Is the Apple Night Shift Blue Light Filter Really Working the Night Shift?

 

 

 

Have you ever wondered how effective the Apple Night Shift blue light filter really is?

 

We've been wondering the same thing, so we did a little research of our own. Let's find out just how effective Apple Night Shift is in blocking blue light.

 

 

Apple Night Shift vs Blue Light

 The negative effects of blue light on sleep have been well documented. At night, the electronic blue light from your devices switches the brain in daytime mode, which causes the body to suppress its melatonin production, the sleep-inducing hormone that helps us sleep. As a result, our biological clocks are thrown off, which can lead to unhealthy consequences.  

 

When Apple released the Apple Night Shift iOS 9.3, its purpose was to neutralize the blue light from devices, so that users’ sleep patterns would not be thrown off, and their sleep would not be adversely affected.

 

However, a recent research conducted by the Lightning Research Center shows the Night Shift blue light filter fell short of its expectations.

How does the Apple Night Shift Blue Light Filter work?

 To activate the Apple Night Shift feature on your device, the process is pretty simple:

 

  • Access the “Settings” feature on the phone,  
  • Navigate to “Display and Brightness”
  • Turn on the “Night Shift” mode
  • Then, “Shift” the colors from less warm to warmer. The warmer the setting, the less blue light your device will emit resulting in less sleep interference.

 

Sounds plausible. However, when 12 young adults were recruited for a study to test it out, the results were less than promising.

 

The study examined three different settings on the iPad:

 

  • Night Shift disable,
  • Night Shift warmer,
  • Night Shift less warm.

 

Although the Night shift mode did make some difference, the results showed that all three settings suppressed the melatonin production, rather than regulating it. No wonder it was causing such a buzz!

 

 

Why such disappointing results?

 

It’s not the light's color spectrum that affects sleep; it’s its brightness. Although the Night Shift blue light filter was making the screen color warmer, it didn't tone down its intensity, which was precisely the cause of sleep disruption. As a result, the blue light filter was virtually useless in helping users restore their natural sleep patterns.

 

The Apple Night Shift blue light filter is not the only blue light filter out there with questionable results in their effectiveness in blocking blue light. You might have heard of F.lux as well. You can discover more about its effectiveness here.
