The back story (originally posted here):

I am the mother of a 13-year old (named Michael), and he has been nearsighted ever since he was about 5 years old. His prescriptions started with a -1.00 in both eyes, and since then had managed to increase steadily until his most recent prescription got to -4.75 (with no astigmatism) at his most recent eye exam in July, with a new eye doctor.

If you just recently came across this site, the centimeter numbers refer to this myopia calculator.

And while at 13 years old the adult program is well suited in the majority of cases, there are a number of child related vision improvement posts here, in the child myopia section of the blog.

Hopefully we will continue to grow awareness among parents, to put them in a position to effectively help their children maintain normal, healthy eyesight.  Well done, Zaifang, thank you for posting initial results.  This is the most straightforward way to correct child myopia that I know of, and every successful report helps build confidence for new visiting parents, looking for a solution for their child’s myopia.
