Thankyou for really simplifying this. So this is what I understood please confirm if this is correct:

My current prescription is –
RIGHT SPH: 1.75
RIGHT CYL: 0.75, AXIS: 20
LEFT SPH: 2.25
LEFT CYL 1.50, AXIS: 140

So Differentials should be:
My current prescription is –
RIGHT SPH: 0.5 (1.75 – 1.25)
RIGHT CYL: 0.50 (0.75 – 0.25), AXIS: 20
LEFT SPH: 1.00 (2.25 – 1.25)
LEFT CYL: 1.25 (1.50 – 0.25) , AXIS: 140
