How do I blend a cornea and a sclera material?

So that definitely got me somewhere! Here are my results. It doesn’t look as good as it does in blender. Notice the refraction, you can see through the cornea in unreal. I have a most very basic glass shader. could this look more like in blender with a better shader setup? I have tweaked all the refraction values and this is the best i can get with this setup.
