What are the items of the children s vision test?

A comprehensive optometry examination, in addition to the general visual examination, also includes binocular coordination, visual field, intraocular pressure, color vision, and internal and external eye health.

1) Vision examination. Measure ** visual acuity, check whether adolescents and children have myopia, farsightedness, astigmatism, amblyopia and other problems, and prescribe prescriptions.

2) Field of view. If the visual nervous system is damaged, the visual field will be narrowed, through visual field examination, when the patient's eyes are looking forward, the ophthalmologist will place the fingers or objects on the top, bottom, left and right, to check the breadth and visual acuity of the visual field, which can help to find out the symptoms of glaucoma, retinal pigmentation lesions, cranial nerve tumors and so on.

3) Strabismus examination. Strabismus people cannot look in the same direction with both eyes at the same time and cannot effectively aim at the target at the same time. An optometrist examines eye movements to check for strabismus.

4) Binocular coordination. Using polarizers and stereo vision examination charts, the eyes with normal vision and good coordination between the eyes can point out the three-dimensional patterns on the map, and those with insufficient stereoscopic vision have a weak ability to judge the distance of objects.

5) Color vision. A colour vision chart is used to test the ability to distinguish colour and whether you have colour deficiency or colour blindness.

6) Focusing ability. Use a near-point focus meter to measure the ability to focus near objects, check the function of the ciliary muscle, and check whether there is hidden hyperopia; In addition, you can also check the aggregation ability of the eyes, if the eyes do not have the ability to aggregate, the eyes will be tired easily when reading.

7) Physiological microscopy. Check the health of the cornea, conjunctiva, anterior chamber, and lens.

8) Intraocular pressure test. Measuring intraocular pressure with a tonometer can help diagnose glaucoma. As there are no obvious symptoms in the early stage of glaucoma, regular check-ups can help to detect the disease early and reduce the risk of blindness.

9) Fundus examination. The pupil is dilated with eye drops, and then the retina of the fundus, optic nerve, and fundus blood vessels are observed with a special instrument to check for fundus hemorrhage, narrowing of blood vessels, or other lesions.

Generally, it is recommended that children have a preliminary vision screening at the first 3-5 days of life to find out if there are problems such as amblyopia, strabismus, and congenital vision hypoplasia. If everything is normal, by the age of 3 years, the examination will be done again to ensure the healthy development of the child's vision during the critical period of vision development.

The most common use of distance vision examination is the international standard eye chart, and the standard for normal vision is that if the patient's visual acuity is found to be lower during the examination, a small hole glass is often worn for further examination. If the patient's visual acuity is low, or there may be factors affecting visual acuity, a comprehensive distance, near, and corrected visual acuity examination of the test eye is required to determine the degree of visual impairment. Near vision examination is a reading vision test, and its purpose is to compare with distance vision, which can clarify some diagnoses (such as refractive error, presbyopia, etc.), and can also accurately assess the activity and reading ability of the person being examined.

For example, newborns can use "light chasing" examination or observe pupil light reflex, 1-month-old children can actively browse around things, and 3-month-old children can do fixation examination. Optokinetic nystagmus tests are more commonly used to assess visual acuity by observing the child's gaze at a wide and narrow bar. Visual acuity examination is of great significance for the diagnosis of ophthalmic clinical diseases, and it is necessary to choose the examination method and test items according to the patient's age and eye health status.

Where do children go to check their eyesight, with the increase of electronic products, now more and more children have problems with their eyesight, and now many students wear glasses. However, when children are young, they don't know if they have problems with their eyesight, because their ability to express themselves is limited. If parents feel that their child's vision is wrong, where should they take their child to have their vision checked?

Where the child goes to have his vision checked

To check your child's eyesight, it is best to go to the eye department of a children's hospital. Children over the age of 10 can dilate their pupils quickly, but children under the age of 10 cannot dilate their pupils quickly. If you go to the local regular hospital for eye examination, you can do an eye examination, including eyelids, eyelashes, conjunctiva, pupils, fundus and intraocular pressure, etc.

In addition, parents should pay attention to correctly guiding their children to use their eyes healthily to prevent the occurrence of myopia.

At what age should children have their vision checked

1. The critical period of eye development is before the age of 3, and the sensitive period is before the age of 9.

2. Around one year old, regardless of whether there is a vision problem or not, the health care doctor will recommend that parents (especially if both parents are highly myopia) take their children for a vision examination, if there is a problem, the success before the age of 3 is very large.

