Know what the numbers mean.
Your prescription is a set of instructions for the lens maker. Select each term to understand its role.
Cylinder: astigmatism correction
CYL shows the additional lens power used to correct astigmatism. If your prescription has no CYL value, it may be left blank by your eye-care professional.
Axis: the direction of correction
Axis is measured from 1 to 180 degrees and works together with CYL. It describes orientation, not the strength of the prescription.
Pupillary distance: lens alignment
PD is the distance between the centres of your pupils in millimetres. Accurate PD helps place the optical centre of each lens correctly in front of your eyes.

Prescription questions
Clear answers before checkout.
Can I upload my prescription after ordering?+
Where the product offers prescription lenses, you can provide details during selection and may also send the prescription through the contact route shown after ordering. Production begins only after the required details are confirmed.
What prescription details do I need?+
Provide values for both eyes exactly as written, including SPH, CYL, Axis, PD and any ADD or prism values present. A clear image of the complete prescription helps prevent transcription errors.
What is the difference between single-vision and progressive lenses?+
Single-vision lenses use one prescription power across the lens. Progressive lenses combine multiple viewing zones without a visible segment line and require suitable prescription and fitting details.
Can every prescription fit every frame?+
No. Lens thickness, prescription strength, pupil position, frame size and curvature can affect suitability. Contact us or your eye-care professional when your prescription is strong or includes prism or other special requirements.
