The eye grows automatically in response to what is in focus. If too much is constantly in focus the eye grows longer to blur it. This is especially important in peripheral vision which is why lenses are finally coming out with blurred edges to slow myopia progression. Ophthalmologists who don’t know this and don’t tell people to use lenses as little as possible and dont think screens cause myopia are negligent (and hopefully will start getting sued until they learn) especially when prescribing lenses to children when this matters most. The eye generally stops being able to respond to the over focus stimulations in adulthood. And children with unnecessarily worsened myopia from negligent doctors are at higher risk for permanent blinding illnesses earlier in life and more frequently. If your eye doctor doesn’t know about low dose Atropine for children, then leave them (or explore legal options if your child’s myopia has gotten significantly worse). There is no known way to reverse the elongation of the eye and therefore reverse myopia, for now it’s permanent. Any claims to reverse myopia without surgery are pure quackery, like the Bates method.
