| 1. Myopia is the result of overdevelopment of the eyeball, which is essentially a shortening of the eye axis. | 150 (27.17) | 402 (72.83) | ||||
| 2. The complications of high myopia are mainly fundus lesions, such as retinal detachment, retinochoroidal atrophy, macular haemorrhage, macular fissure, etc. | 380 (68.84) | 172 (31.16) | ||||
| 3. Low-concentration atropine drops are effective in slowing the development of myopia. | 267 (48.37) | 285 (51.63) | ||||
| 4. Mydriasis is a routine form of eye examination and treatment. | 369 (66.85) | 183 (33.15) | ||||
| 5. To give your eyes adequate rest, get up and move around every 20 min when working and studying, and stand in front of a window and look 20 feet (6 m) away for at least 20 s. | 507 (91.85) | 45 (8.15) | ||||
| 6. During home Internet classes, you should ensure that the room is well-lit and adjust the brightness of your child's electronic devices appropriately, not too bright or too dark. | 529 (95.83) | 23 (4.17) | ||||
| 7. Outdoor exercise is also crucial to myopia prevention and control, but it does not matter whether the child is under daylight or not; he/she should be allowed to do more outdoor activities. | 112 (20.29) | 440 (79.71) | ||||
| 8. Children should not read at home in too much or too little light. Make sure that indoor lighting and eye protection lamps are on at the same time. | 510 (92.39) | 42 (7.61) | ||||
| 9. Wearing frame glasses is one of the best ways to control myopia; moreover, there are other options, such as Keratoscope, as well as reducing close reading & learning and increasing outdoor activities. | 503 (91.12) | 49 (8.88) | ||||
| 10. If you need to do screen reading for a long time, you should wear anti-blue light glasses to block the harmful blue light to the eyes as much as possible. | 462 (83.70) | 90 (16.30) | ||||
