Baby and lighting have always been a problem that makes Mom and Dad tangled, especially when it comes to your baby's vision. Which type of light is suspected of causing damage to your baby's eyes. The LED reading light looks beautiful and sounds very high. Is it really the best choice for baby reading?
Does eye fatigue cause myopia?
Before discussing the effects of light on the eye, we must first identify a problem. What we are discussing today is eye fatigue, not myopia. I have been studying myopia for decades, but it is still unclear why people become myopic. The only thing that can be confirmed is that they have found a lot of myopia genes. Although some people study the relationship between myopia and outdoor sports, reading time, etc., the conclusions are: "not sure", "possible", "probably", "estimated". Because the conclusions are unclear, the samples are few, and the research methods are not rigorous, the persuasiveness of these studies is very low. The official calibre of the National Institutes of Health is still: "There is no known effective method for preventing myopia." Regarding the story of myopia, let's talk about it again.
Can the eye fatigue we talked about today lead to myopia? The answer is: there is no obvious causal relationship.
Compared to the dominant factor of genetics, the influence of eye habits is not so obvious. A lot of cautious care around is still highly myopic, or a flashlight in the middle of the night to see the novel is not myopia. In other words, you love or don't care for your eyes, that is, add or subtract a small weight on your genetics, and you can't decide the fundamental fate of your eyes. There is no more care for our eyes in this world than our "four-eyed family". As a result, we are still nearsighted.
Eye fatigue, a problem that cannot be ignored
Of course, we are not saying that you can ignore eye fatigue, even if you do not consider myopia, eye fatigue will lead to dry eyes, soreness, dizziness and a series of follow-up problems and eye diseases. Eye fatigue should be seen as a spontaneous warning of the body, reminding the brain with an uncomfortable feeling: it is time to rest.
It is generally believed that the main cause of eye fatigue in daily life is caused by the long-term tension of the ciliary muscle. That is, if you stare at an object for a long time, it will cause eye fatigue. The intensity of eye fatigue depends mainly on two points: the frequency at which the light source flickers and the intensity of the light. But no matter what the light source, reading a book for a long time or the screen will bring eye fatigue, but it is only a matter of time. It is most important to pay attention to rest eyes.
Eye fatigue is mainly caused by long-term gaze at an object, so the most important thing to pay attention to in daily life is reading light. Don't worry about the question of whether it is not good to chat with your baby in dim light before going to sleep. The Nordic people have not seen their eyes for half a year.
Compared to focusing on reading (book or screen), the eyes are more tolerant of brightness and flicker frequency when looking at moving objects or moving images. For example, a 65Hz CRT monitor can kill you badly, but a 24Hz movie doesn't feel tired for 2-3 hours, because people will use residual vision to connect images. This may be the legendary "brain completion."
The older generation of worms that came from the CRT monitor era still remember that in those years, if the display refresh rate is below 75Hz, it will shake your eyes, it clearly tells us that the reading light source will be comfortable above 75Hz. The flashing frequency of reading in the home is now more complicated. For example, tablets and notebooks depend on the screen backlight frequency (several hundred Hz or more), while reading paper books and electronic ink readers depends on the blinking frequency of ambient light.
LED lights help relieve eye strain, but not artifacts
Daylight is not flashing during the day, no problem. The ambient light frequency in the night is related to the lights you use. The domestic AC frequency is 50Hz, so the fluorescent lamp of your home ceiling lamp and the energy-saving bulb of the lamp are twice as fast as 100 times per second. There is no backlight frequency of the iPad. Therefore, reading a fluorescent lamp, at least in the frequency of light flashing, is actually more likely to cause eye fatigue than the iPad.
If you are using a high-frequency LED bulb , the frequency of the light source can be tens of thousands of times per second, which is helpful for relieving eye fatigue. Although most people don't feel too much difference in their eyes, a study by the University of Essex in 2012 showed that students read better under high-frequency LED lighting than fluorescent lamps.
However, since we haven't started selling LED eye-protection lamps, we will tell you a better choice: an incandescent lamp with an early taste, because the incandescent bulb is a current-heated tungsten filament, so what frequency is used for the fistula? The electricity is that it is not flashing.
But after buying a satisfactory light bulb for a long time, don't forget this: reading brightness has a greater impact on eye fatigue. Choosing your own comfortable brightness and reading under a fluorescent lamp with the right brightness will be much better than an over- or under-dark eye protection. Under the dim bed lights before going to bed at night, the backlit iPad or the Kindle Paper White will be much better than paper or old Kindle. In the high-brightness environment with direct sunlight in the noon, you will see your eyes quickly, which is one of the reasons why drivers are the most protected animals during long-distance self-driving tour.
Scientific use of eye, reduce eye fatigue
To sum up the nonsense, this is the case:
1, reading a book or watching the screen for a long time will be eye fatigue, although not linked with myopia, but it will bring other eye diseases, need to pay attention, the US CDC CDC gives advice 20-20-20, read 20 Minutes, then look at objects 20 feet (7 meters) away for 20 seconds;
2, the light source that people need is different in different situations. For reading, the higher the frequency of the light source, the better, but there is no essential difference;
3, home chandeliers, there is no problem with anything, but reading lights if using incandescent bulbs is better;
4, the appropriate reading light brightness to alleviate the benefits of eye fatigue, far greater than buying an expensive eye-protection lamp but the brightness is too bright or too dark;
5, iPad, mobile phone and Kindle, paper books will be tired of reading for a long time, do not need to be thick and thin, in a dim environment, the iPad with backlight is even better;
6, the light bulb is placed in an angle that people can't directly look at. If you are reading a paper book or a glass screen terminal that is easy to reflect, it is best not to let the light reflect directly into your eyes.
