Prescriptions
1. What do I need to order prescription eyeglasses?
A current eyeglass prescription with SPH (and CYL and AXIS if you have astigmatism) for each eye, plus your PD.
2. What do OD and OS mean?
OD is your right eye; OS is your left. Some prescriptions write R and L. Full guide: how to read your prescription.
