Why won't my eye texture mirror? I am having this problem with the mirror modifier with the eyes. Blend will copy the shape, size, location, and rotation, but if I add transparency and create a texture, only the original half renders out texture, while the mirrored one doesn't register the changes.

I've tried deleting the modifier and adding another mirror modifier to no avail.

Is there a fix for this or will I have to keep duplicating the original eye and mirror it manually?
You're using a procedural texture with generated coordinates. It's normal if it doesn't mirror.
If you want this blend texture to mirror while keeping the mirror modifier you'd have to use UV coordinates with an equirectangular projection and using a linear blend texture.
Or you can simply apply the mirror modifier, separate the eyes and put the origin of each one at its center.
