Kindle screen (monitor) and eyes

In today's changing technology era, we are surrounded by more and more screens This has also led to concerns about whether these screens can cause vision problems such as eye fatigue The main reason for eye tension and fatigue is that they force the eye to constantly adjust the brightness level The eye changes the pupil size by using small muscles to increase or decrease the incoming light This will happen gradually and normally in a day The problem occurs when watching TV or playing computer games, especially in the dark, because the brightness of the TV changes constantly and forces the eye to adjust the brightness level Fast clips of scenes from darkness to illumination can make the problem worse and lead to headaches Of course, TVs and computers need to use light to produce images, but that's the effect of pixels Another problem is dazzling, which is one of the problems we face when we use computers This problem occurs when the screen is placed in front of a window or other light source and is emitted to the screen As the eye moves with glare, it begins to adjust for different levels of brightness When trying to read the words on the bright spot, it means being forced to look at the bright light directly, which leads to eye tension and fatigue To prevent these problems, you need a monitor that doesn't reflect light, and that's why Kindle screens are useful One of the benefits of a Kindle monitor is that it uses electronic ink instead of light to illuminate pixels This ink is arranged where the pixels were originally placed on the screen, and thus the image is generated The advantage of this feature is that it doesn't need any light to illuminate, which means the eye muscles don't have to be adjusted by contracting In addition, the Kindle screen does not have glass, and the materials used are rarely reflective Another advantage is that once the ink is arranged on the screen, no energy is needed to maintain it The screen does not glow, and there is no contrast change when the content changes, because there is no glass reflection All this means that the Kindle screen feels like a normal paper book Of course, no light doesn't mean you can't read in the dark You can use reading lights to light up, just like normal books Other e-readers such as Kobo also use e-ink on the screen, but it will take a while to see computers and other devices using e-ink The reason is related to the different low light background mode used by e-ink screen One of them is the long screen changes, which means there is no way for them to support video or computer games Another reason is that they are only available in black and white, and most people prefer to use color devices.
