Case File 01
From −1.50D to 0.00D in five months. Xiang's story.
A real follow-up record from the 6S 3.0 era, shared with the family's permission. "Xiang" is a pseudonym. This is one child's record, not a promise — individual results vary.
The curve
Every point below is a real clinic visit. The right eye (the myopic one) is the story; the left eye — which started with healthy reserve — stayed stable and even gained reserve.
| Visit date | Right axial (mm) | Right refraction (D) | Left axial (mm) | Left refraction (D) |
|---|---|---|---|---|
| 2025-04-13 | 23.48 | −1.50 | 22.46 | +0.75/−0.75 |
| 2025-05-17 | 23.31 | −0.75 | 22.41 | +0.75/−0.75 |
| 2025-06-02 | 23.20 | −0.50 | 22.36 | +1.25/−0.75 |
| 2025-07-29 | 23.18 | −0.50 | 22.36 | +1.25/−0.75 |
| 2025-09-07 | 23.08 | 0.00 | 22.36 | +1.25/−0.75 |

The protocol — combination from day one
Xiang's pre-start testing showed accommodative facility of 10 cycles/minute, meeting the standard to begin optical control directly. What made the difference was not any single tool but the 2+N synergy: two core measures plus the supporting layers, all starting together.
*Low-level red-light therapy was used under professional guidance and monitoring, as described in the book. Red-light devices for myopia are not FDA-cleared in the United States — always discuss any intervention with your child's eye care professional.
What this case teaches
Low myopia is the window
The earlier a child starts — ideally at the first sign of reserve running low — the better the odds. Xiang started at −1.50D; starting at −0.50D or at "pre-myopia" is easier still. Waiting until −4.00D is a different, harder conversation.
Combination beats any single tool
Glasses alone correct vision but do not slow the eye's growth. The 6S approach layers optical control, environment, and daily habits so each one multiplies the others.
Be honest about what "success" means
Not every child reaches 0.00D — Xiang's starting point and age were favorable. For most children, success is bending the growth curve: keeping annual axial growth well under 0.2mm. Judge your child's plan by the trend, not by someone else's finish line.
Your child's curve starts with the first measurement.
