Sometimes my depth perception goes off after getting a new pair of glasses with no prescription change, I always figured I had ended up with a different IOR poly-carbonate formulation in the lenses. But I have no idea if that can actually cause the effect.

I experience this too, and always thought it might be caused by a change in alignment of my eye and the “center” of the lens with new frames and lens shape.
