SPHERE (SPH)

SPH, for Spherical, refers to the refractive correction in the prescription.  Minus (-) are for near sightedness, and Plus (+) values are for far sightedness.   If "PL" or "Plano" is written for the either SPH value on your prescription, you should select a value of 0.00.

OD-SPH is spherical correction for your RIGHT eye.

OS-SPH is spherical correction for your LEFT eye.

CYLINDER (CYL)

CYL, for Cylinder, refers to the strength of the correction for the astigmatism in the eye.  It can be either positive or negative.  If there is a CYL value on an eye, there must be an Axis value on that eye.

If "DS" or "SPH" or "spherical" is noted in the CYL space on your prescription, you have no astigmatism in that eye.  In that case, enter 0.00 in both the CYL and Axis.

OD-CYL is cylinder correction for your right eye.

OS-CYL is cylinder correction for your left eye.

AXS AXIS

AXS, or Axis, refers to the angle of the correction for the astigmatism in the eye (if one exists) from 1 to 180.  If there is an Axis value on an eye, there must be a CYL (Cylinder) value on that eye.  If there is no Cylinder value or if the value is zero, the OD Axis value is entered as 0.00.

The Axis value is usually written as 3 digits, which means if your Axis value is 5, it is often written as 005. This Axis value is still 5, regardless of how it is displayed.

OD Axis is Axis correction for your right eye.

OS Axis is Axis correction for your left eye.

PD Range

Pupillary Distance (PD) is the distance, in millimeters, between the center of one pupil to the center of the other. The PD is needed to manufacture your eyeglasses because it determines the exact optical center of the lens, which is the point where you look through the lens. PD is especially important for manufacturing progressive lenses.

Once you have your PD, you can upload your photo to the Frame Fit tool and begin trying on glasses. The Frame Fit tool allows you to see exactly what the glasses look like on you and how well they fit the size and shape of your face. If you don’t have your PD, you can find out how to measure it
