Enthusiastic two-pair owner review of CHIMI sunglasses
I bought two pairs last summer and wear them daily. I LOVE them. They look expensive and the quality is there.

Explanation of AR coating issue causing reflections on CHIMI 04
Unfortunately, if the lenses don't have an AR (anti-reflective) coating on the back this can happen. I find it's only really flat lenses that give me this problem along with certain lighting conditions, ie. the sun at my back. Short of replacing the lenses I'm not sure what else can be done. Sorry, wish I had better news.
