The treatment of myopia can be categorized into surgical and non-surgical therapies (1) The best treatment for myopia – wearing a pair of suitable glasses. Myopic patients have different degrees of reduction in distance vision, see a few meters away from the scene hazy, go to the shopping mall, can not see the display of goods and price tags; walking on the road, can not identify acquaintances walking across the street, do not greet people, was considered to be a pose and ignoring people; students see the wrong blackboard exercises, do the wrong homework. All these things make myopic people suffer a lot. To get out of this hazy world, the only way is to wear glasses. However, there are some patients suffering from myopia, would rather not be able to see things in the distance, squinting and anxious, but also not willing to wear glasses. The reason is that it is inconvenient for young people to wear glasses, and they are afraid of touching and falling. Some people also think that wearing glasses is unattractive and hinders their appearance. They are afraid that the more glasses they wear, the deeper their prescription becomes, and they will not be able to take off their glasses after they have been put on, so they put their glasses in their pockets and only wear them when they look at a faraway place. In fact, this is not correct. When you are nearsighted, you cannot see distant objects because the parallel light rays entering your eyes cannot be focused on the retina. Although it is clearer to see things at a close distance, it is easy to cause eye fatigue when your eyes are too close to the books when you are studying. Children with myopia, performance is not lively, on the subject of attention is not focused, can not see the blackboard learning performance decline, and sometimes can produce strabismus. If you wear a pair of appropriate myopia glasses, you can move the image in front of the retina backward, so that it falls exactly on the retina, so you can immediately see things clearly. This will bring great convenience to both work and study, so why not? As for wearing glasses is inconvenient and unattractive, these concerns should be dispelled, wearing glasses is to correct vision defects, reduce eye fatigue, wear some days to get used to it, there is nothing unattractive. Will myopia get deeper after wearing glasses? We say generally no. The development of myopia has nothing to do with wearing glasses. It is true that some people with myopia, since wearing glasses after a period of time myopia deepened, and have to re-open the optometry, this is why? Some people think everything is fine after glasses, writing or reading books, still very close, do not pay attention to vision hygiene, reading time is too long, or lying down to read books or walk to read books or read books in places with insufficient lighting, etc., for a long time, the same lead to visual fatigue, myopia is increasing. Some young people take wearing glasses as a kind of burden, wear them for a while, don’t wear them for a while, wear them when they are happy, don’t wear them when they are not happy, or wear them when they look at the distance only, so that their eyes are often in an unstable state of adjustment, which will also make myopia deepen gradually. Some people do not go through dilated optometry or the optometrist is not experienced enough to make the glasses not suitable. Some people just buy a pair of glasses in the store or take other people’s glasses to wear, even after wearing a mirror sometimes can barely see, but can not last, a long time the eyes will feel sore and uncomfortable. Not only can not improve vision, but will make myopia deepen. Therefore, myopic people, must go to the hospital dilated optometry or ask experienced optometrist optometry, with a pair of appropriate glasses, in addition to sleep and wash your face, all day and night to wear. Remember to never blindly borrow someone else’s glasses. How can I get an accurate and comfortable pair of glasses? Teenagers suffering from myopia must go to the hospital to have their vision checked and have their eyesight dilated. Pupil dilation optometry, also known as objective optometry, is the application of drugs (such as 2% after Matropine, 1% atropine eye drops, etc.), so that the ciliary muscle is completely paralyzed, the pupil dilated, the loss of regulation of the situation for optometry. In this way, the refractive state of the eye is determined objectively and accurately by eliminating the interfering influence of accommodation and the pseudomyopia caused by it. Then, the eyeglass lenses are sharpened according to the eyeglass prescription determined by the eyeglass examination, and the sharpened lenses are mounted on the eyeglass frames that have been selected in advance. Usually, a retest is conducted at a certain time after the dilated eye examination. Observe whether the refractive power of the lenses tested by the objective optometry has any abnormal discomfort such as