I have a problem with the landlord now, and I bought my aunt through WeChat. The other party is also a full-time voice, and keeps sending pictures of successful cases. My son used it seriously for almost three months and went to the hospital for an eye examination. His left eye rose by 50 degrees, his right eye by 75 degrees, and his astigmatism by 25 to 50 degrees. I was so angry that I wasted my child's time to control myopia. If I had known, I would have fitted my child with orthokeratology glasses. At the very least, the degree will not rise so fast.
