What do baby eyes do What do baby eyes do?

Green eyes are people from France, Germany, England and other European countries, and the so-called blonde and blue eyes come from this.

The eyes of French, German, and British people are green because people in European countries have less iris pigment in their eyes, so their eye color is pale green. The color of the eye refers to the color of the middle part of the eyeball that is covered by the iris. The iris contains many pigment cells, and the amount of melanin in the pigment cells determines the shadow of the iris.

The darker the color of the eyes, the less pigment they have, and the lighter the color of the eyes, <>

Principle of iris discoloration of the eye:

The iris has smooth muscles arranged around the pupil, called the pupil constriction muscle (pupillary sphincter), and smooth muscles arranged radially around the pupil, called the mydriatic muscle (pupil opening muscle). The former is innervated by parasympathetic and the latter by sympathetic.

When bright light shines on the eye, the pupillary sphincter contractes, restricting light entry; When light is weak, the pupil dilated by the pupil dilated by the dilated pupil and increased light entry. The size of a normal pupil is also related to many factors such as age, refractive status, etc.

Infants up to 1 year of age have the smallest pupils, which gradually increase and become smaller after puberty. The pupil of the myopic eye is larger than that of the farsighted eye. When people are in pain or frightened, their pupils dilate, and when they sleep, their pupils are dilated.

The baby's eyes are still very useful for side drying.

But in short, Yun Hongdong can be summed up in a word, which can be said to be similar to the role of your eyes.

What your eyes do, so do your baby's eyes.

Light and tears

Newborn babies respond to light, and if they don't feel light or darkness, it means that they are not normal. If your baby is born with watery eyes and frequent symptoms of eye droppings, discharge, or inflammation of an infection, he or she may have congenital nasolacrimal duct blockage.

Eyeballs

The baby's eyes can be fixed at 2 months old, and the baby's eyes can be observed for tremor at this time. If your baby's eyes can't fix their gaze and they keep drifting (either binocular or monocular), their vision isn't very good. In addition, you can take a brightly colored toy ball to observe, after attracting the baby's attention, and then slowly move the ball to see if the baby's eyes can move with the ball.

Cornea

The average size of your baby's cornea (the part of the black eye) is that if the black eye is too large (more than 12 mm within 1 year of age) and there are symptoms of photophobia, tears, or even corneal opacity (whitening of the black eyeball), there may be symptoms of congenital glaucoma.

Pupils

Take a small flashlight and take turns shining it on your baby's eyes to see if the pupils will constrict, whether the reaction of the eyes is symmetrical, and whether there are white pupils. A normal pupil should be black and turn red or yellow-orange due to light reflections when exposed to light or photography in a dark place. If you find a white pupil, you should see a doctor as soon as possible to confirm the presence of eye diseases such as congenital cataracts or retinoblastoma.

Blindfold games

How it works. First take a toy to attract the baby's gaze (fixed vision), cover one eye when he is not paying attention, and the normal baby will feel that things become three-dimensional (only three-dimensional is three-dimensional when looking with both eyes). Cover one eye at a time, and switch to the other eye the next time you play.

Observe the focus. 1.Can my baby play with one eye continuously? If it can, it means that the vision of this eye is not too bad.

2.Does your baby feel when you cover one eye? If you don't feel it at all, then it may be that you are playing too attentively, or it may be that the eyes that are covered have poor vision, and it doesn't matter if you cover it or not, and the baby can hardly feel it.

3.At the moment when covering one of your baby's eyes, observe whether the other eye has moved. If there is, there may be strabismus.

4.If your baby's left eye is always covered but not his right eye at all, there may be a problem with his left eyesight. If this is the result every time you play, check your left eye as soon as possible. This article**:

When children are born, the eyeballs are generally relatively small, the anteroposterior diameter is very short, most of them are farsighted, and the vision development is incomplete. As we age, our eyes gradually become longer, the degree of farsightedness slowly decreases, and our visual acuity gradually increases. Under normal circumstances, at 3 months of birth, the visual acuity is, and the visual acuity at 6 months is the visual acuity of children within the age of l, so the farsightedness of children within the age of l is relatively poor, and the visual acuity increases at the age of l, and the vision reaches normal at the age of 5, and the eyeball of the 12-year-old child is fully mature.

If there is no problem with the child's eyes, myopia is generally less likely to occur during this period. However, due to abnormal eye development or myopia genetic factors, it can affect your child's vision during this period, so checking your eyesight as early as possible is the best way to detect your child's myopia in time.

To check the child's eyesight, you should be patient, have a kind attitude, give more praise and encouragement, and strive for the child's cooperation, so that the results can be accurate.

In addition, parents should also carefully observe their children's every move in their daily life, such as finding that their children are slower, clumsy, inactive, and unwilling to play games than other children of the same age; or tilt your head, frown, squint when you look at things, sit close to each other while watching TV, and often rub your eyes with your hands; Difficulty concentrating in class after school, not being able to see the blackboard clearly, declining academic performance, or reading books in close proximity; If you have eye soreness, pain, dizziness and other symptoms of visual fatigue in less than half an hour of reading, you should take your child to the hospital for examination, and if necessary, dilated eyes for refraction.

In short, parents must carefully observe their children, especially young children with a genetic predisposition to myopia, and cooperate with kindergartens and schools to check their eyesight regularly in order to detect their children's myopia early.

Finally, it is emphasized that the most effective and convenient way to find myopia is to check the eyesight regularly, generally once every 3-6 months, but to confirm the myopia eye, it must be refraction.
