It's kind of funny, but I noticed something similar with my glasses. Turns out almost all prescription eyeglasses are made with polycarbonate lense, which tend to have a high chromatic aberration value.
My solution; I ordered a set of actual glass lenses, which I had to custom order online. It took longer, and cost a bit more.. plus I can't really use them in any sort of active environment, as if they break it could send blinding shards of glass into my eyes. But they're noticbly clearer and much more scratch resistant. I'm quite happy with them. Don't know if that accounts for your difference, but it's been helpful to me.
