Normal Map bake, eyes split at verts?

Hi, thanks for reading this, your help is greatly appreciated.

I baked a normal map from hipoly to low poly mesh. The mesh is a character. The eyes are split by the vert of the low poly and looks very bad. (See attached image). Also, the normal map shows UV edges for some reason, as if it were textured with a UV snapshot.

Here is UV snapshot, it is not proportioned/optimized in space yet, but for testing. Do I simply not have enough geometry going on for my low poly? I was hoping to get away with under 3000 tris.

In the advanced options of transfer maps, I tried "match using:" -"geometry normals" instead and it worked a little better, the eyes are not broken up. However they are pulled apart making the character look bad. And I can still see the edges of the mesh, as if UV snapshot was textured on.

Tried it, didnt make a difference. I think I just need more geometry around the eyes, but still doesnt explain the edges showing like that. Also, are you supposed to diffuse texture the hipoly before you bake? or diffuse texture the low poly after bake?

The edges appearing was due to having hard edges on the normals, once i softened the edges they went away. I believe the rest of the problem was just trying to normal map too much with too little.
