    The right eye is hyperopic with 50 degrees of astigmatism and 125 degrees of astigmatism, and the axis of astigmatism is 78 degrees, which belongs to compound hyperopia astigmatism.

    The left eye has hyperopia of 50 degrees of astigmatism and 150 degrees of astigmatism axis of 77 degrees, which belongs to compound hyperopia astigmatism.

    I don't know how old you are, because children's eyeballs are not yet mature, the eye axis is short, so it is farsighted, must go through a development process, in order to become an emmetropic eye, children under 7 years old, if the degree of farsightedness is light, still do not need glasses, if the degree of farsightedness is higher, or even strabismus, it is necessary to timely optometry glasses to correct vision, so as to avoid the aggravation of amblyopia or strabismus in children, children over 7 years old, the degree of farsightedness still has a tendency to reduce, therefore, it is best to refraction once a year, and gradually reduce the prescription of glasses, This trend continues into near or after puberty.

    Even if it is better to have vision before wearing glasses than without glasses, the principle of glasses for farsightedness is to correct it as completely as possible.

    If you need to wear glasses, it will take less than 1-2 years to remove the glasses and return to normal. Now you must immediately refraction glasses, the sooner you wear glasses, the better, it is completely correctable, with the development of the child, it is expected to completely remove the glasses when he grows up, otherwise, it is easy to form amblyopia. If you have amblyopia now, you should be cured after glasses, generally it can be cured in a month, but you need to consolidate it for a period of time, you can wear glasses without amblyopia, and generally review it every six months, gradually reduce the prescription of glasses, and you may be able to take off your glasses when you are old enough to go to school.

    r stands for right

    L stands for Left (Left Eye).

    s stands for spherical power (myopia.

    Farsightedness. c represents the cylindrical power (astigmatism).

    a represents the axis position of astigmatism.

    Represents farsightedness.

    Represents the degree of myopia.

    VD is the check distance (unit SP).

    PD is interpupillary distance.

    Tested three times in each eye.

    Your left eye is myopic 150 degrees, astigmatism is 25 degrees, and the astigmatism axis is 151 You are myopic in your right eye by 100 degrees, astigmatism is 25 degrees, and the astigmatism axis is 7 degrees. b3

    The description of vision is generally myopia, farsightedness, presbyopia, astigmatism, and amblyopia.

    Generally, OD means right eye, OS means left eye, (- means secondary lens (concave lens), that is, myopia, (+ means positive lens lens, that is, convex lens, is farsighted.

    If the back number is the axial power of astigmatism, myopia is to see clearly in the near and blur in the distance, mainly caused by the change of the eye axis, the eye is called myopia after the parallel light enters the eye, focusing on the retina before the retina is called myopia, and focusing on the retina behind the retina is called farsightedness.

    After the occurrence of myopia and farsightedness, it is necessary to have a correct dilated eye refraction examination, exclude pseudomyopia and amblyopia, and pay attention to rest, correct eye use, and regular reexamination.

    Visual acuity is a kind of visual function, which includes, central vision, visual field, stereopsis, color vision, kinesthetics, etc., and the visual acuity commonly referred to refers to central vision. When checking visual acuity, the first thing to look at is whether the examination results are for distance vision or near vision, and then to look at distance vision, and near vision to check whether to check whether the naked eye vision or corrected vision (corrected vision with glasses) is checked. The last thing to look at is the left or right eye, or binocular vision.

    Usually OD means right eye, OS means left eye, and OU means both eyes.

    If you want to test the power of your eyes, you can go to the hospital for a subjective refraction test or an objective optometry test. Subjective refraction is mainly used for children under the age of 14 or adolescents. However, objective refraction is mainly a computerized optometry method, which is mainly suitable for adults.

    After determining the power of the eye, try to choose the right glasses to wear.

    The power of the eye is measured by a refractor, and the so-called power of the eye includes various states of refractive error, that is, myopia, farsightedness, and astigmatism, all of which have the existence of power, so this power is not like measuring eyesight, which can be measured by reading directly through a table. In fact, the eye power measurement must be refraction to know, the results given by optometry are relatively objective, compared to the visual acuity measurement is mainly objective. At the same time, the machine will give a prescription, and after the machine reading, the optometrist will perform insert refraction or comprehensive refractor for further refraction.

    The combination will determine what the prescription will be if you want to wear glasses. Therefore, sometimes the power of the eye, such as finding out that it is 500 degrees of myopia, does not mean that you have to wear 500 degree myopia glasses, it is possible to wear glasses only 450 degrees or 425 degrees, it is possible.

    To measure the power of the eye, it is best to go to the ophthalmology department of the hospital for testing, or you can go to a special optometry and optometry institution to do the test, so that the results are more accurate, and you can choose according to your own situation.

    Re-occurrence of vision loss after myopia eye surgery is usually seen in the following conditions:

    1. If similar manifestations occur in a short period of time, it is generally considered to be caused by local complications, such as corneal edema, corneal interlaminar debris, overcorrection and undercorrection, infectious keratitis, etc., which need to be checked and confirmed by a hospital. Clause.

    2. If a similar manifestation occurs again long after surgery, it is generally considered that there is refractive dystrophy.

    Generally, there are certain requirements for the writing of the list gauge of optometry, such as OD 200 + 100 * 75 =. This means that the right eye is a concave lens, that is, myopia is 200 degrees, astigmatism is 100 degrees, the astigmatism axis is 75 degrees, corrected visual acuity is 250 degrees, and the left eye is myopia 250 degrees. Negative 150 degrees of astigmatism and the axis of astigmatism is 100 degrees, and the corrected visual acuity is.

    Generally, the negative one indicates the concave mirror, and the positive one indicates the convex lens, the concave lens is myopia, and the concave lens is farsightedness. The principle of myopia is that the eye is not adjusted, parallel light rays enter the eye, and focus on the retina, which is called myopia. Myopia is a problem caused by changes in the eye axis.

    Meaning of the symbol on the optometry:

    S: Spherical (power of myopia or farsightedness) C: cylindrical cylindrical (power of astigmatism) A:

    AXLS axis position (the direction of astigmatism, if there is astigmatism, there is an axis position) VA:vision vision (the degree of clarity of seeing objects, such as auto:automatic computer automatic refraction (as a premise of comprehensive refraction, the power of the human eye is preliminarily determined).

    sub:subjective comprehensive refraction is a subjective examination (detailed examination of the condition of the eyes and fundus, checking the power of the human eye, and generally the final prescription for glasses).

    PD: Pupillary Distance (mm)

    d:distance for interpupillary distance.

    R (right) or od: indicates the right eye.

    L (left) or OS: for the left eye.

    The degree is expressed by d, which is commonly referred to as 100 degrees.

    : for farsightedness, -: for shortsightedness.
