How to figure out my contact prescription?

I'm trying to buy online contact called circle lenses and I need to find out my true prescription. The information give to me on the paper is
On my right eye;
B.C: 8.7
DIA: 14.2
SPH: -5.00
CYL: -1.25
AXIS: 180

On my left eye;
B.C: 8.7
DIA: 14.2
SPH:-5.50
CYL: -1.25
AXIS: 170

I learned through online searching that SPH is the power but also that CYL means I have some astigmatism and that that needs to be considered, as well as AXIS, to my prescription.Am I supposed to add them in or something?

Help please! (before my order ships out ;c )
