Does the kindle hurt your eyes, Zhihu?

The first is real eye protection, which you can understand as no different from paper books. . To put it bluntly, it is an object that does not emit light but only reflects light. How can it hurt your eyes? Staring at the unlit wall at home for a day won't hurt your eyes. I used to watch things like pdf on the iPad, not to mention all day, but my eyes were obviously sore after watching it for three hours. I said before that I bought the kindle because I couldn't stand the iPad. In the three days after I bought it, I used ta 10 hours almost every day, and I didn't feel uncomfortable at all. On the contrary, my eyes hurt when I used the computer to find some information, but it didn't hurt when I came back to watch the kindle. Not afraid of not knowing the goods, but afraid of comparing the goods. Although I think it may be easier to have a backlight and read books at night, I think I bought the kindle just to protect my eyes. Why do I hurt my eyes reading in the middle of the night? So I bought 558 (well, to be honest, I have no money (= _ =) hahahahahaha), and then there was a response from someone. I didn't realize there was a reflex at all. To be honest, the light on the kindle screen is not as strong as that in coated paper magazines. How do you usually read magazines to avoid reflections? What do you think of kindle? Let's talk about battery life. The battery life actually makes me feel at ease. Although I did a test last time, it was judged that the total use time of kindle558 should be within 23-27 hours, but charging is really quick. Come on, ....................................................................................................................! If you are not careful, it will be full. Then "dawdle" power consumption. I don't always take out the kindle anyway. In addition, it is rare to read a book for 24 hours and then have no USB socket. A battery life of 25 hours is generally enough. In addition, the compatibility is good, except pdf. Pdf is the bane of almost all small electronic paper books, just like watching the details of Riverside Scene at Qingming Festival on a 6-inch screen (haha, a little exaggerated), but courtiers can't do it. Other than that, everything is fine. I still have concerns before buying, fearing that txt and word are not compatible. Then I found out that I was completely worried. Whether I send it to kindle function or copy it directly to kindle with usb data cable, txt is very smooth. In addition, word uses the Convert function sent to kindle, which is the most convenient and automatically converted into mobi format compatible with kindle. However, I don't have any obstacles in reading pdf magazines with kindle. In fact, I just need to slide gently to enlarge it. Reading pdf books on electronic paper books, don't worry, you must wait patiently. . . It is convenient to read novels and social sciences. All kinds of cloud disks are awesome, especially microdisks and dials. Basically, you can write the name of a book in Baidu search, followed by the word microdisk, and even write it as mobi. This book can basically be read on kindle. Of course, if you have money, it is recommended to buy it at Amazon Mall. After all, it is fast and efficient, and the typesetting is very good. But I have never bought it, mainly because I don't want to buy it. The total number of books in my online disk may be tens of thousands or hundreds of thousands, so I can directly search any book in Baidu Cloud. In addition, there are many learning materials to search online by yourself. You can't buy them. By the way, about the splash screen, this is a little thing that you may not notice if others don't tell you to call it a splash screen. . I didn't get used to kindle in the first minute. Later, I told myself in my heart that if I concentrate on my studies, the terrorists outside will not waver, let alone brush them all at once. I also want to understand the difficulties of those positive and negative particles! ! Later, I revisited Night Walk and never noticed any splash screen again. Because I have finished reading it and I am used to it! What else is there? Oh, I'm sorry to write it as a guide. . Yes, there are purchase channels. I have a good friend who bought KO from Taobao. (to avoid advertising suspicion, you don't have to ask the name of the store in the comments. Some troublemakers in the province say that I write soft articles. ) She told me that it doesn't flash at all and has a long battery life. Although I am envious, I still feel that what suits me is the best (in fact, the budget is not enough). There is really no need to spend 2400 yuan on a reading tool. However, it also reminded me of the name of the store she said. Later, compared with the official 558, I found that their store was cheaper by tens of dollars. Oh, I just bought a shell. However, I was afraid of buying a fake, so I searched his comments and thought it was ok. One is cheap, and the other is that my home is in Shanxi. Ta said I can specify Taiyuan for delivery, but I can't specify the color, because there is only white left in Taiyuan. What I say is white. After all, as long as it