dizziness, nausea, blurred vision, distorted vision, or unsteady walking. Through retesting, organically combining the objective results of dilated optometry with the subjective results of post-testing in a consistent manner to maximize the high quality of eyeglasses fitting, so as to achieve the effect of the best correction of visual acuity. Some young people are not willing to dilate the pupil optical examination, afraid of dilating the pupil after the eye is uncomfortable, can not see the near things. In fact, this worry is superfluous. Pharmacology pupil dilation optometry drugs used (such as atropine, post-matropine, etc.) for the anticholinergic drugs. Its role in the pupil dilation muscle and ciliary muscle paralysis and relaxation, manifested as pupil dilation and regulation of paralysis, the role of this drug is only temporary, as long as no longer continue to use, after a certain period of time, the paralytic effect of the drug will disappear naturally. If you don’t use dilated optometry, due to the ciliary muscle, lens regulation, may be tested too large or false myopia results, so, young myopia should be dilated optometry, selection of appropriate myopia glasses. Only when the following conditions exist: (1) Examination found shallow anterior chamber, high intraocular pressure or the high limit of normal value, suspected glaucoma patients, should wait for a detailed history, a clear diagnosis before optometry. The application of dilated optometry is absolutely contraindicated in patients with glaucoma. (2) Severe lens, vitreous clouding, corneal white spots, due to the difficulty of examination, dilated optometry is meaningless. (3) Severe pupil adhesion, the pupil can not be normally dilated after the application of dilating drugs, there is no need to dilate the pupil optometry. (4) People over 40 years of age, due to the weakening of ciliary muscle regulation, generally no longer dilated optometry. At present, the main material for making spectacle lenses is optical glass, also called optical spectacle lenses. In addition, there are optical resin eyeglass lenses. Optical glass has the following advantages (1) high light transmittance light transmittance of up to 92%, if the surface of the lens is coated with one or more layers of magnesium fluoride to increase the transmittance of the film, the light transmittance of the lens can reach 99.2%. (2)Absorb ultraviolet rays Avoid ultraviolet damage to eyes. (3)Chemical stability Resistant to corrosion by acid, alkali and other chemicals. (4)Constant and accurate refractive index The refractive index is 1.523, constant and accurate, and the refractive index is accurate after processing. Optical resin is characterized by light weight, hardness close to glass, refractive index of 1.490, the new high refractive index thermosetting resin refractive index of 1.600, the surface is coated with a super-hard film and non-reflective multilayer film to enhance wear resistance, light transmittance of up to 98% and can block ultraviolet rays. Ground by the optical resin spectacle lenses, not easy to break damage to the eyeballs, security, has been widely used. Crystal material hard wear-resistant adiabatic good, but the ultraviolet absorption performance is worse than optical glass, light transmittance is also poor, is not the production of spectacle lenses of the ideal material, not to mention the good quality of eye care. Spectacle lenses layer luminosity processing must be precise, grinding into the mirror to be consistent with the prescription, the error of the refractive error should not exceed 0.04d-0.09d of the Ministry of Light Industry, the Ministry of the standard. The distance between the optical centers of the two spectacle lenses and the distance between the pupils of the two eyes should also be consistent. What we see and wear everyday are glasses that are set on the bridge of the nose or clamped on the ears, which is very inconvenient. There are also people who have a large degree of myopia in one eye and a small degree of myopia in the other eye, or have cataract surgery in one eye and a normal eye in the other. Due to the refractive error of the two eyes is too large, one eye to see something big, the other eye to see something too small, the visual center can not blend them together, therefore, ordinary glasses can not be worn. In recent years, a type of eyeglasses that are worn but not visible, commonly known as contact lenses, has emerged. It is a lens that is worn directly on the surface of the tear layer of the cornea, and between the cornea and the lens there exists a liquid lens composed of tears. In this way, a new refractive system is formed by the lens, the liquid lens, the cornea and other refractive interstitium of the eye. In medicine, this is called a corneal contact lens. Contact lenses can be categorized into hard and soft contact lenses depending on the material of the lens. Hard contact lenses are made of methyl methacrylate-based Plexiglas, which is hard