    Ok, so the sph stands for sphere so you need -0.75 correction, since you are nearsighted, cyl is for cylinder which is the astigmatism ( unequal curvature of the front surface of the eye) and the axis is the position in which the cylinder must be corrected for. Your left eye does not have astigmatism or at least enough to be corrected for.
