Question: Change in Axis on my glasses prescription?
I do not see really well with glasses with 105 axis.
I do not really know how big an effect the change has.

The axis is to tell them how to orient the cylinder portion of your prescription in the lens with respect to your eyes. If the cylinder part for the right eye is really weak, during the eyetest, it might be hard to perfectly tell them, when they start asking "is this better, or this" because the differences will be pretty slight. So there is possibly a little "experimental error" in the axis determination.
Take the glasses you have now, close your left eye and tip the glasses so the right lens rotates clockwise and counter clockwise a few degrees and see if you see better either direction. This would suggest the axis doesn't match your eye. It might be so slight you can't even tell.
The axis is only 1/3 of the prescription.
We really can't tell much by just knowing the change in the axis...what about the rest of it ?
