Comparison of visibility threshold on different chromatic contrast objects / Saiful Azlan Rosli … [et al.]

The aim of this study was to compare the visibility threshold of eight plates with different chromatic contrast. The staircasepsychophysics method based on the resolution of gaps in Landolt C was used to determine the average visibility threshold. Thirty young adults with best-corrected visual acuit...
