I don't know if Dhrishti Bommais would scare off the evil eye, but it would scare me off :) My mother would never say she was superstitious, but she was devoutly Catholic. Whenever there was a report of bad news, she would cross herself (make the sign of the cross). She would reject the idea completely that this was superstitious, but there was no doubt she was invoking the protection of God. Same for pictures of statues or favorite saints. These offered protection from different kinds of harm. One person's religion is another person's superstition, I guess.
