Blended texture axis' messed up when mirrored.

I made a nice eyeball today but when I went to put it in my model a problem came up. The transparency of the cornea comes from a spherical blended texture per this excellent tutorial. I didn’t exactly understand what I was doing when I set the X,Y,Z, x3 setting in the map input panel (I’m a noob), but it worked, so I didn’t worry about it. But. when I try to mirror my eye. the front of the cornea (the sphere of my blended texture) is no longer transparent (see image here). My best guess is that this is because the axis’ are getting mixed up in the mirroring. I haven’t been able to find an answer.

I can fix the problem down the road after I apply the mirror, but I’d really like to understand what’s going on here.

Hope someone can help. Thanks in advance.

P.S. I couldn’t seem to get my image to work here. Any tips on that?
