Inclusion criteria

✓. be within the age range of 8 to 12 years old inclusive;
✓. -0.75d to -4.50dspherical equivalent by cycloplegic autorefraction in both eyes
✓. astigmatism≤1.5d in both eyes；
✓. anisometropia≤1.0d；
✓. accommodation lag at near(33cm）in right eye by non-cycloplegic auto- refraction ≧1d;
✓. have vision correctable to at least 0.8 or better in each eye.

Exclusion criteria

✕. current or prior use of progressive addition lens, bifocals, or contact lenses in either eye( prior or current use of single vision lens allowed)；
✕. history of any of the following functional defects: strabismus, amblyopia, nystagmus；
✕. history of diabetes or seizures；
✕. history of any ocular systemic, or neuro-developmental condition that might influence refractive development；
✕. use of ocular or systemic medications known to affect accommodation, such as atropine, pirenzepine, and anti-epileptic medications in recent 3 months；
✕. history of any ocular surgery that might influence refractive development；
✕. developmental disability, attention deficit hyperactivity disorder(ADHD), or learning disability diagnosis in children that in the investigator's discretion would interfere with office-based treatment；
✕. relocation anticipated for 3 years；

What they're measuring

Change in lag of accommodation assessed by open-field autorefractor from baseline visit at 6 months after 12 weekly vision therapies

Timeframe: Baseline visit, 7th visit(7 weeks after BL), 13th visit (13 weeks after BL), 14th visit(9months after BL, which is also 6months after vision therapies )
