Popis:	We determined the repeatability-reproducibility of refraction values and pupil size measured using the Spot Vision Screener and compare the obtained values with those measured using the binocular open-field autorefractor Grand Seiko WAM 5500 in healthy adults. This cross-sectional study included 22 eyes of 22 healthy adults with emmetropia to myopia. For each participant, spherical equivalent value, cylindrical value, and pupil size were measured in the right eye using the Spot Vision Screener and Grand Seiko autorefractor devices by two different orthoptists under two conditions: monocular and binocular (three consecutive refraction measurements). Repeatability-reproducibility of values measured using both devices were evaluated using intra-class correlation coefficients (ICCs). The mean spherical equivalent value measured using the Spot Vision Screener was -2.79D in the monocular condition and -2.69D in binocular condition, which showed a small significant difference to those measured using the Grand Seiko autorefractor (-2.98D and -2.93D, respectively). The mean cylindrical value measured using the Spot Vision Screener was -0.59D in the monocular condition and -0.52D in the binocular condition, which showed a small significant difference compared with those measured using the Grand Seiko autorefractor in the binocular condition (-0.70D and -0.75D, respectively). Correlation coefficients of the spherical equivalent values, cylindrical values, and pupil sizes measured using both devices were R=0.959 (P
