    Spherical lens refers to myopia.

    or the degree of farsightedness, cylindrical refers to astigmatism.

    The axial position is the direction of astigmatism, interpupillary distance.

    Refers to the distance between the pupils of two eyes.

    Spherical lens + cylindrical x-axis position + interpupillary distance = refraction power.

    As; The measured power of the right eye.

    Yes (r) spherical lens, cylindrical lens, axial position 95, corrected visual acuity is; The left eye (L) is. Spherical mirrors.

    Corrected visual acuity is the interpupillary distance (PD) between the eyes

    66 then the refraction power of the patient is.

    r;,l;PD = 66 corrected visual acuity is.

    All you have to do is take this prescription to the optician's shop and you can get a pair of glasses.

    SPH stands for spherical power, CYL stands for astigmatism, AX stands for astigmatism axis, OD stands for right eye, and OS stands for left eye.

    Explanation of optometry terminology:

    Interpupillary distance (PD): the horizontal distance between the two points in the center of the pupil of the left and right eyes.

    axis: The direction of astigmatism. Note: There is a astigmatism degree to accommodate the astigmatism axis; No degree, no shaft noisy and no bit.

    Corrected visual acuity (VA): refers to the visual acuity that is detected after glasses are fitted.

    Right eye) SPH (spherical) CYL (cylindrical) AX (axial position.

    Left eye) SPH (spherical) CYL (cylindrical) AX (axial) PD (interpupillary distance.

    61(mm)

    Myopia in the right eye. Combined astigmatism.

    The shaft position is 90 degrees.

    Myopia in the left eye without astigmatism.

    As the name suggests, interpupillary distance is the distance between the center of the pupils of the two eyes, and there is no normal abnormality. There is no fixed range, in my work in recent years, it is about 55-66, this is no problem, and it will not cause anything, everyone's situation is different, the interpupillary distance is naturally different, just like the body, some are a little fatter and some are a little thinner. (Yours is more common.)

    I'm exposed to 59-62 the most. )

    In addition, ax refers to the axis position of astigmatism, which is its diopter.

    The direction in which it is acting (the direction with the strongest diopter is perpendicular to the indicated axis.) The CYL in the left eye is 0 and there is no astigmatism. The shaft position is naturally Liang has failed and does not need to care about it.

    Your eyeballs have no problem with PD and AX, but you don't know how far you can see with this power, and the power you give is already very large.

    Hope your corrected vision.

    Can be a little higher hlm

    Your refraction result is 300 degrees of myopia and 225 degrees of astigmatism in your right eye, and the direction of astigmatism is 15 degrees. The left eye is 400 degrees myopia, 225 degrees astigmatism, and the astigmatism direction is 165 degrees. If the eyesight can only be corrected to the point where the eyesight is not up to standard, it is recommended that you further determine the reason for the unsatisfactory corrected vision.

    The axis position is the direction of astigmatism, 1-180 degrees, if the power is not the right axis position when processing glasses, it is not clear and uncomfortable to wear. Hope it helps.

    From this report, it can be seen that it is the result of dilated refraction, and the result is 300 degrees of myopia in the right eye, 225 degrees of astigmatism, and the axial direction is 15, and the best corrected visual acuity is. The left eye is myopic at 400 degrees, with 225 degrees of astigmatism, and the axial direction of astigmatism is 165, and the best corrected visual acuity is also. At the same time, it shows that the eye position is exotropia, which is the opposite of the esotropia of the so-called "cross-eyed".

    The axis position refers to the direction of the cylindrical mirror or astigmatism

    This is the result of dilated refraction, which shows that the right eye is myopic at 300 degrees, with 225 degrees of astigmatism, and the axial direction of astigmatism is 15, and the best corrected visual acuity with mirrors is. The left eye is myopic at 400 degrees, with 225 degrees of astigmatism, and the axial direction of astigmatism is 165, and the best corrected visual acuity with glasses is also.

    Right eye OD myopia astigmatism astigmatism axis 15 prescription.

    Left eye OS myopia astigmatism astigmatism axis 165 prescription.

    The best corrected visual acuity in both eyes is the visual surface.

    The myopia degree of the right eye is 300 degrees, the astigmatism is 225 degrees, and the astigmatism axis is 15; The left eye will also have a myopia degree of 400 degrees, a astigmatism of 225 degrees, and a astigmatism axis of 165. The axis position is the direction of astigmatism, which is generally perpendicular to the main meridian.

    The axis position is the direction of astigmatism, which is required when astigmatism.

    The optical axis indicates the axis position of astigmatism, and it will be comfortable to do it right, and it depends on the situation.

    Hello, from the data: the myopia degree of the right eye is 300 degrees, the astigmatism is 225 degrees, and the astigmatism axis is 15; The myopia of the left eye is 400 degrees, the astigmatism is 225 degrees, and the astigmatism axis is 165. The pivot position refers to the direction of astigmatism. Hope it helps!

    Hello, the astigmatism axis and interpupillary distance can be measured by instruments, and generally optical stores have computer refractors that can measure them. On the computerized optometry, as shown in the figure below, where A represents the astigmatism axis and PD represents the interpupillary distance. In this example, the right eye has astigmatism of 75 degrees and an axis position of 51; The astigmatism of the left eye is 75 degrees, and the axis position is 164.

    Interpupillary distance 63mm. Hope it helps.

    The first prescription: right eye degree myopia, degree astigmatism, axial position 17; 0 degree myopia in the left eye, degree astigmatism, axis position 10, interpupillary distance 67 mm.

    Second prescription: right eye + degree of hyperopia, degree astigmatism, axial position 170; The left eye is flat and has a millimeter interpupillary distance.

    The first prescription has anisometropia, and it is necessary to see whether the prescription needs to be adjusted according to the prescription of the old glasses and the prescription of the try-on situation.

    Prompt the eye industry, ophthalmology doctors, doctors, don't explain the degree of these questions, may delay the condition of many customers, prescription data is a very professional problem, the above data is a farsighted state, it is likely to be the key moment, if parents do not understand, take the results to get glasses is likely to delay a lifetime, but also remind parents that every time with glasses or without glasses, you should check the best vision once a year every six months, and you can't rely on feeling glasses.

    The optometry sheet is stated as:

    Myopia in the right eye is 100, myspora is 150, the astigmatism axis is 174, myopia in the left eye is 75 degrees, myspora is 100, and the axis is 24

    This is the power of the computer refractor, which is the initial data provided to the optometrist, which is not necessarily accurate, in order to accurately match the power of the glasses, the optometrist must further insert the film to determine.

    The axis of your right eye is 175 degrees, and the axis of your left eye is 24 degrees, and these axes are in the range of about 180 degrees, that is, they are in the horizontal position.

    Someone must have told you how to interpret overcounting!

    Myopia in the right eye is 100, astigmatism is 150, the astigmatism axis is 174, myopia in the left eye is 50 degrees, astigmatism is 100, the axis is 24

    This is the power of the computer refractor, not necessarily accurate, in addition, because the shaft position is calculated according to the 180 degree system, 0 degrees is equal to 180 degrees, in fact, the difference between 24 and 174 is only about 30 degrees, if it is manually adjusted may be closer!

    The power and axis position of astigmatism need to be measured rigorously and accurately to make it more comfortable to wear!

    Hope it works for you!
