In the resting state of ciliary muscle accommodation, parallel rays (light emitted by infinitely distant objects) pass through the refractive system of the eye (cornea, aqueous humor, lens, vitreous), and those focused on the retina are emmetropic eyes, those focused in front of the retina are myopic eyes, and those focused behind the retina are farsighted eyes.
Hyperopia and myopia are blurred vision by forming an enlarged blurred spot on the retina, while astigmatism is the formation of a diffuse halo on the retina. Myopia, farsightedness, and astigmatism are collectively referred to as refractive errors.
When the emmetropic eye looks at a near object, the light emitted by the near object must be divergent, rather than parallel light, at this time, the emmetropic eye does not use the adjustment to focus behind the retina, and forms an enlarged blurred spot on the retina, at this time, the near-reflection triplet movement: pupil constriction, collection, accommodation. When looking at a distant object, the visual axis of the two eyes is parallel, while when looking at a near object, the two eyes have to rotate to the side of the nose so that the visual axis is aligned with the object, which is called a set.
Accommodation refers to the contraction of the cycloceroid muscle of the ciliary muscle, which relaxes the suspensory ligament, so that the lens becomes convex with its inherent elasticity, which strengthens its refractive ability, and makes the divergent light of the near object focus on the retina, forming a clear image. The near-reflex triplet is synchronized (but not all three are always combined or changed to exactly the same degree, but under normal circumstances, they are often linked) and are equal in both eyes. The accommodation used in emmex near vision is called physiological accommodation; Hyperopia will also form a blurry enlarged spot on the retina because of the distant vision, and the adjustment can move the focus to the retina to make the vision clear, while the adjustment used by the farsighted eye is called non-physiological adjustment.
Because the far point of the myopic eye is within a limited distance, because its adjustment range is small, when looking at near objects, its accommodation is smaller than that of the emmetropic eye, because of the synchronicity of collection and adjustment, it is easy to form exophobia; The hyperopia eye has to be adjusted regardless of whether it is far away or near looking, and the adjustment of near vision is to add a part on the basis of the distance adjustment, because of the synchronicity of collection and adjustment, the hyperopia eye is easy to form a seclusion.
It is possible that your child has farsightedness. In general, neonatal hyperopia is physiological. However, if your child has esotropia, it means that the abduction is insufficient and needs to be corrected.
Generally, the pupil dilation examination will be done first, and then the refraction will be done, but if your child is too young, the following subjective refraction may not be possible. The dilated pupil test may take up to a week for the examination and follow-up. It doesn't matter, just listen to the doctor's advice when you get to the hospital, it's fine.

Esotropia Go to the hospital Preschool surgery is recommended 1 and a half years old is too young.
-
Rush to the hospital for a check-up It may be farsightedness.

Help you find it, I hope it helps you!
Yu Gang, director of the ophthalmology department at Beijing Children's Hospital, said that the child's appearance of eyes looking like "eye to eye" has nothing to do with rotating toys. However, the situation of the child's "right eye" should cause parents to pay close attention, and it is best to take the child to the hospital as soon as possible to check whether he really suffers from esotropia (commonly known as "opposite eye").
Yu Gang said that there is also a difference between true and false eyes. Infants and young children often have a flat nasal bridge and are often accompanied by medial canthal folds, that is, half-moon-shaped skinfolds on both sides of the base of the nose, so that the medial eye is less exposed, especially when looking at one side, it looks like the opposite eye. In fact, as long as you pinch the ** on both sides of the bridge of the child's nose with your fingers, the opposite eye will disappear immediately, which is what we usually call pseudoesotropia ("false eye").
Less severe epicanthal folds will improve with age, the bridge of the nose will become higher, and the false eye will disappear naturally. There is a very simple way to help parents judge whether the child is really eye-catching: shine a flashlight horizontally at the root of the child's nose one meter away, and the light points projected on both eyes should be located in the pupil under normal circumstances, if one of the light points deviates from the pupil**, it means that there is horizontal or vertical strabismus, and the child should be taken to the doctor immediately.
Director Yu also reminded parents that if their child is diagnosed by a doctor as having the right eye, they should do so as soon as possible**. Because of the delay in the eyes**, there will be very serious complications, such as severe amblyopia, loss of stereopsis, etc. Therefore, the younger the age of the child's eye, the better, and the methods usually include wearing farsighted glasses, wearing strabismus correction glasses (pressing the prism), surgical correction of strabismus and other methods.

