Blue Shade is a new accessory feature that is designed to reduce blue light on Amazon Fire tablet e-readers when they are being read at time.
Blue light emitted by tablets and other electronic devices is proven to be bad for our sleep. In order to combat this, Amazon Fire tablets equipped with this setting will give users the ability to tweak color settings and read at low brightness levels, making night-time reading comfortable and fun. Most importantly, the feature will make it possible for you to read in bed before drifting off to sleep, without having to worry about the quality of your sleep being compromised.
Amazon Fire's Blue Shade is clearly a visionary accessory, and something that could inspire similar features in other electronic devices going forward.
