A study from the Charles University of Prague suggests that men with brown eyes are perceived to be more trustworthy than men with blue eyes.

Two separate focus groups were observed in the study by the university. However, it is not just the color of the eyes. It is the look associated with the eye color, as distinct facial features were sited in each group. Men with brown eyes tend to have rounder faces and broader chins.  

An analysis of the ratings revealed that irrespective of their own eye color, all raters perceived the brown-eyed faces as more trustworthy than the blue-eyed ones, and the results were statistically significant only for male faces.
