Prescription Detail

About Your Prescription Detail....

It is really important to have your prescription correctly submitted to us and therefore please do read the following instructions carefully.

Please leave the options of any part as No Prescription or None unless it appears on your prescription.

The prescription details you need to fill out:

Sphere (SPH): the amount of long (+) or short (-) sight your eye has. The farther the number away from 0.00, the stronger and thinner then prescription lens required. Thus, for SPH higher than +6.00 or lower than -6.00 please choose prescription lens 1.61 or 1.67.

Cylinder (CYL): the amount of astigmatism, or visual distortion, caused by an irregularly shaped cornea. For CYL higher than +3.00 or lower than -3.00, we will charge for extra cost as personalization are needed before making the original lenses, which may take additional 3-5 days.

AXIS: the direction of the astigmatism, measured in degrees.

Near/Add: the amount of additional correction needed to focus at close distances.

Pupillary Distance (PD): the distance between the middle of the pupil of your eyes, measured in millimeters. If this does not appear in your prescription, you can measure it by your self or ask someone to measure it for you. As a guide, an average PD can vary from 65mm to 75mm. The national average PD is 63mm. If you have difficulty measuring your PD by your self or to provide it, we can take the national average PD to make the lenses for you.

Please double check the prescription details that you given to us for confirmation.

If you have any difficulity in reading your prescription, please conatact us or scan it and email it to us.
