Let’s practice our eyes to identify irregular “myopia prevention and control institutions”. 1, children without dilated pupils on the optometry; without checking eye position or adjustment, on the optometry prescription. 2, some so-called myopia prevention and control institutions on the promotional materials, printed “wear” glasses without “wearing” glasses. “Wearing” is to wear glasses or contact lenses as an accessory, while “wearing” is a technical requirement that must be individualized after the optometry program to wear glasses. 3, do not be confused by some myopia prevention and control institutions of myopia prevention and control experts “ancestral or imperial medicine”. 4. When looking at myopia prevention and control products and institutional information, note that it is pseudoscience to find that the main measure is to relax children’s near-adjustment. It should be remembered that the two main focus of children’s myopia prevention and control is to increase the adjustment sensitivity and reduce the paracentral hyperopia out of focus. 5, do not just pursue high or low priced myopia prevention and control products or measures. 6. Make full use of the Internet to check the authenticity of prevention and control units and experts, and recharge myopia prevention and control knowledge in a timely manner.
