Is my new prescription wrong?

I got new glasses recently, and I've compared them to my old glasses by looking at my own custom eye exam I put up on a wall, and then covering up one eye at a time.  The new left lens seems a bit sharper than the old left lens (that's a good thing), but the new right lens seems a bit blurrier than the old right lens (not a good thing).

My old prescription (from last year) was:
L: sphere: -4.75; cylinder: -0.25; axis: 4
R: sphere: -4.25; cylinder: -0.50; axis: 176

My new prescription (with a different doctor) is:
L: sphere: -5.00; cylinder: -0.50; axis: 6
R: sphere: -4.25; cylinder: -0.25; axis: 4

The cylinder and axis for both the L and R lenses are different after only one year, but I don't know if it's significant.  Could that explain why the right lens is blurrier?  I wonder if the prescription from my new doctor is incorrect.

I got new glasses because my old ones were 10 years old and had a big scratch.

I went back, and they measured my old right lens, and it turns out my old right lens is actually -4.375 instead of -4.25.  They said if the lens is within 1/8 of the prescription, then they consider it acceptable.  But they were willing to have my new right lens redone at -4.375.

The difference in the right lens is very mild/small and insignificant.  It should not make too big of a difference.  I wonder why you even got a new pair of glasses as you likely could have gotten away with last year's pair for at least another year.  You should go back and let them know your vision is not as sharp in the right eye and they could check to make sure the lens was made correctly.
