What Does an Optometric Physician Do?
Professional medical "optometry" is a complicated medical process. Glasses are a medical tool for correcting refractive diseases. They are by no means a universal commodity. Accuracy, durability, comfort and aesthetics are the criteria for evaluating the quality of optics. The content of medical optometry includes the power of optometry, eye position, adjustment power, binocular monocular function, convergence convergence function, binocular adjustment balance, discrimination of the dominant eye, and finally a scientific optometry prescription is formulated based on the above-mentioned conditions to achieve clear wearing glasses. , Comfort, aesthetics and health care, while making non-surgical correction of refractive error, correction of strabismus and other medical technologies have reached a high level.
Medical optometry
- Professional medical "optometry" is a complicated medical process. Glasses are a medical tool for correcting refractive diseases. They are by no means a universal commodity. Accuracy, durability, comfort and aesthetics are the criteria for evaluating the quality of optics. The content of medical optometry includes the degree of optometry, eye position,
- Myopia is the parallel light that passes through the eye without adjustment.
- Medical optometry is a dynamic, multi-procedure clinical diagnostic process. The first is that the optometrist should understand the patient's medical history, general eye conditions and general conditions of the whole body. Therefore, it must be operated by a professional optometrist, and one of the most suitable prescriptions should be selected. Glasses are not a commodity. Nearsightedness, farsightedness,
- The optical center of the lens and the interpupillary distance must be basically the same. If the difference is large, the effect of the triangular prism can be produced. The greater the refractive power, the greater the effect of the triangular prism, which is often difficult for patients to tolerate.
- Glasses tilt: 10 to 15 degrees to the forehead
- Lens--appropriate eye distance (the lens should be placed at the tip of the cornea 12 mm, that is, the front main focal point of the eye. If the lens is placed too far or too close, both the negative and positive lenses' refractive power can be increased or weakened. The difference in the size of the imaging on the retina of the two eyes, the higher the power of the lens, the greater the difference. If the lenses of the two eyes are not at the same distance or tilted, the lens itself can also cause
- Medical optometry has first-class inspection equipment and inspection methods, equipped with imported comprehensive optometry, slit lamp, direct ophthalmoscope, direct optometry, applanation tonometer, computer optometry, non-contact tonometer, corneal topography Picture measuring instrument, visual function tester, MTI visual screener, children's VEP tester, synoptic machine, and equipped with the latest opto-optical instruments such as automatic edger. Relying on the hospital's ophthalmology medical technology, not only has rich clinical experience in ordinary refractive corrections, but also special refractive corrections, especially difficult diopter frame glasses, corneal orthopedics to control the deepening of children's myopia, RGP with high safety and breathability, progressive films for teenagers, anti-fatigue mirrors, and progressive multifocal lenses preferred by presbyopia are all unique in the province. In the province, the advanced concepts of medical optometry and medical optics were first put forward, and the standardized procedure for optometry clinics was first developed.
- Misunderstanding 1: "Computer optics are very advanced, and youth opticians are very simple."
- The computer optometry commonly used in optical shops is a type of objective optometry. The speed is faster, and most of them can judge the refractive properties more accurately. However, the result cannot be used as an accurate prescription for optician. The number displayed each time the button is pressed may be different. Especially for the optometry of adolescents, it is necessary to determine whether there is false myopia. If false myopia is treated as true myopia, it will be false.
- The child's hyperopia, high astigmatism can also make the computer feel "inadequate" when checking. More terrible are amblyopia, strabismus, congenital cataract, congenital glaucoma, congenital fundus disease, congenital nystagmus and other eye diseases are also the cause of vision loss. If you do not have regular eye examination, it is likely to be misdiagnosed as myopia, missed The best time to treat is difficult to make up for life.
