Apple’s IOS 9.3, night mode. Why filter blue light?
Rumour has it, Apple are realizing how important it is to cut out blue light from screens. This has lead to Apple releasing a new ‘night mode’ in their new iOS 9.3 update. This will dim blue light in iPhones and iPads at night. It will do this by changing the blue light it displays, to yellow light, in the evening.
Apple said: “Night Shift uses your iOS device’s clock and geolocation to determine when it’s sunset in your location. Then it automatically shifts the colours in your display to the warmer end of the spectrum, making it easier on your eyes.
Apple has adopted this feature due to the reason that blue light can affect our sleeping patterns and productivity, as previously noticed by Ocushield. Blue light affects our sleeping patterns by suppressing the hormone melatonin. This hormone helps us to sleep each night, and when there isn’t enough melatonin in our body, we stay awake/ruin our sleeping patterns! Therefore, using our devices, throughout the day, and before we sleep, can change the natural rhythm of our body, meaning our productivity can also be affected the following day. Our sleep-wake cycle is essentially disrupted.
The night mode will only be available for users with iOS 9.3, and previous models before the iPhone 5s, will not include this feature. Some older iPad models will also not have this feature included, due to the use of the previous iOS software.
Furthermore, the technique Apple are using to decrease the use of blue light, is by incorporating yellow light instead of blue light, only in the evening. This will give the screen a slight yellow tint in the evening, affecting the display of your screen. Our Ocushield screen protector does not use this yellow tint, maintaining the screen, keeping the clarity of the screen as crisp as possible.
OcuShield uses a blue light screen filter that protects our eyes when we are looking at our digital devices. This is needed as all modern digital devices produce blue light, which can cause eye strain and fatigue, as well as to increase the likelihood of eye diseases. OcuShield protects your eyes and sleep by cutting out the blue light transmittance, but allowing the non-harmful light through the screen to give you clear and normal images.
It is also important to protect your eyes from blue light as much as possible, not just in the evening. Most of us tend to use our phones for a major portion of the day, meaning we have accumulated major exposure to blue light during the day due to the close proximity we hold our devices. This cumulative effect can lead to eye strain, fatigue and headaches. It is important to ensure that we have protection from blue light at these close distances, with our Ocushield, we protect you and your retina.
So make sure, even with the new iOS 9.3 update, we are protecting our eyes from blue light as much as possible, while still being able to retain clear and normal images from our iPhones and iPads. Here is a comparison between an Ocushield filter and the iPhone software.
