Abstract: medical optometry is not only the premise of matching a pair of effective, comfortable and healthy glasses, but also the direct embodiment of matching glasses as an important content of optometry. Ordinary routine optometry refers to the optometry with glasses in general optical shops. Its purpose is only to let the ametropic see the object clearly. The operation methods and steps are relatively simple. Medical optometry must first have a high-precision and high-cost comprehensive optometer, and then have strict requirements for optometrists. They must be optometrists who are familiar with clinical ophthalmology and optometry., Medical optometry is not only the premise of matching a pair of effective, comfortable and healthy glasses, but also the direct embodiment of matching glasses as an important content of optometry.

optometry is a rigorous medical and procedural process. We can’t just rely on computer optometry or insert a few lenses. We can simply check our eyesight for a few minutes to solve the problem. The time required for a set of scientific and standardized medical optometry is at least 20-30 minutes. Choosing medical optometry is the premise of effective matching. Especially for teenagers, computer optometry is likely to turn “false myopia” into “true myopia” because it is easy to “overcorrect”. Teenagers under the age of 18 are in the process of eye development. If they are short-sighted, they must have more than one to two medical optometry every year; If you have hyperopia, do it quickly at least every 6 months. Ten steps of medical optometry {1. Visual acuity examination: check the patient’s naked visual acuity with a visual acuity chart. Patients who have worn glasses should also wear the original glasses to check and correct their visual acuity. 2. Slit lamp microscopic examination. Slit lamp microscopic examination is to understand the basic situation of the front of the patient’s eyes and the characteristics of tear film, and to check whether the patient has eyelid entropion, trichiasis, conjunctivitis, keratitis, dry eye, cataract and other eye diseases. 3. Intraocular pressure test: the doctor checks the patient’s intraocular pressure with a non-contact tonometer to screen for eye diseases such as glaucoma, retinal detachment or retinitis pigmentosa. 4. Vitreous body examination and fundus camera examination of fundus, to understand the basic condition of vitreous body and retina, to know whether patients suffer from vitreous opacity, retinal arteriosclerosis, optic neuropathy, retinitis, whether there is high myopia, diabetes, hypertensive retinopathy, senile macular degeneration, etc. If the patient’s eyes are found to be abnormal in the above examinations, the doctor will further conduct detailed ophthalmic examination, carry out corresponding treatment, and then consider matching glasses. 5. Computer optometry and corneal curvature measurement. Through these two examinations, we can understand the basic situation of the refractive state of both eyes, measure the refractive indexes such as myopia, hyperopia, astigmatism and astigmatism axis, as well as the radius of curvature, corneal astigmatism value and astigmatism axis of the two intersecting radial lines of the cornea. When necessary, the doctor should perform mydriatic optometry on the patient. 6. Synoptophore, corneal refraction and stereopsis. Corneal refraction, stereopsis or synoptophore examination shall be carried out as required. Generally, patients with strabismus, amblyopia and abnormal binocular visual function, especially children’s first diagnosis, need this examination. 7. In optometry, the pupil distance of both eyes of the patient shall be measured first, and then the diopter and visual function of both eyes shall be further effectively measured through retinoscopy and comprehensive optometry, such as radiance function, whether there is cryptotropia and binocular visual balance. If you are a presbyopia patient, you should also measure the adjustment force to determine the degree of presbyopia. 8. Color vision examination: according to the patient’s situation, color vision examination is to use the color vision examination chart to check whether the patient has color blindness and color weakness, and make qualitative and semi quantitative analysis on the abnormal color vision. 9. Try on glasses. The doctor selects the corresponding try on frame according to the distance between the pupils of both eyes of the patient; Then, according to the analysis of the above examination results, select the appropriate lens to be inserted into the audition frame, and let the patient try on for about 30 minutes. If the vision reaches a better state and the patient does not feel uncomfortable, this data can be used as a prescription for glasses. 10. After selecting the lens frame and testing, it is to select the lens frame and lens. The selection of frames and lenses with the assistance of professionals can not only meet the patients’ wishes for style design, materials and price, but also meet the requirements of prescription and processing. The prepared glasses also need to be tested and verified by the following instruments, so that the patients can get qualified glasses.
