Because they are clones, why is Cosima the only one with bad eyes?
shareDifferent environmental or physical factors likely contributed to the deterioration in her eyesight. She's also the only one that we know of who is gay, so clearly they are not completely identical in every way.

Allison is the only clone that struggled with alcoholism, Beth, I believe, had a pill addiction, and Sara is the only one that could get pregnant. Cosima is also the only one of the group thus far to get sick.
sharePlot hole. It's what happens when you're so concerned with your show winning awards than small details like...the plot.

This doesn't contradict anything because it is absolutely a possible thing for her to have poor eyesight when the others don't.
