The power of the eye, how to calculate the power of the eye

I don't think my vision will recover on its own, unless it is pseudomyopia, and the degree of myopia will not become shallow. In your case, I recommend that you wear suitable glasses to correct your myopia.

Once glasses are fitted, they should be worn in addition to washing their face and sleeping, because patients with myopia are in a state of emmetropia after wearing suitable glasses, and the adjustment and divergence function are restored to their natural relationship. Wearing glasses is not only to improve eyesight, but also to read and work at an appropriate distance, so that there is a normal coordination between the adjustment and divergence functions of the eyes, and to avoid eye fatigue.

In fact, the correct wearing of glasses will not go deeper and deeper, and the development of visual eye power is not directly related to wearing glasses. Patients with myopia wear appropriate glasses and pay attention to eye hygiene, and the degree of myopia will stabilize at a certain level. However, if you think that everything will be fine with glasses, and you do not pay attention to eye hygiene and continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and myopia deepening.

In addition, wearing inappropriate glasses, such as no refraction or inaccurate refraction, and excessive prescription, will increase the burden on the eyes, reduce vision, and deepen the prescription.

Surgery to correct vision is not recommended!! Finally, I hope it can help you!!

For refractive error, a detailed medical refraction should first be performed. If the results of small pupil refraction are suspicious, dilated refraction should also be performed. In addition to optometry, it is also necessary to check the eye alignment and adjustment.

As for how to calculate the prescription of glasses, it is not only based on the results of refraction, but also according to the position of the eyes. If it is a patient with internal oblivion, the degree of myopia should be low-corrected, and the farsightedness should be corrected by the foot. If it is a patient with external heteropia, myopia should be corrected by foot, and farsightedness should be corrected by low.

If the adjustment is ACA, the myopia should be low-corrected and the farsightedness should be corrected for the far-sighted. If ACA is too low, myopia should be corrected for foot, and farsightedness should be low-corrected.

Myopia can manifest as decreased visual acuity, and the prescription of the myopic eye can be determined by refraction examination, and no calculation is required. After the formation of myopia, it is necessary to wear glasses with appropriate prescription according to the results of refraction, and develop good eye habits to control the continuous growth of prescription. After the age of 18, if the prescription is relatively stable, laser surgery or lens implantation can also be used to normalize the corrected visual acuity of the eye.

In childhood, the body is in the stage of growth and development, and the degree of myopia will increase with the increase, relatively faster than that of adults. It is recommended to wear orthokeratology lenses to compress the cornea through its own hardness, which can control the elongation of the eye axis, thereby controlling the continuous growth of myopia.

In any case, it is best to keep the eyes of the dominant eye unchanged, and finally achieve the goal of seeing clearly, persistently, and comfortably after wearing glasses.

Your list is simply understood as 250 degrees for the right eye and 350 degrees for the left eye.

l indicates the left eye, r the right eye; "Indicates farsightedness," - indicates nearsightedness.

S(sph) represents the spherical value, which is the degree of myopia, and 1 means 100 degrees of myopia.

C (CYL) represents the cylindrical value, that is, the degree of astigmatism, that is, myopia astigmatism 10 degrees.

a(ax) indicates the axial direction of astigmatism, and the axial direction is horizontal in most people.

PD: Interpupillary distance 60mm VD: Spectacular eye distance of 12mm SE stands for spherical lens, that is, myopia and farsightedness.

You should ask the teacher in this area, or a professional in this area, or go directly to the optical store and ask, they will know what the power of your eyes is. This should not be very high.

The power of myopia is not calculated but obtained by doing a refractive examination, and it is best for children under 12 years of age to do dilated refraction after cycloplegia, and for adolescents over 12 years of age, they can do rapid dilated refraction.

Adults, such as 30-40 years old, can do a medical refractive examination, after passing the examination, you can obtain a more accurate refraction, you can know how many degrees of myopia or whether it is farsighted, whether there is astigmatism, through the medical refractive examination can be obtained.

If you have an exact refractive power, you must wear glasses as soon as possible to improve corrected vision and prevent fatigue when using your eyes in the future.

The power of the eye is calculated after we go to the eye center and go through a vision test.

Generally, it is 500 degrees of myopia, and the farthest distance that can be seen with the naked eye is only 20 centimeters.

Logarithmic visual acuity, equivalent to decimal point vision, myopia is about the reciprocal of decimal point visual acuity multiplied by 100, called 250 degrees. Visual acuity is not completely consistent with myopia, because the intensity of eye accommodation is different, and the visual acuity should be 100 degrees or 300 degrees. To make a clear diagnosis, dilated refraction is required, and accurate myopia can be obtained by using cycloplegic agents, such as atropine eye drops or tobiamide eye drops, to paralyze the ciliary muscle and relieve the spasm of the ciliary muscle.

When the first myopia occurs, it is necessary to diagnose true or false myopia, it is recommended that you go to the optical center for examination, and then you can determine the degree of myopia, if you want to know how many degrees of ten centimeters of your eyes are, you must go to the hospital for dilated refraction, because it is difficult to infer a very accurate degree through this specific symptom, and it is difficult to infer a specific naked eye vision through a specific degree, so if you want to know how many degrees, you must go to the hospital for dilated eye refraction.

All the means of improving the patient's vision are called vision correction methods, and the common methods are:

1. Wear appropriate glasses.

2. Increase outdoor activities.

3. Use low-concentration drugs, such as atropine, etc.

4. Teenagers can choose to wear orthokeratology lenses (OK lenses).

The reciprocal of the focal length of the eye (the distance from the imaginary focus to the lens) is the power of the lens, and the value of the lens power of 100 is the power of the eye.

Note: The power of myopia lenses is negative, and the power of farsighted lenses is negative.

Well, I know, you go to the doctor, the doctor told you to look at the e after the prescription is over, the doctor didn't tell you to wear glasses! Then you are going to the doctor and asking, 'Doctor, why am I myopia, how far am I nearsighted, you can tell me about it?' That's it!!
