Case: 12-year-old child after a month of free treatment of myopia therapy device, vision from 4.2 to 4.4, now the free use of the therapy device time expires, the sale of the therapy device business wants to pay nearly 10,000 yuan of treatment fees (a year of costs), the parents consulted the ophthalmologist: myopia therapy device can cure myopia? South China Sea People’s Hospital ophthalmology master Liao Aiping, attending physician to parents’ response: 1, the principle of the current myopia treatment instrument is modified with amblyopia treatment instrument, generally will choose the far and near back and forth movement of the visual marker, children follow the visual marker a far and near movement, eye muscles will be properly relaxed, coupled with moderate light, grating visual marker exposure, children’s visual acuity will fluctuate in the short term, such as before only 4, 2 vision, after using the treatment device has 4, 4 vision. But parents often ignore another problem, myopia refers to children have myopia, you use the treatment instrument, because the eyes get relaxed, vision has improved, but myopia is not really reduced, so generally this so-called myopia treatment heart will only judge the effectiveness of the standard of vision, will never give you the degree of test. 2, long-term gaze myopia treatment instrument, and gaze at the phone distance is similar, and the treatment instrument for strong light exposure, long-term treatment, but will accelerate the development of myopia. 3, the key to preventing myopia is actually a change in parental perception, many parents have many misconceptions about myopia and myopia prevention and control: not enough attention to myopia, blindly gullible myopia treatment equipment, especially the child’s resistance to wearing glasses, these misconceptions will directly lead to the rising number of children myopia. 4, parents are a mirror of their children’s learning, if parents can not maintain good eye habits in front of their children, it is difficult for children to rely on self-control to resist the temptation of the “poisoned apple”, myopia prevention and control will always be a paper talk.
