The Measurement of Refractive Power using Manual Lensmeter and Automatic Lensmeter for Optical Lenses

To draw a conclusion of standardization for measurement of refractive power in a spectacle lens, we measured vertex diopter of the three major manufacturers spectacle lenses, which are being chiefly used in South korea, by a telescopic manual lensmeter and a digital automatic lensmeter for comparison from both. The method classifying the lens by different refractive power for each S-5.00D, S-10.00D and S-15.00D to analyze reliability of the results from the measurement, show that a manual lensmeter has more accurate than a digital lensmeter in case of measurement of the minus diopter spherical lenses.
