TITLE: Me [27 M] have vision issues in left eye and blind in my right eye. Not sure how to bring this up to new girls I meet/date?
POST: So I'm 27 and have health problems with my vision. I'm pretty much blind in my right eye (central vision gone due to a blood leak that led to scar tissue) and my left eye is missing about 20% of the vision. It will continue to get worse until (hopefully) stem cells are perfected to fix eye issues.

I would consider myself a decent looking guy, so I'll get Tinder matches and OKCupid matches. However, I have yet to tell any girl about my vision issues. I guess I'm scared it'll turn them off. I also don't want to tell them too soon. I've only been in one relationship since my vision issues started. It didn't work out because I pushed her away as I was unable to cope with the disability at the time. But I've been on many first dates and even 2-5 dates that just didn't work out in the end. I almost told the girl I went on five dates with but decided not to.

I'm at a better place now than I was in my last relatiosnhip. I just don't know when I should bring this up to a girl? Obviously not the first date, but I want to let her know before we would make it official and I'd like to tell her before I start to like her a lot, only to have her reject me for it. 

Can I get your guys/girls opinion? Thanks!
TL;DR: 
Vision issues which will continue to get worse, not sure how (if I even should), or when, I should bring it up to new girls I meet
