Well, in my opinion, it is not right that blue eyes can see well in dark. Generally speaking, eye color has nothing to do with sight and it is just a genetic thing. And you should know that the pupil that looks like a black dot in the center of the eye controls our vision. Also, the colored part of the eye is called the Iris and it controls the light that enters the eye. In order to see at night, the pupil expands to a larger circle and to see better in a brightly lit situation the pupil constricts. So that's how we can see at night once the eyes adjust. But there is nothing to do with the color of your eyes, even your eyes is blue.
