Aye, if the matter is distributed evenly as the theory states it would not be able to cause lensing, good point i hadn't thought of it. If it would cause lensing while distributed evenly then the entire universe would appear lensed, and the effect would be worse the farther away the object would be.

theoretically one might actually be able to see their own galaxy as if viewing form a distant point of view due to the amount of bending the light would be subjected to.
