What is the difference between medical optometry and general optometry?

General optometry: It generally refers to the optometry in the optical store, which mainly refers to allowing people with refractive error to see objects clearly. The diopter is obtained according to computer refraction, and the operation methods and steps are relatively simple.

Medical optometry: Medical optometry is to check the aggregation of light after entering the eyeball, which is based on the state of the emmetropic eye to measure the degree of dispersion difference between the examined eye and the emmetropic eye.

2. The optometry process is different.

Ordinary optometry process: measurement of naked eye visual acuity - computer refraction - lens box test film method.

Medical optometry process: measurement of unaided eye visual acuity - computerized optometry - examination of the dominant eye - examination of eye position (strabismus, heterophoria) - examination of accommodative and fusion ability - examination of convergence and dilatation ability - pupil dilation or comprehensive optometry examination - audition - prescription.

3. The requirements for equipment personnel are different.

Medical optometry has high requirements for optometry equipment and personnel, and the quality of its completion is closely related to the professional knowledge of the operator. Qualified medical optometry should not only be able to see clearly, but also obtain a long-lasting and comfortable reading effect. Prescription of glasses is regarded as a strict medical practice in developed countries, and medical optometry must be performed before prescription of glasses.

Most ophthalmologists and hospitals rely only on computerized optometry and inserts for spectacle dispensing, which is also known as routine optometry. Modern optometry emphasizes the use of medical optometry for patients, and medical optometry must use a comprehensive refractor.

When a patient with myopia wears corrective lenses, corrected visual acuity can be achieved, at this time, and these 5 corrective lenses can achieve corrected visual acuity.

If you use conventional refraction, you can only choose one of these 5 corrective lenses as a prescription for refraction, which is arbitrary. However, in medical optometry, it has to choose only one fixed lens according to the examination results of the examinee's eye position, accommodation, binocular monovision and collection function, and even can be selected as the final prescription of optometry.

From this point of view, medical optometry and conventional optometry have different meanings and contents. From a medical point of view, the purpose of wearing corrective glasses is not only to make patients see objects clearly, but also to make them comfortable to wear glasses, and can ** some possible eye diseases, such as visual fatigue, esotropia or exotropia, etc., and medical optometry is the basis.

The content of medical optometry includes the prescription of optometry, eye position, accommodative power, binocular monovision function, convergence function, binocular adjustment balance, identification of the main eye, and finally a scientific optometry prescription is issued based on the above conditions, so as to achieve the purpose of wearing glasses clearly, comfortably, beautifully and healthily.

In view of the various myopia methods on the market, it is recommended that parents should be cautious, do not listen to biased beliefs, choose a regular hospital for optometry, timely prescription glasses or orthokeratology lenses, and go to the hospital for a re-examination every six months.

Conventional optometry pays more attention to the improvement of visual acuity, mainly inserts, objective silhouettes, and computerized refraction, and maximizes the corrected visual acuity through optical methods, but ignores the evaluation of binocular visual function. Compared with conventional optometry glasses, medical optometry glasses have the characteristics of accuracy, science, safety and reliability, which can protect the visual health of the human eye to the greatest extent. Children's refractive error is not a single computer refraction can be solved, it is necessary to scientifically distinguish between true and pseudomyopia, in order to prevent the real from being confused, and it is also necessary to differential diagnose whether there are problems such as amblyopia, strabismus, and abnormal visual function.

Our routine examination items include ocular alignment, ocular axis, curvature, slit lamp, fundus, etc. We pay attention to eye health and improve the quality of vision, so that children can see clearly, comfortably, and long-lasting, and only after a comprehensive examination can we customize a personalized correction plan according to the child's eye condition.

Ordinary conventional optometry, its purpose is only to let the refractive error see the object clearly, the examination method and equipment are relatively simple, just the process of refraction, computer refraction to obtain the diopter, and then try on lenses.

The main difference between medical vision and optical store vision is that optical store optometry only improves eyesight, simple inserts, and medical optometry is to check the eye condition and the correction of the eye.

If you have blurred vision, you need to go to the hospital for a formal medical optometry. There is an essential difference between medical optometry and optometry in an optician shop, which can only perform routine optometry because it has no medical qualifications. The purpose is only to allow patients with refractive errors to see objects clearly, and the examination methods and optometry equipment are relatively simple.

