Introduction: This study aimed to evaluate the correlation between Quality of Life Impact of Refractive Correction 
(QIRC) score with visual disturbances and contrast sensitivity in spectacle wearers. Methods: A total of 21 spectacle-corrected moderate myopes was recruited. Subjects completed the QIRC questionnaire for quality of life assessment. The functional and emotional QIRC scores were analysed separately. Visual disturbances were evaluated using 
the Halo and Glare Simulator, and contrast sensitivity was measured by the M&S Smart System II. All measurements 
were taken binocularly in 1 lux illumination. Spearman’s test was employed to evaluate the correlations. Results: The 
most common visual disturbance was diffuse glare. The functional QIRC score was significantly correlated with glare 
intensity (r = -0.54, P = 0.01). Whereas, the emotional QIRC score was significantly correlated with contrast sensitivity (r = 0.45, P = 0.04). Conclusion: The functional QIRC score is lower when the glare intensity is greater, and the 
emotional QIRC score is higher in person with greater contrast sensitivity. Hence, glare intensity and contrast sensitivity measurements are suggested to predetermine spectacle wearers’ functional vision and well-being, respectively
