What is the source for the claim that “Currently, the US has banned over-the-counter myopia glasses”? Glasses for mild myopia (up to about −4.0) are available without a prescription on Amazon (https://a.co/d/04RQUEk8 is the kind I wear when I take my contacts out), and AFAICT that is perfectly legal. AFAIK prescription lenses are only required for correcting more complex or multiple refractory problems like myopia+astigmatism, or myopia+presbyopia.
It seems like a highly neglected intervention to simply provide free myopia glasses in developing countries without expensive screening. If people put on a pair of them and it improves their vision, it shouldn’t require a professional to tell them to pick the weakest pair that seems to work and take them home to try.
