Since Amazon released an update to remove the blue light from their devices, many companies are installing it in their software and products. Google and the Moon Reader team have already done so and it seems that Apple is now joining this group.
As we have learned, the new version of iOS, 9.3 brings with it a filter for blue light known as Night Shift, a filter that will allow us to reduce, remove or increase the blue light emitted by the screen.
This Night Shift will be like one more mode that will be available in all 64-bit Apple devices and that have iOS as an operating system, this means that not only new iPads but also iPhones and other gadgets that use that version of iOS but not laptops.
This will be useful so that people can read not only ebooks but anything else on screens with night environments in addition to being able to adapt the blue light to our sight, being the only software that allows this at the moment. Night Shift unlike others allows to regulate the blue light as if it were the brightness or the contrast, something that I consider positive since there are many who have complained about the result of the screen after putting the blue light filter, something that will not happen in Apple products. However, it seems that Apple takes seriously the restriction that exists on its devices in terms of software, thus limiting it even more this function that can be carried by any Apple device and not just 64-bit devices.
Personally I think it is okay for Apple to adapt these new functions quickly, I still remember when the first iPad did not have night mode in iBooks and it was read with light when even Android smartphones had night mode, now it seems that the successor is light blue or Night Shift, but Will all manufacturers do the same as Apple or Amazon? What do you think?
One question I have regarding the famous "blue light." When we talk about blue light, are we just talking about color? Or does it have another scientific implication of wavelengths and such that I don't understand? For example. If I take a light bulb and paint it blue, is that blue light? If I put a blue crystal in front of any light bulb, is that blue light?
Thank you.
