When emotions like attractions rises iris gets to be bigger comparatively.

Okay. And...?

[Bio freck]

This depends on the autonomic nervous system how it is able to dilate or constrict with respect to emotions.

[HGrimston]

When you undergo arousal, or any kind of stressor in general, your body is releasing glucocorticoids. One of the reactions to glucocorticoids is iris dilation, because this lets your eye receive more light, and thus you see more, and can react to the situation at hand. It doesn't matter if it's a dangerous situation or not - your body reacts to glucocorticoids by preparing for a stressful event, and glucocorticoids get released when you become emotionally aroused or stressed.
