1. A computer-implemented method for estimating and tracking refractive error progression of an individual, comprising:

  • estimating a percentile of Spherical Equivalent Refraction (SPHEQ) as a function of the individual'"'"'s age and at least one of country, region, gender, ethnicity, or parental history by comparison to a reference population by modeling data from a selected dataset;

    estimating an expected SPHEQ trajectory of the individual over a future predetermined period of time using a predetermined set rate of change;

    determining an expected SPHEQ trajectory using an ametropia control treatment;

    displaying, on a graphic user interface, a comparison of the estimated expected SPHEQ trajectory of the individual with the expected SPHEQ trajectory using the ametropia control treatment;

    displaying, on a graphic user interface, a comparison of the estimated percentile of SPHEQ with the estimated expected SPHEQ trajectory of the individual; and

    using the comparisons to estimate and track the refractive error progression of the individual.
