Question for an Optical Expert - Important (To me!)

I noticed this last hunting season and noticed it again this evening as I was doing so field spotting. The time was before and after sun set.

As I increase power from 16X, at about 22 a fuzzy/blurry ring (solid not a ring as such) began to appear. A power increased to 48X this blur got more pronounced and shrunk.

To do any good spotting I had to have the elk between the outer edge of the field af view and the outside of the blur.

My eyes are all screwed up I but don't have this problem with a 42X night force?

I have no one else to use the scope to see if they experience this.

I recall during last season using the Zeiss lens wipes and attempting to remove the "dirt" but was never successful. Figured it was the small cataract in that eye.

The cat in the left eye is so bad that using that eye for anything is about useless.

Any input would be appreciated.

I think I'm learning something.

Went to a local out let and looked through several different scopes.

All variable scopes exhibited the phenomena I mentioned in the first post.

None of the fixed power scopes, at any power, exhibited the phenomena.

That must mean somethin'?
