My contact lens prescription last year was:
OD -4.75 -0.75 x010
OS -6.50 -0.75 x020
This year my prescription is:
OD: -5.25 -0.75 x010
OS: -7.00 -0.75 x120
My question is: could the axis of one eye really have changed by 100 degrees in one year, or is it more likely that one number was jotted down incorrectly?
Thank you!
