Does the cylinder and axis change over time for eyeglasses prescriptions?

I have a prescription for glasses from a year ago indicating my sphere to be -2.75, cylinder to be -0.75, and axis to be 90 for one eye. Recently i had an eye examination for contact lens, suggesting i need -3.50 sphere for this eye, but does not indicate the cylinder and axis. This cost about $200, so i dont plan on getting another prescription for eye glasses. However i am wondering if my cylinder and axis would also change because of the change in sphere
