It took me two weeks to get used to mine. The difference to not being used to them, and being used to them was almost magical. However, I switched back to single vision because I found I was still taking them off too much to see things close up - I do a lot of sewing and crafting. I needed the larger field of vision.
Give them another week - it was like a switch going off for me when I was finally used to them. It just "clicked." Maybe that will happen for you as well.
