Can I change the interpupillary distance of my glasses, I think there is a problem with the interpup

Interpupillary distance after glasses are assembled.

Basically fixed, if you want to make a relatively large adjustment, you can only change the frame, I think if the interpupillary distance difference is relatively large, you should find a business to rematch a pair of lenses, if the error is about 2-3mm, it doesn't matter much, if your power is low, the allowable error can be greater. The specific requirements are required in the eyewear assembly industry standard. "My IPD is 60 and the optician has given me 64, is that harmful to my eyes?

I was uncomfortable with glasses, so I went to the optical store to check, but the store that matched me with glasses said that it was normal, so I went to other optical stores to check, and other optical stores said that the interpupillary distance of the glasses I wear now is 64, and the interpupillary distance of my naked eye is 60! It's going to hurt my eyes, right? What should I do?

This is the situation reported by a netizen.

The purpose of measuring the interpupillary distance is to make the optical center distance of the lens consistent with the pupillary distance of both eyes, so that the wearer can wear it comfortably, otherwise the prism reaction will occur, and the wearer will have visual fatigue and dizziness.

Nausea and other symptoms. It depends on the individual's physique, you can try on glasses to see if it is clear, if you see the object is not clear, you should match glasses according to the specific situation.

If you wear glasses with interpupillary distance error for a long time, your eyes will get tired easily, and the prescription will increase over time. Some optical stores, in order to make the dispensing more lightweight, tend to increase the interpupillary distance. Therefore, it is recommended that consumers must go to a reputable and well-known optical store or online ** when buying glasses.

After getting the matching glasses, try them first, if there is something unsuitable, you must find after-sales, you must not wear uncomfortable glasses because you are afraid of trouble, the eyes are the windows of the soul, and we need to take care of them with our hearts.

The interpupillary distance of the glasses is not enough to be changed, and the interpupillary distance is the focus of the two lenses. Change the center focus to make the original frame bigger, unless you replace a large-framed glasses with a very small one.

Glasses belong to one-time processing, one-time molding, and the interpupillary distance error is also a national standard.

Your interpupillary distance is the national standard, and the size is within 2 millimeters, and your dizziness has the following possibilities.

1. Your pair of glasses have anisometropia in both eyes, so whether your last picture is also If there is a change, it may cause dizziness.

2. The interpupillary distance of your glasses is standard, and the pupil height is actually a little uncomfortable for ordinary people if the pupil height is more than a millimeter.

3. Is your frame horizontal on the table Is there a foot upturned 3. Maybe your refraction was not accurate at the beginning.

It is recommended that you go to another store to check the accuracy of the optometry and then determine whether the pupil height is standard (the national standard pupil height error is within the limit).

What is the horizontal distance between the optical centers of the new glasses? There is no horizontal deviation or mutual deviation exceeding the standard!

The change of interpupillary distance of glasses depends on the positioning of the optical center of the lens. Optical Center Generally speaking, it is the thinnest place of myopia lenses or the thickest place of farsightedness and presbyopia lenses, that is, when we wear glasses, the place where the line of sight passes, which is determined according to the interpupillary distance of each person.

The power of the lens is polished, the processing of the optical store is only the shape of the cutting size, this large lens is the original uncut, the optical shop only needs to cut the green oval part, so that the optical center of the spectacle lens is not the geometric center. In this way, the wearer can see things very comfortably, so the frame is immovable, and it is calibrated symmetrically before leaving the factory, because the determination of the optical center is not only based on the interpupillary distance, but also according to the size of the glasses frame and the geometric center of the glasses frame, which are marked on the glasses frame. Some materials are also not allowed to be changed, and the deformation is more serious.

I don't know if I understand your question correctly.

You can't adjust the glasses after they are fitted.

Only before doing it, it is necessary to make a suitable interpupillary distance according to the condition of the eyes, and after doing it, it cannot be adjusted, and it will not work if you adjust the lenses.

1. Definition of pupillary distance.

Papillary distance refers to the distance between the center of the pupils of the two eyes, or the distance between the centers of the pupils when the eyes are facing straight ahead and the eyes are parallel. It is generally represented by the English letter abbreviation "PD", and the unit is millimeters (mm).

When the pupils of both eyes are in a positive physiological state, the following two methods are usually used to measure.

1) The distance from the center point of the pupil of the right eye to the midpoint of the pupil of the left eye.

2) The distance from the outer edge of the pupil of the right eye (temporal side) to the inner edge of the pupil of the left eye (nasal side) or from the inner edge of the pupil of the right eye (nasal side) to the outer edge of the pupil of the left eye (temporal side).

Summary. Hello! There will be an impact, but not much. Inaccurate interpupillary distance can easily cause symptoms such as blurred vision, double vision, dizziness and discomfort.

Will it lead to an increase in power?

The impact of this adjustment is not very large.

The impact of this adjustment is not very large.

Interpupillary distance is very important for glasses, and it can directly affect the comfort of the patient wearing glasses. Wearing glasses with the wrong interpupillary distance for a long time will cause fatigue in the eyes, and the number of eyeballs will increase rapidly over time. In order to make the glasses more light and thin, the ulnar closure often increases the interpupillary distance, if you are worried about the impact, it is recommended to go to the hospital for refractive examination to measure the interpupillary distance when you are refracting glasses.

No matter how you change it, the interpupillary distance of the person.

It will not change, only the optical center distance of the glasses will change. The optical center distance changes unchanged, and the size of the old and new spectacle frames is the same. If the dimensions are the same, the optical center distance will not change; If there is a difference, there will be a change in the optical center distance.
