Study Summary
The purpose of the study is to determine if progressive addition lenses (PALs) versus single vision lenses (SVLs) slow the progression of low myopia in children with poor accommodative responses (i.e., large accommodative lags) and near esophoria.
Primary Outcome
Measured in diopters (D) using cycloplegic refraction sphere (amount of myopia) and cylinder (amount of astigmatism at an angle (axis)). Spherical equivalent (SE) is the sphere plus 1/2 the cylinder. For baseline and each time point, a SE was calculated for each eye for each of the five trials of cycloplegic autorefraction; the median for each eye was averaged to obtain the SE used for analysis. Change was calculated as SE at baseline minus SE at 3 years. A negative value indicates that the myop
