Today, the topic of health jun and everyone is "vision", let's do some interesting tests first
Is your vision normal?
01
Keep the picture below a certain distance from yourself, and remember to take off your glasses to see:
Who are you seeing in the picture?
Here's the answer
↓
1. People without myopia see Einstein.
2. Myopic people see Marilyn Monroe.
02 Next, let's take a look at the following diagram:
Can the lines in the figure be seen clearly?
1. If the thickness of the lines in all directions of the astigmatism table is uniform, it indicates that there is no astigmatism.
2. If a line in the astigmatism table is found to be black and clear, it indicates that there is a possibility of astigmatism.
After the quiz is done, what are the results of everyone? Health Jun believes that whether your eyes are currently nearsighted, astigmatized, or still healthy, you should protect them from harm in the future.
About "Doing This Hurts the Eye"
Wrong statement
Does watching TV for a long time, using a tablet, playing a computer, and playing mobile games really break your eyes?
I believe that everyone's first reaction is: surely!
With the improvement of living standards, now there are more and more interesting things to play, and children in every household are basically a bit "inseparable" from electronic products, and even use mobile phones, tablets, computers to learn in class...
As a result, everyone will worry that "children will break their eyes after playing these for a long time."
The correct answer is: No!
Experts say that reading books, watching TV, playing mobile phones, etc. for a long time will not bring permanent physiological damage to the eyes. Doing so only causes eye strain, with fewer blinks due to high concentration.
Use eye Tips
Watching TV for a long time, playing mobile phones, etc. is not a problem, the key is to reasonably arrange eye rest and alleviate eye fatigue. Health Jun recommends resting for at least 20 seconds every 20 minutes, looking away 5 meters away.
02 When watching computers, TV, mobile phones, can getting very close to them break my eyes?
I believe that everyone's first reaction is also: it will be!
At this time, did everyone faintly hear the words of the mother and father again, "Sit far away and watch!" Do you still want your eyes?" ... Over time, we will often say to children, "Don't get so close, it's not good for your eyes!"
Whether watching TV or reading a book, being close does not cause physiological harm to the eyes.
The eyes of children are different from those of adults, they will make their eyes in a more comfortable state when they look at things nearby, and looking away from a distance will make children's eyes feel uncomfortable. This phenomenon generally decreases gradually with age.
Find a balance point and let the eyes see things in a more comfortable position.
When looking at a computer, the recommended distance from the screen is an arm's length, slightly overhead angle.
When watching TV, the appropriate distance is about "screen diagonal length x 1.6".
These are relative to adults, children may be slightly closer, so parents should accompany their children to watch, observe and inquire, and help children find a viewing distance that is comfortable for the eyes.
03 Mild myopia with glasses will quickly add depth?
Many people are often misled by the question that "wearing glasses will deepen the degree", and even when I was a child, I had this experience of "some slight myopia, afraid of deepening myopia and not wearing glasses."
The correct answer is: No! Even if the spectacle power is not appropriate, it will not be!
Myopia is the same as height, it will stop at a certain age, and wearing or not wearing glasses will not cause myopia. Wearing glasses with inappropriate degrees will only speed up eye fatigue, resulting in various eye discomfort problems.
Wearing glasses is mainly to control the development process of myopia, as long as they are worn properly, they can greatly reduce the annual growth of myopia, which is a very important help for myopic people.
In general, if the visual acuity of the naked eye can be more than 0.6 during refraction, and the difference in vision in one eye is less than two lines, then you can usually wear glasses when reading books and watching TV.
On the contrary, it is necessary to wear glasses for a long time.
"It doesn't hurt your eyes to look at it for a long time, it doesn't hurt your eyes to see closely, and you don't hurt your eyes when you wear the wrong glasses." So the question is, how do our eyes get hurt?
