Purpose: Comparison with contrast sensitivity between binocular and monocular of 20s adult was measured by spatial frequency 3.0, 6.0, 12.0 and 18.0 cpd and compares difference between monocular and binocular and difference between male and female.
Methods: Topcon CV-3000 Phoroptor was used for full correction of 99 ophthalmic optics students and contrast sensitivity were measured by using Vector Vision CSV-1000E at 2.5 m in photopic condition (100 cd/m2).
Results: Photopic condition at 2.5 m, average contrast sensitivity of entire subject was 52.54, 80.40, 36.79 and 13.56 with right eye and 52.33, 81.29, 41.73 and 14.22 with left eye in 3, 6, 12 and 18 cpd. For both eye 65.46, 113.69, 52.04 and 19.44 were measured. The contrast sensitivity of male was 58.22, 83.52, 37.89 and 13.82 with right eye and 56.03, 46.68 and 15.67 with left eye in spatial frequency of 3, 6, 12 and 18 cpd. Both eyes were measured to 70.89, 120.96, 56.56 and 19.89. The contrast sensitivity of female was 46.50, 77.09, 35.61 and 13.28 with left eye and 48.40, 70.43, 36.47 and 12.68 with left eye in spatial frequency of 3, 6, 12, 18 cpd. Both eyes were 59.68, 105.97, 47.23 and 18.95.
Conclusions: Contrast sensitivity value of binocular shows higher than monocular to both male and female. Contrast sensitivity of difference between male and female were statistically remarkably higher to male in right eye 3 cpd, left eye 6 cpd, 12 cpd and both eye 3 cpd. In other frequency, there was no statistical significance but male shows higher.