- Misunderstanding 2: "Youth opticians should choose more expensive"
- The most important prerequisite for students to choose glasses is to suit themselves. Don't blindly pursue fashion to choose frameless or perforated frames. Children under the age of 10 can choose glasses frames with soft edges and protective nose pads when they are paired with glasses.
- Children should first consider the use of resin-hardened spectacle lenses when choosing lenses. Glass lenses are fragile and easily cause damage to children's eyes. Resin lenses mainly require accurate astigmatism axis position, the photometric must be accurate, there must be no scratches on the lens, there must be no bubbles and impurities, the prescription of children's spectacle lenses must meet the quality inspection standards issued by the state. The error of the diopter should be within the requirements of the nationally issued standards.
- Misunderstanding 3: "Adolescents are not suitable for wearing contact lenses"
- Teenagers are not suitable for wearing contact lenses. They are worried that contact lenses may damage their eyes. It is true that ordinary soft contact lenses are not recommended for adolescents, but there are two types of hard contact lenses that have obvious effects on controlling the development of myopia in adolescents, but many ophthalmologists recommend wearing them.
- The first type: RGP contact lens. It has a high oxygen permeability, which can ensure sufficient nutrients and can ensure the health of the cornea of the eye; at the same time, it has strong hardness and good optical properties, good visual quality, and is not easy to feel visual fatigue. It also has a certain role in controlling the development of myopia in adolescents. It has been widely used and affirmed in developed countries such as Japan, Europe and the United States. The Ministry of Health of China has designated RGP contact lenses as the only ophthalmology promotion project of the National "Ten Decades Project".
- The second type: MCT orthokeratology lens. It can correct vision to normal or near normal for those with mild or moderate myopia (less than 600 degrees). My eyesight can be significantly reduced after trying for 2-4 hours; in a few weeks or even a few days, the naked eye vision can be significantly improved; just wear 8-10 hours at night, you can easily get clear vision during the day; Protect adolescents' vision, control the rapid progression of myopia, and avoid continuous deterioration of vision.
- What is called the scientific optician?
- Myopia is of course not my own wish, but apart from hereditary factors, most of myopia is due to acquired problems, unreasonable use of the eyes, carelessness when the eyes are uncomfortable, etc. The most direct correction method is to wear glasses.
- Myopia is increasing. Many people go to the eyeglasses on the street to buy a pair of eyes to wear when they have vision loss, or borrow the glasses of their classmates. Regardless of their degree, these practices are actually wrong. , Will further aggravate myopia, here to remind people with myopia to scientific glasses, protect their eyes.
- Scientific opticians do this: Optometry is the most important of all the procedures of opticians, and we must pursue precision, and the error should be kept within plus or minus 50 degrees. Inaccurate spectacles can lead to overcorrection or undercorrection of vision, which can cause eye swelling and visual fatigue that increase the burden on the eyes.
- Interpupillary distance should be clear. People's eyes are the same as those of their hands. They have one dominant eye. When the power of the two eyes is different, it is important to measure the interpupillary distance and maintain the balance of the eyes. It is important to coordinate the dominant eye and the non-dominant eye, otherwise you are looking Time will lose weight.
- Don't blindly pursue quick glasses. One-sided emphasis is fast, which will inevitably reduce the requirements for the quality of glasses.
- Contact lenses are divided into soft lenses and hard lenses. A soft lens refers to a general water-containing soft lens, which is characterized by fast adaptation, comfortable wearing, good stability, and frequent replacement. The hard lens optical correction effect is significantly better than the soft lens and frame glasses. It is not sold in major eyeglass stores in the city. Patients with myopia can go to the hospital to measure the degree and corneal arc, and then let the hospital send the materials to the manufacturer for "customizing the eye .
- The size of the frame is exquisite, and the upper edge of the frame should be parallel to the eyebrows. In this way, it will not affect the field of vision. Don't blindly pursue small frames, you must decide according to your face shape.
- Go to the hospital or optician shop at least once every six months to check the power after myopia, so that the power is completely stable.
