<strong>Background and Objective:</strong> Glare can affect vision in normal and abnormal individuals. It seems that threshold and normal values of glare have been less mentioned in various sources. The aim of this study was to determine acuity preserve in glare situation in normal subjects. <br>
<strong>Methods:</strong> 48 subjects (96 eyes) aged 18 to 25 years with normal visual acuity, and without any refractive error participated in this study. The acuity preserve in glare situation was measured at different light intensity conditions with Metro vision glare test at different luminance and visual field.<br>
<strong>Results:</strong> Glare source in each luminance at the nasal side may show better acuity preserve in glare situation. The maximum score for nasal and temporal source for 1 cd/m2 condition was 57.398 and 51.282 respectively. The same situation was seen for 5 cd/m2 (<em>P</em><0.001). However, in glare for luminance background of 1 cd/m2, and 5 cd/m2 were significantly different (<em>P</em><0.001). The acuity preserve in glare situation for 5 cd/m2 background was higher than 1 cd/m2 luminance in both temporal and nasal sides.<br>
<strong>Conclusion:</strong> Acuity preserve in glare situation in luminance of 5cd/m2 in both temporal and nasal was more than1 cd/m2. Acuity preserve in nasal glare situation was more than temporal glare situation.<br>
