When we see things we don't like,our pupils actually contract a little- which suggests we are trying to see less of it! Women used to put Belladonna drops in their eyes to mimic the friendly look 'o love-big pupils. Those of us who are myopic have naturally bigger pupils. This actualy helps us magnify small print.Myopic folks who are young can read fine print on jewelry. Myopia magnifies details-i think the dilation effect is an attempt to focus on details of the interesting object. There's also a theory that myopia is NOT a defect but an adaptation to low light conditions found in the colder climates,where distance vision in snowy environments might not have been as important as having an ability to discern details close up. 🌨❄👀
