I recently started HRT and noticed just yesterday that I have a very pronounced grey-ish ring around my Iris. I know this is normal, but I've never noticed it before. I was looking in the mirror and saw it. I could swear it wasn't there a few months ago. Have any of you girls noticed your limbal ring getting darker on HRT. It looks beautiful but at first I was worried that it was a health problem, ie. juvinile arcus senilus. Thanks!
