The Evil inclination dominates only on what the eye sees. (Sotah 8A).
The sense of seeing emerges from the ‘black’ of the eye, that is judgement and severity, therefore that is what makes a person sin.
As it says ???? ??? -and it was day, this is the Yetzer Hatov, ???? ????-and it was night this is the Yetzer Hara (Midrash).
The night is dark like the ‘black’ of the eye, that initiates the Yetzer Hara.