Hospital optometry is medical optometry, which is relatively complex and has high requirements for optometrists and optometry equipment.

Glasses are simple optical devices made to correct vision or protect the eyes, consisting of lenses and frames. Spectacles were invented in Italy at the end of the 13th century. At that time, the glasses could only be said to be magnifying glasses, and they were only held in their hands when they were reading.

A pair of spectacle frames is usually composed of the main parts such as the rim, nose pad, stump head and temples, in addition to the above parts, there are also foot covers, leaf support screws, hinge screws, etc.

Exercise and move your eyes properly. After staring at electronic products for a long time, the lens and other tissue structures in the eye area will be in a posture for a long time, and activities such as jogging or looking into the distance can be appropriately carried out, which will play a certain role in regulating the lens and reduce the impact on the eye area.

To open a brand glasses franchise store, you should be familiar with the local market environment and consumer demand, and then choose a good glasses brand, and choose a professional team to develop it, so that the reputation and quality are guaranteed.

Optometry is not an ordinary commercial operation, but a strict medical practice. Medical optometry is the premise of correct glasses, and it is essentially different from ordinary optometry: ordinary conventional optometry cannot determine the cause of poor vision, and medical optometry can rely on ophthalmologist examination to rule out other eye diseases that affect vision.

What is the difference between optometry in a hospital with glasses and optometry in an optician store?

In addition to medical optometry, the hospital will also conduct a comprehensive eye function examination, and then prescribe a reasonable and personalized prescription for glasses based on the results of visual function assessment and refractive status.

Different examinations: In the optical store, the visual acuity data detected by the comprehensive optometry instrument cannot be directly used as the prescription of the glasses, but also through a series of refraction procedures, such as insert refraction, try-on, etc. In the hospital, glasses are dispensed, that is, the visual power is measured with an optometry instrument in the ophthalmology department, and then the glasses are directly dispensed with the detected data.

In addition, there is an additional eye disease examination in the optometry section.

In this way, people will not feel deformed and dizzy when they wear glasses, which is also the best for protecting their eyes and vision, and in order to do word-of-mouth and gain more customers, the optical store will do it personally in the entire glasses process, which is conducive to glasses.

Precautions for wearing glasses:

If the patient's vision is poor, the first thing to do is to determine whether the patient has refractive error through dilated refraction, which is the refraction of parallel light rays through the refractive system of the eye, and the focus cannot be located in the fovea of the macula, which is called refractive error. If the patient's unaided visual acuity reaches a normal level after pupil dilation, he or she has pseudomyopia and does not require glasses**.

If the vision is still abnormal after the pupil is dilated, it will be necessary to wear glasses**. When wearing glasses, the first thing to do is to dilate the pupil refraction, paralyze the ciliary muscle to exclude true myopia and pseudomyopia, and the next day to re-test, on the basis of the initial test for fine-tuning, so that you can get an accurate refractive power, and try on glasses according to the diopter.

To open a glasses franchise store, you must choose a strong brand, and the franchise can be guaranteed, so that entrepreneurs can rest assured, and at the same time, the power of opening a store will be high.

In addition to helping to improve vision, the right glasses can also reduce the burden on the eyes and prevent further progression. Medical optometry is roughly divided into the following steps:1

Optometry is divided into comprehensive refraction, artificial silhouette and computer refraction, but for adolescents and children, the general recommendation is refraction after dilation, which can eliminate the interference of adjustment and accurately check the refractive power. 2.Re-examination: After trying on the lenses through optometry, a re-examination is carried out to improve the vision by adjusting and determining the prescription of the glasses.

3 Accurate measurement of interpupillary distance The distance between the center of the pupils of the two eyes is called interpupillary distance, and the optical center of the lens and the line of sight should be consistent with the spectacle lens to avoid dizziness and fatigue. Therefore, through standardized refraction, professional power design, correct interpupillary distance measurement, and sufficient try-on adjustment, you can get a pair of qualified glasses.

Professional medical "optometry glasses" is a complex medical process, glasses is a medical tool to correct refractive diseases, by no means a universal commodity, accurate, durable, comfortable, beautiful is the standard to evaluate the quality of glasses. The content of medical optometry includes the prescription of optometry, eye position, accommodative power, binocular monovision function, convergence function, binocular adjustment balance, and the identification of the dominant eye, and finally a scientific optometry prescription is issued based on the above conditions, so as to achieve the purpose of wearing glasses clearly, comfortably, beautifully and healthily care, and at the same time, the medical technology of non-surgical correction of refractive error and correction of strabismus has reached a high level.

