I've gained about 50% of my vision back. I had eyelash extensions put on, I was the guinea pig and knew it but the whole thing went south fast. Chemical burns on top of abrasions on your retina (caused by someone gluing your eyelid to your retina then ripping it off) the. Scratches on top of all of that...not fun. Both eyes got chemicals burns but only 1 got the abrasions. Unfortunately, it was the eye with good vision that took the brunt.
