Do you know how to fit a pair of glasses that suits you?

What is medical optometry? Medical optometry is based on the medical theory of optometry and is done by an optometrist in two steps. The first step is a thorough examination of the eye to rule out eye diseases other than refractive error. The second step is to use special equipment such as comprehensive optometry to accurately determine the refractive state and visual function of both eyes from both subjective and objective aspects on the basis of normal eye examination. What is the difference between professional medical optometry and general optometry? If you have bad eyesight, you think you can go to an optician to get glasses, but you don’t know that there are many things to learn about glasses. It is not scientific enough to give students glasses based only on the degree of computerized or manual optometry. The result is simply that the refractive error can be seen more clearly, and it is very easy to see fatigue and further deepening of the lens prescription. Medical optometry is not only based on the results of optometry to determine the number of glasses, but by the ophthalmologist for eye examination, and then according to the student’s age, eye position, eye adjustment ability, the coordination function of both eyes, and the impact of disease on refraction and other comprehensive factors. After wearing glasses, the student will have to be reviewed periodically to adjust the prescription or determine whether to continue wearing glasses, which requires the use of medical optometry to make timely adjustments. Will myopia increase with glasses? The conventional treatment for myopia is to wear a proper pair of glasses. People who have myopia can get clear images with myopia glasses, so that their vision can be corrected. But there are some people who suffer from myopia and would rather not be able to see things in the distance, squinting and anxious, rather than wear glasses. Fear of wearing glasses after the degree will deepen, put on the don’t want to take off, with a good glasses in the pocket, only when looking at the distance to wear. In fact, this is not the right way to think. If you wear the right pair of myopic glasses, you can move the image in front of the retina backwards so that it falls right on the retina and you can see clearly right away. This will be very convenient for both work and study, so why not? As for the inconvenience of wearing glasses, these concerns should be dispelled, wear glasses is to correct vision defects, reduce eye fatigue, wear some days to get used to, and there is nothing unattractive. After wearing glasses, will myopia get deeper and deeper? We say that it will not. The development of myopia has nothing to do with wearing glasses. It is true that some myopic teenagers wear glasses for a period of time and then their myopia deepens and they have to get a new prescription, mainly because their eyes are developing and they have a heavy visual load. Some people still do not pay attention to eye hygiene after glasses, reading for too long, or lying down to read, or reading in places with insufficient lighting, over time, the same myopia deepened. Some people take wearing glasses as a burden, wear them for a while, or only wear them when looking at a distance, so that the eyes are often in an unstable state of adjustment, which will also gradually deepen the degree. Some people do not have accurate medical vision, just buy a pair in the mall or take other people’s glasses with them, the eyes feel sore and uncomfortable for a long time, not only vision can not improve, but the degree of deepening. Therefore, people with nearsightedness must ask an experienced optometrist for an accurate optometry and a suitable pair of glasses to wear all day and all night except for sleeping and washing their faces. How can I get a pair of accurate and comfortable glasses? If you are a teenager with myopia, you must go to a hospital to have your vision checked and your pupils dilated for optometry. This is also known as objective optometry, which is the application of drugs (such as 2% post-matropine, 1% atropine eye drops, etc.), so that the ciliary muscle is completely paralyzed, the pupil is dilated, and the adjustment is lost. In this way, the interfering effects of accommodation and the pseudomyopia caused by it are excluded, and the refractive state of the eye is determined objectively and accurately. The lenses are then sharpened according to the prescription determined by the optometrist, and the sharpened lenses are fitted to the pre-selected frame. Usually a retest is performed at a certain time after the dilated eye examination. The refractive power of the lenses tested by objective optometry is observed for abnormal discomfort such as dizziness, nausea, blurred vision, distortion of vision or unstable walking. Through retesting, the objective results of the dilated eye examination and the subjective results of the post-examination are organically combined to ensure the highest quality of eyeglass fitting and to achieve the best corrected vision. Some people are reluctant to have their eyes dilated for fear that they will be uncomfortable and unable to see near things. In fact, this fear is superfluous. Pharmacologically, the drugs used for dilated eye examinations are anticholinergics. The effect of these drugs is only temporary, and the paralyzing effect will disappear naturally after a certain period of time, as long as they are not used anymore. If you don’t use the medication, the ciliary muscle and the lens will adjust, and you may get an oversized or pseudomyopia result. How to choose the right glasses? The best choice is to choose lenses with low impurities, high transmittance and refractive index, and light weight, so that you can see clearly and feel comfortable. Poor quality lenses, easy to see fatigue, blurred vision, dizziness, etc., the same will bring harm to the health of the eyes. There are two kinds of optical eyeglass lenses and optical resin eyeglass lenses on the market, the choice is more optical resin lenses, it has a light weight, good impact resistance, especially some coated lenses also have high clarity, UV protection and other characteristics, especially for young people to choose, if the refractive index is high should choose high refractive index lenses. Do not choose lenses in the pursuit of cheap, cheap price as a criterion to choose lenses, often at the expense of the patients themselves. Good quality lenses have better refractive index and light transmission, some are also hardened (increased corrosion resistance), film, UV protection, and are good value for money. The quality of cheap lenses may not be guaranteed and can cause damage to the eyes after wearing them for a long time. The low number of lenses do not need to match ultra-thin, because the thinner the lens the more expensive but a waste of money. Choose frame: “suitable” frame in addition to price satisfaction, style like, more critical is the specification, size and their own face is appropriate for the width, to not pinch face as appropriate. Do not pursue a large frame, because the more brilliant lens fitter can not guarantee the lens optical center distance and pupil distance consistent, due to the optical center distance and pupil distance exceed the standard will produce prismatic effect, resulting in some discomfort wearers, serious will endanger the body and eye health. Therefore, we remind everyone to beware of counterfeit goods and false advertising, and suggest that patients in need should go to a professional eye care institution to receive medical optometry and treasure the health of their eyes.
