My old glasses prescription is:

SPH CYL AXIS
Right (OD): -1.25 -0.5 180
Left (OS): -1.25 -0.75 15

The new one my doctor made is:

SPH CYL Brand
Right (OD): -1.25 -0.5 170
Left (OS): -1 -0.75 15

Will staying with the old glasses cause me any problems. My eye doctor says to get the new ones because switching between them and my new contact prescription will cause problems.

Thanks

My current contacts prescription is:

SPH CYL AXIS
Right (OD): -1.5 - -
Left (OS): -1 -0.75 20
