Abstract: rigid breathable contact lenses are made of high permeability polymer materials, which are characterized by high clarity, high oxygen permeability, anti precipitation, less pollution and high strength. Compared with ordinary soft contact lenses, its optical imaging quality is superior., Ametropia is the most common cause of vision loss in adolescents, among which myopia, hyperopia and astigmatism are the most common. In particular, the prevalence of myopia is increasing year by year. The correction methods of ametropia mainly include surgical methods and non-surgical methods. Adolescent patients under the age of 18 can not accept surgical treatment. They can only choose non-surgical methods such as frame glasses, contact lenses, drugs and some physical therapy., Frame glasses can effectively correct vision, but it has no obvious effect on the treatment and control of ametropia. In addition, the correction effect of frame glasses on anisometropia (diopter difference between two eyes is more than 2.50d) and irregular astigmatism is not ideal. Rigid breathable contact lenses (RGPCL) can be considered for adolescent patients under the age of 18 (RGPCL) to correct vision, which is more effective than frame glasses. Hard breathable contact lenses are made of high breathable polymer materials, which are characterized by high clarity, high oxygen permeability, anti precipitation, less pollution and high strength. Compared with ordinary soft contact lenses, they have superior optical imaging quality, and long-term wearing glasses has no significant impact on corneal physiological metabolism, so they are safe It not only has good correction effect on juvenile myopia, but also has a certain role in controlling the development of myopia. Its effect has been clinically verified at home and abroad: good formability can give full play to the effect of tear lens to correct all kinds of astigmatism, especially medium and high astigmatism and irregular astigmatism; It can be specially designed and processed, and has a good corrective effect on patients with congenital abnormalities, keratoconus, eye trauma, high corneal deformation after operation and so on., Corneal orthosis, another promising contact lens, is a specially designed RGPCL. Through reasonable physical correction of the cornea, it can quickly reduce the degree of myopia and significantly improve the naked vision of medium and low myopia. Most importantly, it can effectively control the growth of myopia. It has obvious effect and exact effect. It is especially suitable for adolescent myopia patients with rapid development of myopia. At present, this technology has attracted high attention from experts at home and abroad. It should be noted that corneal orthosis is a medical product, which requires high fitting technology and good supporting medical equipment. Fitting must be carried out under the strict supervision and guidance of ophthalmologists or optometrists in order to ensure its safety. Moreover, to maintain good control effect, it is necessary to wear glasses for observation for a long time.,

frame glasses
frame glasses can effectively correct vision, but they have no obvious effect on the treatment and control of ametropia. In addition, the correction effect of frame glasses on anisometropia (diopter difference of more than 2.50d) and irregular astigmatism is not ideal.
rigid breathable contact lenses (RGPCL)
rigid breathable contact lenses can be considered for young patients under the age of 18 (RGPCL) to correct vision, which is more effective than frame glasses. Hard breathable contact lenses are made of high breathable polymer materials, which are characterized by high clarity, high oxygen permeability, anti precipitation, less pollution and high strength. Compared with ordinary soft contact lenses, they have superior optical imaging quality, and long-term wearing glasses has no significant impact on corneal physiological metabolism, so they are safe It not only has good correction effect on juvenile myopia, but also has a certain role in controlling the development of myopia. Its effect has been clinically verified at home and abroad: good formability can give full play to the effect of tear lens to correct all kinds of astigmatism, especially medium and high astigmatism and irregular astigmatism; It can be specially designed and processed, and has a good corrective effect on patients with congenital abnormalities, keratoconus, eye trauma, high corneal deformation after operation and so on.
corneal orthosis
this is another promising contact lens. It is a specially designed RGPCL. Through reasonable physical correction of the cornea, it can quickly reduce the degree of myopia and significantly improve the naked visual power of medium and low myopia. Most importantly, it can effectively control the growth of myopia. It has obvious effect and exact effect. It is especially suitable for adolescent myopia patients with rapid development of myopia. At present, this technology has attracted high attention from experts at home and abroad. It should be noted that corneal orthosis is a medical product, which requires high fitting technology and good supporting medical equipment. Fitting must be carried out under the strict supervision and guidance of ophthalmologists or optometrists in order to ensure its safety. Moreover, to maintain good control effect, it is necessary to wear glasses for observation for a long time.
and
should not only choose the correction methods such as frame lens or contact lens, but also pay attention to the scientific fitting technology. The optometry center of the Department of medicine of Peking University summarized and developed the [16 + 2-step] fitting method for fitting contact lenses. This medical optometry mode and scientific and standardized programmed fitting have benefited more than 2000 myopic astigmatism patients who came to the center.
and
everyone will have different degrees of ametropia at different times in their life. We suggest that everyone should establish a complete set of optometry files, check and diagnose regularly from childhood to old, and timely give appropriate correction and treatment for some eye diseases and ametropia problems found at any time, so as to ensure that they can remain clear, comfortable and transparent at any time Persistent visual state.
