Popis:	Objective: To study the correlations and differences between best corrected visual acuity in the better eye (hereinafter referred to as monocular acuity in the better eye) and binocular acuity after both eyes were best corrected separately (hereinafter referred to as binocular acuity), the relationship between both monocular acuity in the better eye and binocular acuity and reading acuity as well as reading speed were discussed in order to investigate the effect of binocular acuity in visual impairment and visual disability assessment. Methods: Two thousand a hundred and fifteen subjects ranging in age from 18 to 40 years old were recruited for the study, whose best corrected monocular acuity were less than or equal to 0.8, and other visual functions examined were normal. Best corrected visual acuity was measured monocularly and binocularly using Standard Logarithm Distance Charts. Reading visual acuity and reading speed were also determined. Experimental data were statistically analyzed using SPSS19.0 statistical software. Results: Monocular acuity in the better eye and binocular acuity was linear correlation (r=0.920, PRead Complete Article at ijSciences: V4201510853 AND DOI: http://dx.doi.org/10.18483/ijSci.853
