Ink screens are indeed less harmful to the eyes compared to other electronics
Experts say that compared with cell phones, tablet computers and other LCD readers, ink screen is indeed less harmful to the eyes. First of all, cell phones or tablet computers behind the LCD panel of the background light will "penetrate" the screen, with high intensity directly into the human eye, will cause eye irritation and injury. Ink on the screen to irradiate the ambient light refraction to the human eye, the human eye has little impact. Secondly, cell phones, tablet computers use LCD products are issued blue light, which short-wave blue light is harmful to the human eye. Due to the light source, liquid crystal products emit a larger proportion of blue light, can penetrate the normal tissues of the human eye to reach the retina, the retina will cause damage.
However, when reading e-books on ink screens, less short-wave blue light enters the eyes.
Therefore, it is relatively harmless to the eyes. Ink screen e-books with a single color can indeed reduce the fatigue brought about by close eye contact. When different colors of light enter the human eye, multiple imaging focal points are formed. For example, light with shorter wavelengths will be imaged in front of the retina, while light with longer wavelengths will be imaged behind the retina. Cell phone screens are quite colorful, so our eyes need to constantly adjust and adapt when we see these colorful images. However, when we look at a single picture color, such as an e-book with an ink screen, our eyes don't adjust as noticeably and as often.
Eye damage is mainly caused by some bad habits in life
Especially the percentage of myopia among cell phone users, drama chasers and even avid readers is still large. Especially for people who use cell phones or tablet computers more, the radiation ratio of the screen is one of the main causes of myopia. However, due to the times, a great deal of knowledge and information has to be accessed through the internet, which makes it dependent on cell phones and tablets. Then if you want to continue reading while protecting your eyes, you can try e-books with ink screens, which will not harm your eyes and will fulfill your reading needs.
