially one that's already in existence) would become available? The "analogy" in the argument only furthers that point it would seem.
 
I can't believe so many people are ridiculing the OP and saying 'just don't use your phone'. You know nothing of his lifestyle and/or his condition. Saying these things is incredibly ignorant and facetious; we live in the 21st century and the technology exists to allow him to live exactly as every other person does, and the only reason it isn't on the iPhone is because of Apple's rules. Nothing more. Just rules.

Show some empathy.

I think had the OP started with stating that wanting f.lux approved was a desire and not a NECESSITY (and lose the upper-case), they probably would have elicited more empathy.

I took a few Neuroscience courses, I can confirm this to be true, although I cannot confirm what I was taught came from a different source than the NIH study quoted in this thread.

Thanks for your reply. It seems trolls just jump on this thread just to ridicule and try to invalidate the problem.

As someone who suffered majorly when LCD screens switched from CCFL to LED, I completely understand how much a slight eye strain can impact daily life - to say nothing of something more serious. And to think that it's something as simple as an API change - hardly what I would call an engineering or mechanical issue as CCFL -> LED is - and people are complaining so much is just infuriating.
 
LOVE f.lux.

Had it installed on my iDevices when they were jailbroken.

Same here. That was my favourite jailbreak tweak. However, I have grown accustomed to putting brightness at the lowest level and activating inverted colours whenever I am in dim or zero light.
 
I don't consider f.lux a medical NECESSITY,

YOU don't. WE do.

----------

BTW, guys, it's also worth mentioning Android has this almost out of the box, available right in the Google Play - that is, you don't even need to root your device to use the similar apps.

I've been using "EasyEyez" and / or "Good Sleep" (both free) on my stock, non-rooted N7 2013 and they've been GREAT. I assume they'd work similarly well on any other Android device.

Again: you do NOT need to even root to do this on Android. While on iOS... well, I don't even go on...

Exactly. It's sometimes really amusing how far some Apple fanboys go when they defend the very stupid decisions / rules of their beloved company.
 
Yeah, although TVs aren't really the same, as the screen is much further away from your face.

Actually, color CRT's are of much better and even spectra, meaning the light you receive from a CRT doesn't have excessive blue components. This is the spectrum of a standard color CRT:

CRT_phosphors.png


Note that the blue area hasn't higher intensity than the green / red one.

And this is that of a standard white LED (these LED's are used in almost all LED-lit LCD's):

White_LED.png


See the HUGE peak at around 460 nm, that is, blue? THIS is why all these backlights are blueish.

Unfortunately, white LED's just can't produce as even spectrum as CRT's (see first image above) or the substantially more expensive (and, therefore, very rarely used) RGB LED backlights:

Red-YellowGreen-Blue_LED_spectra.png


(Images from the Wiki: http://en.wikipedia.org/wiki/Light-emitting_diode and http://en.wikipedia.org/wiki/Cathode_ray_tube )

All in all, this is why watching CRT TV's don't pose any insomnia danger - your eyes receive way less blue light than from a white LED-backlit TFT screen like that of iDevices. The two screen technologies just can't be compared in this respect - LED is way worse.

Unfortunately my personal experience contradicts your science. I avoid any blue light at night. I try to avoid most light at night!

1. Use plain red LED's for illumination at night. It'll surely won't cause insomnia but you'll still be able to move around even at night.

I've chosen red LED bulbs after careful examination so than I can be sure they don't flicker at twice the line frequency. (All my home lights are high-quality, expensive, high-CR LED's with no flicker and an absolutely beautiful light.)

2. Nevertheless, what I've written about CRT's vs. white LED backlit LCD's is right - it's the huge blue peak in the spectrum of these kinds of LCD's that causes the most problems, even compared to CRT's.
