Abstract: at present, the correction methods for myopia mainly include frame glasses, corneal shaping glasses and corneal refractive surgery. Frame glasses is a classic and effective method to correct myopia. It is simple to fit and easy to wear. However, for adolescents with high astigmatism or great difference in the degree of binocular myopia, the effect is not good. Corneal plastic lens and corneal refractive surgery should be used to correct myopia. According to the survey,
incidence rate of myopia in primary school students in China is 22.78%, 55.22% in secondary school students and 70.34% in senior high school students. Myopia has seriously affected their study and life. Therefore, the prevention and treatment of juvenile myopia is paid more and more attention by students, parents and society.
how to prevent juvenile myopia
to prevent juvenile myopia, we should do the following:
1 Control the time of reading and electronic equipment. Every time you read for about 40 minutes, you should rest for 10-15 minutes;
2. Keep correct reading and writing posture, keep the distance between eyes and books about one foot, and keep a fist distance between front chest and table edge;
3. Adjust the light of reading and avoid reading in strong light;
4. Strengthen nutrition and exercise, enhance physique, and see more green objects, which are beneficial to the eyes;
5. Take part in more outdoor activities, which is conducive to relaxing eye fatigue. What are the correction methods of
at present, the correction methods for myopia mainly include: frame glasses, corneal shaping glasses and corneal refractive surgery. Frame glasses is a classic and effective method to correct myopia. It is simple to fit and easy to wear. However, for adolescents with high astigmatism or great difference in the degree of binocular myopia, the effect is not good. Corneal plastic lens and corneal refractive surgery should be used to correct myopia. Corneal refractive surgery is mainly suitable for people over 18 years old with stable myopia. Therefore, corneal plastic lens is recognized as the most healthy visual correction option in Ophthalmology, and it is also the only effective non-surgical myopia correction method for adolescents under the age of 18. How to treat
corneal plastic lens? Because the cornea is aspheric, the vision is corrected by conventional methods such as frame lens. The incident light is refocused on the retina at the center of the cornea, but behind the central retina, resulting in further growth of the ocular axis. After wearing the corneal shaping lens, the cornea tends to be spherical, and the incident light is refocused or nearly focused on the retina in the center and central part of the cornea, which prevents the further lengthening of the ocular axis and the deepening of myopia. Two years after wearing corneal shaping, the growth of ocular axis was only half that of wearing frame glasses and soft contact lenses. The average annual myopia of wearing corneal shaping increased by 8 degrees and 67 degrees. Advantages of
corneal shaping lens
fitting method can improve the fitness and ensure that it does not affect the normal physiological metabolism of cornea. Professional doctors provide one-to-one follow-up service to ensure the safety and reliability of the treatment process.
users only need to sleep at night for 8 hours, and can restore naked eye vision during the day. Without wearing glasses, it can meet the needs of study, work and sports.
collect several corneal parameters of each user by using advanced optometry detector according to the principle of corneal refraction. Personalized design and customization for users.
4. The advanced
uses high oxygen permeable materials, full alignment, multi radian design, flat middle and steep peripheral lenses to wear on the cornea. Through the action of lenses, eyelids and tears on the cornea, the cornea shape is changed, the cornea is remodeled, the cornea is restored to the original physiological state, thereby reducing the degree of myopia or astigmatism.