is a general express delivery in the province, it is very fast. Plus, I saw a shell and it was not wrong, so I bought it. On the day of arrival, I contacted Amazon customer service and asked her to check the serial number for me. I am relieved that Amazon officially admitted that it is an official genuine product. Although it was a near miss, I still recommend buying it at Amazon official website or Amazon Tmall flagship store. After all, don't worry ... I'm too scared. If it's a fake, I'll waste it. Also, some suggestions before starting, people who really use kindle to read or study. If readers just want to improve their ability with electronic paper books, there is no need to read the following: 1. You have to believe that this thing can do nothing but read books. To put it bluntly, you just spent more than 500 yuan to buy a good ink screen reader. I used its experience browser, which was an explosion, as if I had just returned to the era of touch screen or stylus. The page slides up and down mechanically, and the page cannot be scaled. It's sticky. Perhaps in order to simplify the function or reduce the interference of reading, there is no function of playing MP3, neither earphone jack nor speaker. The only point that came to mind was the microphone, but I didn't expect the indicator light. The reason why electronic screen can't do anything except protect eyes seems to be because of patent 2. Buying a kindle doesn't mean you can save money on paper books, because e-books are getting more and more expensive. By comparing Zhang Peiji's English-translated prose, we can see that the prices of paper books and e-books tend to be the same, and even e-books are more expensive. Especially when the author is still alive and books are popular, the price is even more expensive. If you don't believe me, you can log on to Amazon's web version yourself and compare the prices first. The network disk is a good thing. Stop here and don't discuss genuine piracy. 3. Electronic paper books still lack feelings and accumulation, which may be related to refining words at the expense of typesetting and illustrations. Anyway, I think the fat critic of a dream of red mansions is still willing to buy paper books, a cup of tea, a red chamber and a kind of enjoyment, which is difficult for electronic paper books to do. 4. Electronic paper books are suitable for those who read them once for fun and knowledge, and don't need special marking and learning, not to mention reading copied articles and books repeatedly, such as novels, magazines and newspapers for extensive reading and well-structured rambling. . Intensive reading, taking notes and even doing calculus exercises with kindle are all wishful thinking. Personally, I think buying a kindle or reading various novels is also a sharp weapon to learn English. It is more cost-effective to emphasize extensive reading. After all, I understand that intensive reading needs to draw a picture, summarize the central idea, analyze grammar and create new words. After all, kindle space is limited. Some people may finish intensive reading without drawing anything, that is, they have their own ways. Finally, this is not just a suggestion, but a piece of advice: if you just want to read on a whim, instead of getting into the habit of reading all the time, if you buy a kindle and it's only hot for three minutes, or think you will stick to reading, don't buy it, otherwise it's too late. Because there are books at home, but I can't keep reading them, and then I hope I can read more books after I buy them. It's completely insane. I don't have the habit of reading now. Even if you buy a kindle, you'll eat it in the corner. Hu Shi said it well: those who wait until there is a library to study will not study when there is a library. Anyone who can't do research until there is a laboratory will stop doing research when there is a laboratory. Papi sauce is more practical: intermittent ambition, persistent malaise. I hope everyone who buys a kindle will re-examine their motives. Comment first, I have answered your question. Is it beside the point? I should move this answer a little. The following original answers occupy the pit. Because I use a lot of tablets and laptops every day, and sometimes I use mobile phones, my eyes hurt every day, so I bought a kindle. These days have been miserable. When I get the kindle after the Chinese New Year, I will use it a lot, and I will answer it in a few days. May, 2020.19 update comment area. Someone asked about the splash screen. Flash screen, or there are some individual differences, or my kindle flash screen is slight, or some kindles will flash screen seriously? I can only say that I haven't done statistics, and I dare not jump to conclusions. However, my sharing is to tell you realistically that I personally didn't feel uncomfortable when using the kindle. If you read my sharing, I think the flashing screen will hurt your eyes, which is understandable. You can feel the kindle first and then decide whether to buy it or not. In fact, this is the most suitable method for some doubtful children's shoes. Sometimes, listening to others can't meet your own requirements after all.
