How do you know if you are nearsighted, and how can you know if you are nearsighted

You say that looking at the blackboard is blurry, and after a while it comes back to because your eyes are adjusting the focus

Our eyes can focus manually, but if we are nearsighted, it seems that this advanced function is degraded

More than 100 degrees does not seem to be a very serious myopia, it is estimated that it is false, and it is good to take care of your eyes

In addition, you say that you will cry when you look at the bright lights and come into contact with the smell of smoke, which proves that your eyes are very tired, and if you rest your eyes as soon as possible, your myopia will be even higher!

This brother, your eyes are pseudomyopia, sometimes good and sometimes bad, if your eyes are tired, you can't see clearly, if your eyes are well-rested, you can see clearly

In addition, if it is a distant view, or a clear and soft view, it is generally good for the eyes So if you don't plan to **, you can try to travel Maybe it's good to come back from the trip

In the relaxed state of accommodation, parallel light rays are refracted by the refractive system of the eye and converge in front of the retina. Among them, axial myopia is more than -6d is called high myopia, and those with various degenerative and degenerative changes in the fundus of high myopia are called pathological myopia, and the axial elongation and thinning of the eyeball wall, especially the posterior sclera, are the basis for axial myopia to develop into high myopia.

You can go to the hospital to have your vision checked and refraction to determine if you are nearsighted.

There are several symptoms of myopia, and if you notice symptoms such as blurred vision in the distance and squinting when looking at things, you may be nearsighted.

Manifestations of myopia:

1. Squint. When distant targets cannot be seen clearly, squinting is often used to compensate, because the eyelids can block part of the pupil when squinting, reducing diffuse light and reducing the impact of astigmatism, thereby temporarily increasing and improving visual acuity.

2. Blink. Frequent blinking can be programmed to alleviate myopia and increase visual clarity. Many people will see things more clearly when they are in tears.

3. Tilt your head. It often happens that tilting the head to watch TV, also because when tilting the head, it can reduce the interference and influence of some diffuse light, and some children will even develop the habit of tilting their head.

4. Error. The target in the distance is not clear, and I don't say hello when I see acquaintances. I make mistakes during exams, I can trip over or hurt myself when I move in the dark, and some of them have a decline in academic performance, and I often have to borrow other people's notes to copy, etc.

5 early symptoms of myopia:

1. I like to squint at things.

2. Look too close.

3. Frequent blinking.

4. Rub your eyes often.

5. Frowning often.

You can test yourself, if you are tired of seeing things closely, it means that your eyes are myopia, if you see things, you can see very clearly above five meters, it means that your eyes are very normal.

You should be on the verge of pseudomyopia, pay attention to the time you use your eyes, relieve eye fatigue, and go to the place where you sell glasses to test it when you have time.

If you use your eyes too much, your eyes will be easy to get tired after doing the questions for a long time, and you will not be able to see clearly, and you will be much better when you sleep well. If you want to know the prescription, you can go to optometry.

If you have time to find an eye hospital or an optical store, ask him to check it for you or check your eyesight yourself, and then use a computer refractor to make an eye strip to see, which is very simple and takes less than two minutes.

If you look at the distance and appear black or blurry white, you can determine that it is myopia. You can also go to the place where you have glasses, and the test is usually free. Useful words. Thank you!

Prone to visual fatigue when looking at things is a sign of myopia.
