Abstract: more and more people will have dry eyes and astringent eyes after staring at the screen for a long time. The American eye Association calls these symptoms computer vision syndrome. Continuing to stare at the small screen will aggravate this symptom. The American eye Association recommends that people rest for 20 seconds every 20 minutes and try to look 20 feet away.
if you pretend to be fighting corns, you will always be fighting corns
fighting corns only appear when your two eyes don’t look in the same direction at the same time. There are six muscles around our eyes, which are controlled by signals in the brain. If your eyes are not aligned, your brain will get two different images. Over time, this will cause more serious vision problems. But you can’t achieve this effect by putting on cockfighting eyes for a short time.
eating carrots can enhance your night vision
in fact, carrots are not bad for your vision. They are rich in nutrients β- Carotene, and then your body turns them into vitamin A, which is essential for vision. But carrots can’t make your night vision abnormal.
the larger your eyes, the better your eyesight.
when humans were born, the diameter of the eyeball was about 16mm, and it will reach 24mm in adulthood. But just because your eyes are bigger doesn’t mean your eyesight is stronger. In fact, excessive growth of human eyes can cause myopia. If the eyeball is too long, the lens of the eye cannot concentrate light in the correct position of the retina, and humans cannot receive clear images.
human eyes dilate their pupils only when they deal with light changes.
are not true. Our emotional and mental state will also cause pupil dilation. Sexual arousal, solving complex mathematical problems and fear will change the pupil size. Human beings do not fully understand the reasons.
ultraviolet rays can damage our eyes only when we are in the sun.
even in cloudy and foggy weather, ultraviolet rays can damage our eyes, which will increase your risk of cataract.
the longer you wear glasses, the deeper your myopia.
wearing glasses with appropriate degrees is the correct solution.
reading in dim light will damage your eyesight
reading in dim light will temporarily overwork your eyes, but it will not permanently damage your eyesight.
poor eyesight will be inherited.
some eye problems will be inherited, but this does not mean that the degree of visual impairment will be the same as that of our parents. Studies have found that if both parents are myopic, the probability of their children’s myopia is 30% to 40%. If only one parent is short-sighted, the probability of children’s myopia is 20% to 25%. If both parents are not myopic, the probability of children’s myopia is 10%.
staring at the screen for too long will damage your eyesight.
more and more people will have dry eyes and astringent eyes after staring at the screen for a long time. The American eye Association calls these symptoms computer vision syndrome. Continuing to stare at the small screen will aggravate this symptom. The American eye Association recommends that people rest for 20 seconds every 20 minutes and try to look 20 feet away.
the correct vitamin cocktail can prevent vision loss.
Harvard researchers do not agree with this statement. Vitamins may slow down the process of macular degeneration, but for people who have nothing wrong, using these vitamins to prevent it has little effect. Perhaps there will be this effective vitamin cocktail bar for the treatment of eye diseases in the future.
dyslexia is related to vision problems.
a recent study by the universities of Bristol and Newcastle found that children with dyslexia are not more likely to suffer from eye diseases than other children.
amblyopia can no longer be cured if it is not treated from an early age.
although doctors say that the earlier the treatment, the better, in fact, with the development of science and technology, there are more and more technologies that can help adults with amblyopia.
what the blind see is only darkness.
only 18% of people with severe visual impairment are permanently blind, and most blind people can distinguish between light and darkness.
human vision on earth is the same as that in space.
although we don’t know the reason, NASA found that space will damage our eyesight.
color blind people can’t see color.
few people can’t see the color at all. The common color blindness is that it is difficult for people to distinguish specific colors, such as red, green, yellow and blue. Although color blindness is more common among men, a small number of women are still disturbed by it.
