Can 275 degree astigmatism be corrected at the age of 4

More than 200 degrees is already a high degree of astigmatism, and it needs to be paid attention to.

Studies have shown that the most common manifestations of astigmatism in the eye are:

1. The blurred image on the retina needs to be constantly finely adjusted, and the vision is distorted, so astigmatism, especially for farsighted astigmatism, is prone to visual fatigue. Presents with eye pain, tearing, headache, especially in the forehead, double vision, and short-range work that cannot be sustained.

2. Patients with highly asymmetrical astigmatism in both eyes, in order to see more clearly, often adopt a tilted head position to cause strabismus, which can be recovered after astigmatism correction. Patients sometimes move objects closer to the same place as a nearsighted person in order to obtain a larger image of the retina.

3. People with high astigmatism often squint when looking at distant or near targets, so as to achieve pinholes and fissures to improve their vision. Seeing through pinholes or fissures can reduce the impact of astigmatism on vision.

Astigmatism refers to when the eye is adjusted to rest, after the parallel light rays are refracted by the eye, due to the different refractive power of each meridian of the refractive system, causing different degrees of convergence, so it can not be concentrated on the retina, but at different distances to form two intersecting lines, the distance between the two intersecting lines represents the degree of astigmatism, because the retina is only presented as a hazy ring or a line, so the patient feels blurred regardless of farsightedness and near-sightedness.

Astigmatism**:

1 Mild regular astigmatism does not need to be corrected if there is no eye fatigue or blurred vision, but if there is any discomfort above, it should be corrected even if the prescription is not high.

2 High astigmatism should be corrected with cylindrical scope, if not suitable for all correction, can be given a lower degree, the general common method is to take drugs, usually the doctor recommends taking Leyan vision nutrients, warm water, insist on taking for a period of time, astigmatism can be reduced.

3 Irregular astigmatism cannot be corrected with a cylindrical lens, and contact lenses can be tried.

Eye myopia is more than 200 degrees, near vision should be blurry, affecting near vision, reading books, looking at computers will cause fatigue, easy to lead to myopia aggravation, or timely correction of glasses. Optometry glasses are recommended, if not corrected, it may aggravate myopia, resulting in an increase in prescription and blurred vision. It is recommended to pay attention to eye hygiene, read books, look at the computer for about 45 minutes, and rest for 10 minutes.

It is not serious for adults, it is more serious for such a small child, if the degree is high, you have to wear glasses, as a parent, you must pay attention to the child's eye habits, and take care of your eyes from a little bit!

This is already in the category of mild myopia, if the degree of astigmatism is within the range of 50 degrees, then the problem is not big, as long as the myopia is corrected in time.

This power, for now, can be done without glasses, but it is also necessary to pay attention to:

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.

If you are short-sighted, you can choose coated resin lenses with better light transmittance. Guidance.

It is necessary to pay attention to the rest of the eyes and use them reasonably. Usually read in a correct posture, with a distance of one foot, rest at intervals with your eyes, do not read in a dark light, and do not lie down to read a book or a movie.

Glasses are required.

Astigmatism simply means that the eye is not well developed, and there is a phenomenon of unevenness. And now there are more and more children with astigmatism, and children's astigmatism is directly related to the serious lack of vision nutrients, as well as bad eye habits.

Children with astigmatism first need to supplement vision nutrients in time, it is recommended to take Lejing vision nutrients, twice a day, one pack each time, take it with warm water, insist on taking it for a period of time, and astigmatism will gradually recover.

The other is to develop good eye habits.

1. Regular eye examination 1 2 times a year. Instruct young children to practice good hygiene and not to contact their eyes with their hands or chemicals. When reading, there should be plenty of light, preferably from the left rear; Correct posture and a distance between 30 cm and 40 cm.

2. When choosing reading materials, the font should be clear and not too small.

3. Watching TV must be 5 7 times the diagonal of the TV picture. Read a book for no more than one hour in a row. If you need glasses, you should be examined by a doctor and then dispensed with glasses.

If it is astigmatism, it should be caused by congenital development, if it is normal for you, you can observe it first, without special **, you can wear glasses when necessary.

It is normal for young children to have astigmatism, because the child's eye is not fully developed, the osclera of the eye is not enough to expand the ocular contents, and the scleral strength is much worse than that of adults, so the eye is squeezed by the upper and lower eyelids will form obvious lateral astigmatism (the axis of astigmatism is close to 0 or 180°).Under normal circumstances, the magnitude of astigmatism in children is about the same, and the axial direction of the left and right eyes is basically symmetrical。The astigmatism will gradually decrease as the child grows and the eye develops, reaching normal around the age of 12.

If the astigmatism axis is longitudinal (close to 90°) or oblique (45 135°), this should be noted. High astigmatism in one eye should also be a cause for concern to prevent amblyopia or strabismus from occurring.

It can be corrected. It is recommended to go to a regular hospital or a regular optometry center to have a comprehensive examination of the child's vision and visual function, so as to better solve the problem of wearing glasses. In addition, it is necessary to review on time in the later stage, and the general review cycle is three months.

It is recommended that you try wearing orthokeratology lenses for your child. Wearing orthokeratology lens is a special design of hard lens, that is, OK lens, through the "reverse geometry" design of the lens, that is, the special design of the flat periphery of the lens curvature, in the way of mechanical compression or massage, so that the radius of curvature of the cornea becomes larger, so as to achieve the purpose of reducing the refractive power of the cornea.

The main function of the OK mirror.

1. Rapid, safe and effective correction of moderate and high true myopia;

2. Better correction of mild regular astigmatism;

3. Effectively prevent the deepening of myopia in adolescents;

OK Mirror Correction Effect After three months of correction, the OK technique will have the following results:

1. Most patients quickly recover their visual acuity to the formal eye within 2 weeks (i.e., the visual acuity is reached.

2. Some patients show a gradual decline, that is, a gradual decrease of 300-500 degrees within 3 months.

3. A very small number of patients have poor results due to too flat cornea, axial myopia, or inability to ensure sufficient time.

OK mirror** is suitable for people.

1. Suitable for ages 8-40, especially adolescent myopia patients.

2. The degree of myopia is within 900 degrees, and the degree of astigmatism is less than half of the degree of myopia.

3. No eye inflammation, no dry eye disease, glaucoma and other eye diseases.

My son is only two years old this year and has 350 degrees of astigmatism, can this be corrected and recovered?

It is normal for children of this age to have a certain amount of astigmatism, and it is recommended that you have regular check-ups after a period of time to see if it will decrease, and go to a regular eye specialist hospital for examination.
