UCDVA = uncorrected distance visual acuity; UCIVA = uncorrected intermediate visual acuity; UCNVA = uncorrected near visual acuity; CDVA = corrected distance visual acuity; CIVA = corrected intermediate visual acuity; CNVA = corrected near visual acuity; DCIVA = distance-corrected intermediate visual acuity; DCNVA = distance-corrected near visual acuity; SE = spherical equivalent; int SE add = addition of diopters to spectacle from the best corrected distance vision to achieve the best corrected intermediate vision; near SE add = addition of diopters to spectacle from the best corrected distance vision to achieve the best corrected near vision; D = diopter; SD = standard deviation.
