Have astigmatism. Can you tell me if I need new lens after reading this report?

my right eye SPH has increased from +4.5 to +5.0, and the CYL has increased from 0 to -0.75. Does this justify new lenses? For the past few years, the SPH has been increasing by about 0.25 diopters per year - the astigmatism has only shown itself over the last 15 months. The price for my lenses (Zeiss) is very expensive so changing every year becomes a burden. Thank you.
