The role of different myopia intervention methods in slowing myopia progression in undercorrected myopic eyes, myopia progresses faster than in fully corrected eyes. Once again, it is important to mention that the prescription is based on the principles of medical optometry: ectropia is sufficiently corrected and endopia is undercorrected. Most myopes are emmetropic and should be adequately corrected. Undercorrection is the catalyst for myopia! Multifocal lenses can be an option as a correction method for children with myopia with near internal obliquity or a large amount of adjustment lag, and the way glasses are used is also important. — The fitting of children’s progressive lenses must be about indications and should not be put on casually, otherwise it will easily trigger more eye position abnormalities. Even with progressive lenses, it is important to pay attention to the guidance of children’s use. In children who are fitted with progressive lenses, the lower plus light should be selected individually according to the different amount of occlusion and different amount of adjustment lag in the pair of near vision. –The lower light should be determined based on the results of the visual function test when fitting progressive lenses. Peripheral refractive control lenses are used for myopia control in children whose parents have a history of myopia. Soft corneal contact lenses designed with peripheral refractive control technology have an advantage over frames in myopia control. RGP lenses can be one of the correction options available to children. No more “No contact lenses for children! And it’s hard contact lenses!” The positive effect of keratoplasty on myopia intervention in children and the slowing effect on the growth of the eye axis is an objective fact. Keratomileusis is now more consistently recognized as an effective tool for myopia control in children. The prevalence of myopia is lower in children who spend more time outdoors than in those who spend less time outdoors. Increasing outdoor activity is a possible way to intervene in myopia.
