I want to convert the following from spectacles RX to contact RX.
OD:- Sphere -2.75 Cylinder -3.00 Axis 7
OS:- Sphere -5.00 Cylinder -1.00 Axis 172
Is it ok to assume 172 as 170 and 7 as 10? Also I am confused if I should deduct 0.5 or 0.25 from -5. What would be the lens prescription? Thanks in advance
