I've used a mask here to block out the glass on the magnifying glass layer.
In actual fact, the magnifying glass source I used had some light reflections and frame shadows on the glass, so if instead of using a black mask you use a grey one, it leaves some of the glass features intact as an overlay.
Here's the magnifying glass I used so you can see what I mean about the glass

I'll have a play with this method later.
going back to mine, you can create a copy of the mirror, change the transparency and place it over the top, if you want to retain reflections, or distortions that the glass may create
