Background: Refractive errors are also the most common cause of vision impairments. Aim: To assess the comparison of the results of the corrective examination in a subjective way using Trial and Error in an objective way with streak retinoscope examination in students at the Ar-Raudhatul Hasanah Islamic Boarding School. Method: This study is an analytic observational with a cross-sectional data collection method, the sample of this study is students at the Ar-Raudhatul Hasanah Islamic boarding school who diagnosed myopia at age 11- ? 18 years old. In 57 subjects study, age data were obtained between 11-?18 years, with average 14.1 years, with 42 male subjects (73.7%) and 15 women (26.3%). From this study, it can be seen that the data on the way of examination subjectively and objectively to the right eye can be done by means of a diagnostic test, where the sensitivity value of the subjective and objective examination correction results in the right eye is 82.7%. The specificity of the results of subjective and objective examination correction in the right eye was 20.0%. The positive predictive value of subjective and objective examination correction results in the right eye is 91.5%. The negative predictive value of the subjective examination correction results is not accurate and the objective correction results in the right eye is exactly 20.0% and the accuracy in the subjective and objective examination in the right eye is 77.0% where the sensitivity value of the correction results between subjective and objective examination of the left eye with a value of 98.0%. The specificity of the correction results is 25.0%. Positive predictive value 88.9%. The negative predictive value is 66.4% and the value level is 87.7%. Conclusion: In this study, data was obtained that the level of sensitivity, specificity, positive predictive value, negative predictive value, and examination accuracy in each examination method had different values.