and not easily deformed. They are suitable for correcting high astigmatism and conical cornea. Its disadvantage is that it is not breathable, cannot permeate oxygen, carbon dioxide, water and metabolic substances, and is not very comfortable to wear. Soft contact lenses are made of hydroxyacetic acid methacrylate or silicone rubber, which are soft, breathable, and can absorb water, so they are soft and comfortable to wear and can be used to treat keratoconus, but they are easy to change shape and are not suitable for astigmatic eyes. According to the way of wearing, there are long wearing type and daily wearing type. Contact lenses that are worn overnight for more than two consecutive days are long-wearing, including weekly, monthly and even no-detachment types. Long-wearing lenses are worn for many days before being removed and cleaned once. Tear fluid proteins and other substances are deposited on the lenses, and permanent cloudy spots eventually occur, affecting the clarity of the lenses. More serious is the breeding of bacteria, it is very easy to occur infectious keratitis, in view of this, at present, the long wearing way is not advocated. The daily wear type should be worn continuously for no more than 14 hours, and must be removed each night for necessary cleaning, disinfection and proper storage, and then worn again on the same day. Because the lenses are removed nightly for cleaning in the daily wear mode, the lenses will not develop permanent cloudy spots. With daily cleaning and disinfection, the likelihood of infectious keratitis is greatly reduced. Therefore, daily wear must be adhered to and long wear is not advisable. Contact lenses have advantages that ordinary glasses do not have and solve problems that ordinary glasses cannot solve. Since contact lenses are closely adsorbed with the cornea and can be rotated with the rotation of the eyeball, no matter which direction the eyeball turns to, the light always enters the eye through the center of the lens, which eliminates the defects of prismatic effect and oblique astigmatism produced by the rim of ordinary eyeglasses. Contact lenses are ground according to the patient’s corneal surface curvature and refractive index, it is tightly attached to the cornea, so that the lens, the tear layer and the cornea form a new refractive interstitial, involved in the composition of a complete optical unit, the curvature of the surface of the lens can be arbitrarily ground according to the refractive requirements. It replaces the irregular curvature of the corneal surface, effectively eliminates corneal irregular astigmatism, and reduces the disparity in the size of the object image between the two eyes. As contact lenses are close to the cornea, the distance from the center of the eyeball is shortened, and after the light passes through, the image formed on the retina is more or less the same as when you don’t wear lenses, and you won’t magnify or reduce the size of the object when you look at it. It avoids the shortcomings of ordinary glasses and is most suitable for people with large refractive error in both eyes or people without crystal in one eye. Contact lenses are thin and light, adsorbed on the surface of the cornea, which is much more convenient than the thick and heavy lenses of high myopia glasses. In addition, they are very convenient for people with special needs (e.g. actors, athletes). It is because contact lenses have so many advantages that ordinary glasses do not have, so its application range is much wider than ordinary glasses. Contact lenses are more suitable for the following cases: (1) High myopia, refractive error of more than 3.00d in both eyes, mixed corneal astigmatism or irregular astigmatism. Especially some literary or sports workers, due to the needs of the profession, wearing ordinary glasses will affect the work or competition results, can choose to use contact lenses. (2) Some people who have had cataract surgery on one eye can only wear contact lenses because the refractive error is too large to wear ordinary glasses. (3) Soft contact lenses can be used to treat corneal edema, exposure keratitis, and dry keratoconjunctivitis. Coating the periphery of the lens with the same color as the iris and keeping the central part transparent can eliminate the photophobic symptoms of albino patients and patients with iris defects. In recent years, there are also specially made for therapeutic purposes and corneal contact lenses, contact lenses soaked with a certain drug, can be released to the conjunctival sac at regular intervals, which not only reduces the number of times the drug is dispensed and saves the amount of the drug, at the same time, it can make the conjunctival sac always maintain a higher concentration of the drug, to achieve better therapeutic effects, such as the treatment of glaucoma, corneal ulcers, and so on. Although contact lenses have many advantages, however, they also have certain limitations, not everyone is suitable for wearing.