The difference between general optometry and medical optometry is mainly in the following three aspects:

First, the standard of optometry is different

General optometry. According to the computer refraction data, the rapid dispensing of glasses, the examination methods and equipment are relatively simple; Its purpose is only to allow the refractive person to see clearly; Individual optometrists do not have basic knowledge of ophthalmology, so they work directly in the optical store after short-term training;

Medical optometry must be examined in accordance with a rigorous medical optometry procedure; Determine the truth or falsity of the patient's myopia; Check for eye diseases such as strabismus and amblyopia;

control diopter development, improve visual quality, and alleviate eye fatigue; Finally, a scientific optometry prescription is issued to achieve the purpose of wearing glasses clearly, comfortably, beautifully and healthily;

Second, the optometry equipment is different

Ordinary optometry eye chart, automatic computer refractor, comprehensive refractor, ophthalmoscope, etc.;

In addition to the above-mentioned conventional optometry equipment, medical optometry also has professional equipment such as isovisual machines, slit lamps, and visual function detectors. The main functions of these professional optometry devices are: to check for refractive errors; Check binocular visual development and extraocular muscle function; timely detection of ocular pathological changes;

3. The optometry process is different

general optometry naked-eye visual acuity;

computerized optometry; Optometry lens box test film (commonly known as insert refraction).

In addition to the routine optometry process, medical optometry includes: eye health related examinations (to rule out various eye diseases); Objective examination, dilated pupil examination (distinguishing between true and false myopia); foggy vision, ocular vision, spectacled vision, and aperture vision; Binocular accommodative test (to determine the degree to which the binocular vision cooperates); color vision, ultrasound and other examinations (early detection of ocular pathological changes);

Ordinary conventional optometry, its purpose is only to let the refractive error see the object clearly, the examination method and equipment are relatively simple, just the process of refraction and computer refraction, and then try on lenses, which is also the process adopted by most optical stores.

Lincang Aiwei Ophthalmic Medical Optometry and Ordinary Conventional Optometry are two completely different optometry methods, the formal medical optometry steps are rigorous, and its purpose is to match glasses according to the comprehensive function of the human eye, and its effect is significantly better than that of ordinary optometry. As a medical act, medical optometry must be performed to ensure accurate glasses and a pair of glasses that are both comfortable and can play a role in health care.

Medical optometry is actually dilated refraction, the purpose of dilated pupils is to distinguish pseudomyopia, generally for children under 12 years old, if it is the first time to wear glasses, then dilated refraction, but if you have worn glasses, there is no need for dilated pupils.

Hello, medical optometry adds dilated pupil and fundus examination to the general optometry. If you are an adult with glasses, you only need ordinary optometry.

If you have myopia or presbyopia at the same time, you still need to wear myopia glasses or reading glasses after surgery, while Dalian Aier Eye Hospital Huanjing cataract surgery, these eye problems can be solved in one operation.

Dalian Aier Eye Hospital's rejuvenating cataract surgery removes the patient's old intraocular lens, which has been clouded, and then implants a new trifocal lens to restore far, medium and near vision. Compared with other intraocular lenses, trifocal lenses can have clear long-distance vision, near vision and medium-distance vision at the same time, whether it is reading, reading newspapers, writing, playing with mobile phones at close range, watching TV, driving, or watching scenery from a long distance, all scenarios can be completed.

Well, hello! 30 astigmatism, there should be no such thing, or 25, or 50, but under normal circumstances, 25 astigmatism can be directly ignored, 50 astigmatism, depending on the situation, sometimes you can ignore it, but, look at you, after getting a 200 astigmatism, glasses used for a year, and now dilated pupils to look down, only 30 (let's take it as 30), in this way, because you have been using a pair of glasses that do not fit before, but due to a long time, you have slowly adapted, On the contrary, you can't adapt to the lens under the correct data, in this case, we can only try to get closer to the previous 200 and find an optimal power between 30 and 200 for you to use.

Pupil dilation is especially important, please confirm whether the place you go to has this qualification before dilating your pupils, otherwise it may affect your life!

Hope mine can help you!