3. After the age of three, it is recommended that parents take their children to do a dilated eye refraction to understand their children thoroughly. Eye health.

Where the child goes to have his vision checkedGenerally speaking, parents can take their children to the hospital or a regular optical store to have their vision checked. Of course, if the vision problem is caused by the disease, then you must go to the hospital for examination as soon as possible to avoid delaying the best time.

In addition, parents should occasionally remind their children to take care of their eyes and help them change their bad sitting posture or living habits.

To check your eyesight, you need to choose a hospital to visit an ophthalmology clinic. Adult vision should be above the level, if the vision is blurred, the vision needs to be checked, and the general ophthalmology clinic can be selected for routine examination to confirm the diagnosis. There are many specialties in professional eye hospitals, and if you need to choose a specialist clinic, you also need to choose according to the specific symptoms, such as adolescents and children, who may have myopia, because they may need to undergo optometry examinations, consider choosing an optometry clinic.

Middle-aged and elderly patients with gradual vision loss in their eyes, which may be caused by cataract or fundus lesions, can choose a cataract specialist or fundus medicine department, if glaucoma is suspected, you can choose a glaucoma specialist. China's ophthalmic medical resources are seriously scarce, the number of patients with eye diseases continues to increase, and many patients cannot get timely and effective.

Retinopathy occurs in 30% of diabetic patients, with a blindness rate of up to 30%, and about 33 million potential patients;

The prevalence of glaucoma in people over 40 years old is about 16 million potential patients;

The prevalence of age-related macular degeneration is about 40%, and the potential patients are about 30 million;

In response to such scenarios, Lingyi Zhihui has launched a smart fundus screening program to help patients with eye diseases be screened and diagnosed early and reduce the risk of blindness.

As parents, we are most concerned about the health of our children, and most parents will take their children for regular eye check-ups. But after the examination, I got the child's vision examination report, but it was difficult because I couldn't read it at all. How do I read my child's vision test report?

Come and see what the experts of the Twist Angle Vision Screening System have to say.

In fact, it is not difficult to understand the child's vision test report, you only need to figure out the meaning of the letters on the eye test report, and the meaning will be understood.

Before looking at the child's vision test report, we need to figure out the left and right eyes. On the vision test report, the letter R (sometimes written OD) is the abbreviation of right, which represents the right eye. The left eye is written with L** (sometimes written as OS), which is an abbreviation for Left.

The s in the inspection results are the spherical lenses that are represented. If it's a + sign, it's farsighted, and a - sign means 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, which 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.

In addition, in addition to these letters, there are also some numbers that 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.

r is the right eye with 25 degrees of farsightedness and 50 degrees of astigmatism.

l is the left eye with 50 degrees of hyperopia and 75 degrees of astigmatism.

It is necessary to know the age of the child, if the age is relatively young, it is not excluded that it is the possibility of physiological hyperopia, which generally has a physiological farsightedness before the age of 6.

However, if the astigmatism exceeds 50 degrees, it should be paid attention to, because the general physiological astigmatism is the degree within 50 degrees.

Suggestions: Astigmatism simply means that children's eye development is not good, and there is a bumpy situation, which is the need for timely oral eye vision nutrients, supplement eye nutrition, fundamentally promote eye development, so as to control or improve astigmatism.

A child's vision test is the same as an adult's vision checklist, and the results are often expressed in letters and numbers. The common letters and numbers on the vision test sheet mean that V means visual acuity, OD means right eye, OS means left eye, and OU means both eyes.

In addition, R is often used to represent the right eye and L to represent the left eye, for example, a certain vision test sheet says V:,, which means that the visual acuity of the right eye is and the visual acuity of the left eye is. If there is too much difference in vision between the two eyes or if vision is poor, an eye examination should be done to determine whether there is refractive error, amblyopia and other problems.

This list looks very good! 0:25 0:50 are all normal!

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.

Such as: computerized refraction, comprehensive refraction, intraocular pressure, slit lamp examination, dilated refraction, visual function examination, strabismus examination, isoscopic examination, etc.

1. Pay attention to the time you spend with your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and acupuncture acupuncture points of Chinese medicine, combined with jujube Kuanhui medical sports, which is a scientific method to protect eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to eye nutrition.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

Regular check-ups are due to the fact that children's eye structure, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content of the examination is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.

The initial diagnosis of myopia in children is a routine eye examination, fundus examination, and eye length examination. Among them, slit lamp examination is a routine ophthalmic examination, followed by dilated refraction, and the mydriatic agent for optometry varies according to age.
