Children are lively and active by nature, and they like all kinds of sports. The high speed and high energy impact of sports can easily lead to broken eyeglass lenses, frame deformation and eye injuries, such as eyelid abrasions, corneal damage, eye rupture, intraocular hemorrhage, and even retinal detachment, which can increase the chance of trauma for children who wear frame glasses for sports. Wearing keratomileusis at night makes it easy to play sports during the day with clear, naked vision and without any glasses. Corneal shaping lenses make sports easy and comfortable Teens under the age of 18 cannot get clear vision through laser myopia surgery, and it is very inconvenient to wear glasses for special sports such as swimming and basketball. Wearing frame glasses for sports, the lenses are easily broken by impact during sports, and the fragments splash into the human eyes or injure the facial tissues, which is difficult to find and remove. Wearing contact lenses for sports, from time to time, you will encounter dust or small particles into the eyes, easily causing eye discomfort, and a large number of bacteria will flow into the eyes with sweat, which may cause eye inflammation. In this case, for myopic children to be comfortable in sports, corneal shaping lenses are the ideal choice. After wearing keratoplasty lenses for 8-10 hours at night, the lenses will slightly compress the cornea, slowly changing the shape of the cornea and flattening the central optical zone, thus reducing myopia and astigmatism and improving naked eye vision. Keratoplasty lenses, also known as “ok” lenses, are a non-surgical procedure that reduces refractive error and improves naked eye vision by changing the shape of the cornea. It is a non-surgical method to reduce refraction and improve naked eye vision by changing the shape of the cornea. The principle of “ok” lenses is to use rigid, highly permeable contact lenses to gently shape the cornea, flattening the center of the cornea to reduce myopia and astigmatism and improve naked-eye vision, and is known as “the technology that controls and corrects myopia while sleeping. It is known as “the technology that can control and correct myopia while sleeping”. Before wearing keratoplasty lenses, you should have an eye examination. “OK” lenses are suitable for adolescents with myopia below 600 degrees, with no age limit, but are ideal for students aged 8-18. Although there is no specific age limit for the fitting of keratoplasty lenses, “ok” lens fitting is a medical practice, which has very specific requirements for the patient’s eye health, refractive status, corneal curvature, and the wearer’s compliance, immunity, and hygiene habits. Before fitting, eye examinations should be conducted with ophthalmic equipment and a comprehensive assessment should be made before deciding whether the lenses are suitable for fitting. The lenses should be reviewed regularly after fitting, and if eye discomfort occurs during the fitting period, the lenses should be removed immediately and medical attention should be sought.
