How many months can my child have his vision checked? Your child s vision can be measured at what ag

Hello, younger children and infants who can't speak can also be examined, parents can check themselves through some methods, place various objects (including faces) in front of the infant's eyes, and suggestions: observe their gaze; Older infants and young children are very averse to covering one eye, so they can determine the quality of their vision by covering both eyes separately and observing the shaking of the head, crying, and changes in facial expression. In general, the eye with better vision is more violent, while the eye with no vision is unresponsive.

You can also place black and white stripes and gray pictures in front of your eyes, and babies and toddlers with good eyesight will choose the former. The above is an introduction to when it is better for children to have an eye examination, the sooner the vision is found, the better, and after the discovery, it is necessary to go to the hospital to do further simplicity, so as to achieve the purpose of early ** corresponding diseases.

How many days after birth can a newborn be screened for vision?

Vision screening of newborns is usually done within 3 to 5 days of birth. For newborn babies, the level of vision is very weak, and it is about a full month before you can see the figure of a person vaguely.

In addition, there are several key periods for your baby's vision examination:

1. At the age of 6 months.

The pediatrician needs to check for head-eye coordination and any possible eye conditions for all children who come to the 6-month clinic for routine outpatient check-ups. Between 6 months and 3 years of age, photographic screening may be able to detect early amblyopia and other risk factors.

2. At the age of 3-5 years old.

Children at this age should have an annual vision screening by a pediatrician. and to examine the eye for any kind of developmental defect that could affect future education.

3. At the age of 6 or older.

After the child reaches the age of 6, it is necessary to have a check-up every other year. These tests measure your child's vision and assess how well your child is functioning in various aspects of vision.

Nowadays, many children over half a year old will have an eye examination. The purpose is to better protect the child's eyesight and prevent the child's vision from declining. Of course, daily vision protection is naturally very important!

1. The time of close eye use should not be too long, every 40-50 minutes, you should take a little rest for 3-5 minutes, and look into the distance to relieve visual fatigue.

2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.

3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia. In addition, it is also necessary to pay attention to regular supplementation of eye vision nutrients, not from the nutrients required by the eyes, enhance the anti-fatigue ability of the eyes, and better protect the eyesight.

Fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to obstruct the vision of the hand shadow. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.

Generally, desktop lamps should be less than 40 watts.

5. Avoid reading while walking or reading in a walking car. Because the carriage is shaking, the body is shaking, and the distance between the eyes and the book cannot be fixed, the burden on the glasses will increase. Often, this is likely to lead to myopia.

6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.

Malnourished and weak children are prone to myopia.

7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.

8. Eat less candy and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

At what age should your child have his or her vision checked.

Children and adolescents should have an eye test every 6 to 12 months.

Adolescents who have myopia should go to the hospital for optometry and correction in time, and do not use glasses of substandard quality. The degree of myopia will increase with the age of the child, and the refractive status should be rechecked every six months to a year.

Outdoor activity for two hours a day or 10 hours a week can effectively reduce the incidence of myopia. While attaching importance to the problem of myopia in adolescents, do not ignore strabismus and amblyopia, and regularly check the visual acuity and refractive status, early detection and early detection.

Morning optometry is usually the best.

This is because when the eye looks at different objects near and far, it mainly relies on the contraction and relaxation of the ciliary muscle, and the thickness of the lens to adjust the focal length. After a full night's rest, the ciliary muscles can be completely relaxed, and the results of refraction are most accurate.

If you choose to use the eyes in the afternoon or evening, after a day of use, the ciliary muscles are in a state of fatigue for a long time, then the optometry glasses, the refraction results may be skewed. With such glasses, you may not feel any discomfort at the time, but after two or three days, you may experience dizziness and dry eyes.

It is advisable to check the eyesight in the morning, as the child has not overused his eyes and the eyesight is the best after a night's rest.

It's best when the child isn't sleepy.

Corrected visual acuity is generally more common to people with refractive error than uncorrected visual acuity. Uncorrected visual acuity is actual visual acuity, while corrected visual acuity is the visual acuity obtained after the refractive error is corrected with glasses. In other words, corrected vision is the vision after wearing glasses.

Visual acuity measured without glasses is called unaided visual acuity.

There are currently three main methods used to correct refractive errors: wearing glasses, contact lenses (OK lenses), and laser surgery**. Wearing eyeglasses is still the most commonly used, and its disadvantage is that it affects the appearance, but as technology continues to advance, spectacle frames are getting lighter and lighter, and spectacle lenses have evolved from glass lenses to plastic lenses that are widely used today.

Wearing glasses is still the safest way to correct your vision.

Generally speaking, a child can be screened for vision 3-5 days after birth. However, babies at this stage are still in a state of high farsightedness, and as they grow older, they may gradually approach normal, and they can generally be reached after the age of 6.

For babies at different stages, we do different methods of eye examination, here the experts of the twist angle vision screening system system will teach you a few tricks: because the baby under the age of 3 has not yet developed well in cognition, can not carry out a formal vision test, then we can do this method to carry out a simple screening: when the baby is about 2 months old, parents can make faces to them, in the case of normal vision, the general child will laugh when the baby is about 4 months old, Parents can hold the toy and shake it back and forth in front of their baby's eyes, and their eyes will move back and forth on the toy.

When babies are about 6 months old, they can basically reach for objects in front of them. When the baby is about 8 months old, parents can use their fingers to point to a place to see if the baby's eyes will see there.

Visual acuity assessment can be done after birth, but the usual E-letter eye chart visual acuity can usually be performed until the child has sufficient cognitive and expressive skills, and before that, infant vision assessment methods such as graphical eye charts, selective **, and visual evoked potentials can be used. E-letter eye chart visual acuity is usually done at 3 years of age. In the following cases, ophthalmologic examinations should be done as soon as possible after birth

1) Premature infants (2) have a family history of strabismus, amblyopia, high refractive error, etc., and (3) have any abnormalities in the appearance or visual performance of the eyes.

For babies around three years old, you can take her to have her eyesight checked.