Generally speaking, most babies look to be flattened, that is, the nasal bone is not fully developed, so that it will make the part that looks like there is a white eyeball to cover the eyes, it should be said that this phenomenon to the baby 6 months later, with the development of the nasal bone is complete, the ability to gaze in both eyes is gradually enhanced, and the problem of strabismus can be well improved. If the baby still has strabismus after 6 months, then it is best to ask an ophthalmologist to identify whether the baby has a problem with the right eye.
If it is determined that your baby has a cross-eyed problem, it is best to have surgery as soon as possible**.
If your baby's cross-eyed eye is caused by farsightedness, it can usually be corrected by wearing farsighted glasses.
Correction of physiological cross-eyedness.
Hanging toys at multiple angles is also one of the best ways to help with fake cross-eyed recovery. It is recommended that you can usually place a variety of toys that the baby likes in the baby room, the position should be released as much as possible, remember to make the baby always look at a place, if the baby is just a place to see, it is best to take interesting guidance, and the baby will look at the items in other positions. Especially in the baby's crib, you should place various colors of the baby's color around the baby.
Usually also have to do interactive activities with the baby, such as occasionally holding the baby from the left, occasionally teasing the baby from the right, etc., if the baby's cot can be moved, you can also often move the direction of the baby's bed.
Hold the baby more to participate in outdoor activities, so that the baby can see a lot of different things, usually if the baby is curious about a certain environment, then it will keep driving the eyeballs, and keep turning the eyeballs to enhance the coordination of eye muscles and nerves has a great help, but also one of the best ways to minimize the harm caused by false cross-eyed eyes to the body.

The baby is the heart and liver of the parents, once the baby is found to have any problems, the mothers must be worried, and the mother in the care of the baby when the baby found that the baby has the right eye, so what to do with the one-year-old baby's eyes? In response to this problem, let's learn about it together.
First of all, the eye is also called esotropia, and acupuncture can be used in general, but at the same time as taking the baby, you need to take the baby to dilatation and refraction, and wear glasses to correct the refractive error, which can improve vision. And mothers find that there is something wrong with the baby's eyes, and they must not use eye drops on the baby.
Secondly, generally speaking, as the baby grows up, the eyesight will be enhanced, but the baby is born cross-eyed, so it is necessary to have surgery as soon as possible**. In addition, mothers must pay attention to the baby's eye hygiene, to prevent the baby's eye infection, usually need to take the baby out for a walk, basking in the sun, the baby's eye health is also helpful.
Finally, in fact, for 1-3-year-old babies, mothers do not need to worry about the baby's eyes, because as the baby grows up, the baby's eye problems will be better, but you can't forget the care of the baby's eyes, if the baby's eyes are infected, don't use drugs indiscriminately, it's best to go to the doctor.

This must be abnormal, you can pay attention to it, and then guide it well.

Is the dot normal? Of course it's not normal, you have to go to the hospital to check his eyes.

The method of strabismus varies according to the type of strabismus, and can generally be divided into surgical and non-surgical.
1) Surgery** is to adjust the strength of the external eye muscle and the position of the attachment point by surgical method, so that the eye position tends to be normal. Most congenital esotropia and strabismus require surgery**, and non-accommodative and oblique strabismus usually need to be corrected by surgery.
2) Non-surgical**: Not all strabismus requires surgical absence**, if it is accommodative esotropia, it can be corrected as long as appropriate farsighted glasses or bifocals are worn. If there is also a refractive abnormality of medium to high intensity, it is often necessary to wear glasses to correct it, and axial correction training can be used to help restore monovision and increase the fusion ability of both eyes.
For example, training with a visual axis correction training machine or wearing prism lenses ......Wait. If you do not have amblyopia, amblyopia training is also indispensable**. Volchajang.
0-300 is just mild myopia, it is estimated that it has not affected your normal study and life now, there is no need to worry too much, but you need to pay more attention to yourself and develop a good eye habit. The specific precautions are as follows: >>>More
During the rebellious period of a 12-year-old boy, don't beat and scold, learn to communicate with the child, as long as he is given a time and opportunity to reflect, he will slowly understand and learn to take responsibility. As for studying, you can hint to him slowly, don't be angry with his academic performance or anything like that, you have to pretend not to care, look at his performance, if he also shows that he doesn't care, then you can communicate with him, find a quiet time, sit together and ask him calmly, if he is willing to continue studying, if he says yes, you can ask him. If you don't want to, then you don't need to force him, just let him drop out of school and find a technical school to learn a craft to support himself.
The joints are always rattling, which means that your bones are really not good. >>>More
