The first type of contact lens that can delay children's myopia has been approved by FDA

Recently, the U.S FDA approved the world's first contact lens that can slow down the development of myopia in children It can slow down the further deepening of myopia (myopia) in children between 8 and 12 years old Myopia is the most common cause of vision impairment in the world, which is mainly caused by the change of refractive state of the eyeball The eye axis is the main factor determining the refractive state When the eye axis becomes longer, the external light cannot be focused on the retina at the fundus, and the objects at the far place will not be seen clearly If myopia, especially axial myopia, occurs, there is no way to recover the elongated eye axis Therefore, the prevention and delay of myopia is particularly important Myopia is very common in children If children have severe myopia, they are more likely to suffer from other eye diseases, such as cataract and retinal detachment earlier in adulthood Recently, the World Health Organization released the first world vision report, which shows that there are 2.6 billion people with myopia in the world, including 312 million children under the age of 19 Nowadays, there are many interventions for myopia, which have different effects and advantages and disadvantages Wearing glasses is usually suitable for the initial treatment of children's myopia, because it can make the field of vision clear and has less potential side effects; wearing contact lenses is also a treatment method for children's myopia, which requires higher sensitivity, better protection of myopia than ordinary glasses, but its risk is also higher than ordinary glasses It is understood that this contact lens, called misight, is a disposable soft contact lens developed by Cooper vision company The so-called disposable contact lens refers to that patients should discard it every day after wearing it, and should not wear it overnight It is specially designed for correcting myopia and delaying the development of myopia in children When it is placed on the eyes, misight contact lenses can correct ametropia, so as to improve the long-distance vision of myopia, similar to standard corrective lenses In addition, concentric rings around the lens focus part of the light in front of the retina (the back of the eye), which is thought to reduce the stimulation that causes myopia to progress.
