Why he does this
He tested the method on his own children first.
Twenty-five years ago, Linco began working in children's vision care in China — the country with the world's highest rate of childhood myopia. Day after day, he watched the same scene: a parent hearing "your child is nearsighted," then panicking, searching at midnight, and falling for expensive products that promised miracles.
Over 10,000 families later, he had distilled everything that actually worked into six defense layers — light environment, red light therapy, optical correction, near-to-far viewing, vision training, and nutrition & medical support — all organized around one number most parents had never heard of: axial length. He called it the 6S Method.
Then he did what no product can copy: he used it on his own two sons. Nine years of prevention for the elder, four and a half for the younger — neither of them is nearsighted today.
He wrote No More Myopia Panic so that no parent has to face that first diagnosis alone, and built the free axial-length tracker at 6smyopia.com so every family can watch the one number that matters. A father's mission: No more myopia for our children.
