Emotional resilience is the most surprising for me. I am much less likely to get upset or irritable.
A new thing that is interesting for me is an improvement in vision. Or at least a decrease in prescription for my contact (I go monovision with only one contact as my close vision is best with no alteration). The highest it has been was -1.75 and now it is down to -1.25. It has become an annoyingly flimsy piece of saran-wrap to get in the eye, lol. Fortunately for me I do the month-long extended wear so I only have to deal with it once a month.
