Customization Guide

1. Obtaining a Valid Prescription

  • Schedule an Eye Exam:
    Ensure you have a comprehensive eye exam from an optometrist or ophthalmologist. Your prescription should be up-to-date and clearly list all the necessary parameters.

2. Understanding Your Prescription Parameters

When reviewing your prescription, please take note of the following key parameters:

  • Sphere (SPH):
    Indicates the degree of nearsightedness or farsightedness. For example: -2.75 or +1.50.

  • Cylinder (CYL):
    Measures astigmatism. If you do not have astigmatism, this value may be listed as “0” or left blank.

  • Axis:
    Required if you have astigmatism, this value (ranging from 0° to 180°) defines the orientation of the cylinder correction.

  • Pupillary Distance (PD):
    The distance between your pupils, measured in millimeters (mm). In some cases, you may need to provide both distance PD and near PD.

  • Addition (ADD):
    This is applicable if you require multifocal or progressive lenses and is commonly used for reading or presbyopia correction.

    • Left Eye (OS):

      • Sphere (SPH): e.g., -2.50

      • Cylinder (CYL): e.g., -0.25

      • Axis: e.g., 170°

    • Pupillary Distance (PD): Provide the total PD (e.g., 62mm) or individual values for each eye if required (e.g., 31mm/31mm).

    • Addition (ADD): If you need multifocal lenses, input the additional reading prescription.

  4. Review and Submit:
    Carefully review your entries to ensure that all details match your current prescription. If you have any questions, use our FAQ or contact customer service before proceeding. Once everything is confirmed, submit your information to continue with the purchase.

4. Important Considerations

  • Accuracy of Data:
    Ensure that all prescription details are accurate and match your latest eye exam results. Incorrect information may lead to improperly crafted lenses, affecting visual clarity and comfort.

  • Units of Measurement:
    Prescriptions typically use diopters (D) for lens power and millimeters (mm) for pupillary distance. Verify that you are entering the correct units.

  • Need Assistance?
    If you have any uncertainties or need help measuring your PD, please consult your eye care professional or contact our customer support for guidance.

  • Regular Updates:
    It’s important to have your eyes examined regularly to ensure that your prescription remains up-to-date, as vision can change over time.
