I'm farsighted and have astigmatism (eyes don't focus synchronized, so no real 3d sight, more like a tv screen)
While I still can hear high sounds (like dog whistles) very good, I have quite some problems making out human voices against background noise. Not exactly helping in social situation (party), since I find it extremely difficult to talk and understand if there is loud music.
