What do children do when they have eye exams?

As parents, we need to undergo an eye examination when our children are about one year old, and this vision examination can help us understand whether the child is born with strabismus, amblyopia, or congenital deficiency. If you have any of these problems, this is the best time to do it. If everything is normal, by the time the child reaches the age of 3, a comprehensive vision examination is required again, and when the child is 6 years old, he or she will enter primary school, and a comprehensive examination is required.

Specific items to be examined include:

1) Vision examination. Measure the visual acuity, so that you can find out whether the child has myopia, astigmatism, farsightedness, presbyopia and other problems.

2) Field of view. Each of us has a dominant eye, each eye sees a different range, if the optic nerve in one eye is damaged, then the field of vision will be reduced, through the visual field examination, you can check the breadth and visual acuity of the field of view, but also help to find out whether there are retinal pigmentation lesions, glaucoma, cranial nerve tumors and other symptoms.

3) Color vision. A color vision chart can be used to test the ability to distinguish colors, and you can tell if your child has color deficiency or color blindness.

4) Binocular coordination. This method is to use polarizers, stereo vision inspection chart, only normal vision and good coordination of the eyes can accurately point out the pattern on the **. If the child's stereoscopic vision is poor, he will not be able to recognize the pattern.

5) Focusing ability. This project is mainly to check the function of the child's ciliary muscles and find out if the child has farsightedness.

6) Strabismus examination. Children with strabismus cannot look at the same position with both eyes at the same time, and cannot focus on the target in a limited way. An optometrist observes eye movements to check for strabismus.

7) Physiological microscopy. It can determine whether the cornea, conjunctiva, anterior chamber, and lens are healthy.

8) Intraocular pressure test. If the intraocular pressure is too high, you are prone to glaucoma, and the older you are, the greater the chance of developing glaucoma. Regular check-ups can help to detect the disease early and reduce the risk.

9) Fundus examination. Observe the optic nerve, retina, and fundus blood vessels of the fundus with an instrument to check for fundus hemorrhage, narrowing of blood vessels, or other lesions.

An eye exam includes a number of items that can help us understand the condition of your child's eyes as comprehensively as possible and ensure the health of your child's eyes.

The E-chart visual acuity test is a part of the optometry examination, which includes a series of eye examinations such as naked eye vision examination, computerized refraction, axial length examination, and ocular position examination. Based on the results of these tests and your child's condition, the doctor will decide whether further tests are needed.

ZEISS Myopia Prevention and Control Clinic, focusing on the prevention and control of myopia in children and adolescents aged 3 and 18, provides comprehensive eye health examination knowledge, teaches you to read optometry data, understand the visual acuity, and intimately sets up refractive development file management tools, so that you can track your child's vision health at all times. [Scan the code to follow, experience it immediately].

Right eye: 125 degrees hyperopia reserve, 25 degrees astigmatism.

Left eye: 175 degrees hyperopia reserve, 25 degrees astigmatism.

At present, the child's vision is normal.

The child is still young, and the farsightedness reserve should be protected, and the child should be checked every six months to understand the farsightedness reserve and prevent and control myopia. Usually during the day, you must let your child stick to the outdoors, accumulating 2 hours or more every day.

The right eye is 125 degrees farsighted, and the left eye is 175 degrees farsighted, and the vision is normal.

(1) Vision examination for infants under 6 months old.

Babies under 1 month of age: able to gaze at light sources. At a distance of 20 30 cm from the baby, use a flashlight to illuminate the baby's pupils. The pupils of normal babies can be narrowed and enlarged, which means that they have a response to light.

1 3-month-old baby: can pay full attention to the faces of people around them, actively look at things around them, can look at horizontal and vertical balls when lying down, and can see moving fingers.

3 6-month-old babies: can actively grasp things of interest with their hands, can follow the sports ball 30 60 cm away in front of the eyes, and when the adult's fingers suddenly approach the baby's eyes, the baby will have a protective blinking action.

These tests are not quantitative, but can only be roughly estimated.

2) Vision examination for 6-month-old and 2-year-old infants.

- Optokinetic nystagmus: Infants and young children are tested for visual acuity with a test drum coated with a black-and-white stripe. Turning the test drum in front of the infant's eyes and varying the width of the black and white bars induces nystagmus in infants and toddlers, so as to approximate the infant's visual acuity.

Ball estimation method: This method is to use white balls of different diameters on a black background to let children identify, so as to roughly estimate the visual status of infants and young children: a small ball with a diameter of centimeters can be distinguished at a distance of 3 meters, and the vision is equivalent to that on the E word table; Able to distinguish small balls in centimeters in diameter, visual acuity is; Able to distinguish small balls in centimeters in diameter, visual acuity is; Able to distinguish small balls in centimeters in diameter, visual acuity is; Able to distinguish small balls in centimeters in diameter, visual acuity is; Able to distinguish small balls in centimeters in diameter, visual acuity is;

3) Vision examination for 2-year-old children.

Visual estimation method: 30-35 cm in front of the child's eyes, place beads of different diameters. If a toddler can find and pick up a small bead with a diameter of 1 mm, his or her vision is above that.

Children's Graphic Eye Chart Method: It is drawn from the flowers, birds, animals or objects that children are most interested in, and is used instead of the E-word chart to measure children's eyesight.

4) 3-year-old children's eye examination Accurate vision examination can be performed with a children's graphic eye chart.

5) 3 4-year-old pediatric eye examination Accurate visual acuity examination can be performed with a children's graphic eye chart. Children over the age of 3 should be taught to recognize the E-chart as much as possible, and try to gradually transition to the use of the international standard eye chart.

Nowadays, most children can't do without their mobile phones every day, or they watch TV every day, so children's vision problems have become a major concern for many parents. In order to let go of their suspense, many parents take their children to the hospital for an eye examination, but the results of the examination are not clear. What about the results of a child's vision test?

Before looking at the results of a child's vision test, it is necessary to figure out the left and right eyes. On the results of the vision test, the letter R is the abbreviation of right, and it is sometimes written as OD, which represents the right eye. The left eye is written with L**, which is an abbreviation for left, and is sometimes written as os.

The s in the inspection results are actually the representative spherical lenses. If it's a + sign, it's farsighted, and a - sign is myopia.

There is also a letter C on the examination results, which is the abbreviation of cylindrical, which means cylindrical, which represents the condition of astigmatism. If it is +, it means farsightedness astigmatism, and - it is myopic astigmatism. The letter A is the abbreviation of AXIS, which stands for axis position and indicates the direction of astigmatism.

Then find VA, which is the abbreviation of vision, which stands for children's vision, that is, the clarity of seeing things. There are also some numbers, which represent the corresponding degrees. Parents can judge whether their child's vision is normal based on specific data.

If there is anything different from the standard value, it means that the child has a vision problem and can consult a doctor.

Ophthalmology. Go to the waiting area of the ophthalmology (optometry center) and wait for the number to be called or the display screen shows your number, and then go to the corresponding consultation room for examination. If it is an ordinary visual examination, a few minutes to more than ten minutes is enough, if you still want to see the fundus, you need to dilate the pupils, and drop mydriatic drugs such as post-matropine on the conjunctiva, the examination technician will ask to wait for a while to come back for examination, which takes about half an hour.

For vision examinations, visual acuity examinations should be performed at moderate light levels, and the examination room should be dimly lit. When illuminating the eye chart, the examiner should be mindful of the state plexus to avoid glare in the patient's field of view. At present, the common liquid crystal or projection eye chart has no code and has strict restrictions.

The most important thing is to check the visual function in depth, and secondly, accurate computer refraction is essential, it is best to assist in checking the eye axis and corneal topography and other tests, the more comprehensive the more clear the understanding of the child's eyes, I hope the child can have a clear vision of the world!

A standard visual acuity test includes both distance and near vision.

1) Check distance vision: China usually uses the international standard eye chart and the logarithmic eye chart created by Miao Tianrong in China. During the examination, the examinee sits at a distance of 5m from the eye chart, and the international standard eye chart or logarithmic eye chart is at the same level as the eye being examined, and both eyes are examined separately, first right and then left, from top to bottom.

The examinee quickly states the direction of the optometric notch and records the font size of the line of the smallest optometric that is correct. Normal human vision is or. When the visual acuity is lower, the visual acuity chart can be gradually approached and the visual acuity can be calculated (d is the distance from the eye chart when the subject sees the line clearly).

If you see clearly at a distance of 3m, your visual acuity is. When visual acuity is lower, i.e., when discerning is not available, the exponential (fc) distance is changed. If the index is not recognizable at 5cm, the manual (hm) distance is changed to a manual (hm) distance.

If you don't feel the manual work, you can use a candle or flashlight to illuminate your eyes in a dark room to record the light perception (LP) or no light perception. If there is light sensitivity, a light positioning test should be done.

2) Check near vision: China usually uses Jaeger's near eye chart and the E standard near eye chart designed by Xu Guangdi in China. The eye chart should be placed in a well-lit place, or illuminated with fluorescent lamps.

A normal person can see the 10th act clearly at a distance of 30cm in normal light.

If the distance between the eye chart and the eye has been changed due to nearsightedness or farsightedness, the distance changed will be recorded together.

If you want to check your eyesight, it's actually very simple. As long as you go to the ophthalmology department of the hospital for a medical optometry, you can know the vision of your eyes.

Why go to the hospital for medical optometry?

Because medical optometry is examined according to a rigorous medical optometry process; Determine the truth or falsity of the patient's myopia; Check for eye diseases such as strabismus and amblyopia; control diopter development, improve visual quality, and alleviate eye fatigue; Finally, a scientific optometry prescription is issued to achieve the purpose of wearing glasses clearly, comfortably, beautifully and healthily;

It may be related to excessive mental tension, too much stress, lack of outdoor exercise, unreasonable use of eyes, and other vision loss. It is recommended that you can choose the ophthalmology department of a regular public hospital to check your eyesight, and if you do have a problem with your vision, it is recommended to do further examinations, including optometry, slit lamp, intraocular pressure and fundus, and choose the corresponding ** method according to the examination results. And be sure to use your eyes reasonably, control the use of mobile phones, computers and other delicate eyes.
