    What are Prism Glasses?

    Prism glasses, also known as prism correction glasses or prism lenses, are specialized prescription eyewear designed to correct double vision. They are specifically prescribed by eye doctors for individuals with binocular vision disorders, where the eyes struggle to work together effectively. If needed, this correction is included as part of your overall glasses prescription by your eye doctor.

    How do Prism Lenses Work?

    Prism lenses work by bending light to make sure it hits your eyes the right way, fixing double vision. This happens when your eyes aren't working together, and you end up seeing two of the same thing. With prism glasses, the light is adjusted so both your eyes see things the same way, getting rid of double vision. They do this by slightly shifting the image up, down, left, or right, helping your eyes to team up and see things as one.

    Prism correction often results in added lens thickness. Choosing a thicker plastic frame can effectively mask this, ensuring a seamless and comfortable fit. This smart choice marries functionality with aesthetics, accommodating your prescription effortlessly. We offer you a wide selection of frames tailored to your vision needs.

Reading Your Prism Correction Prescription

    Reading Your Prism Correction Prescription
  • Typed Prescription
    Look for a box marked "Prism" for your correction details.
  • Hand-Written Prescription
    A small triangle indicates prism correction.
  • Understanding the Details
    Prism correction is shown as a positive number (e.g., +2.00) followed by its direction—BD (Base Down), BU (Base Up), BI (Base In), or BO (Base Out). For example, "+2.00 BD" means 2 diopters of prism, base down.
    BD (Base Down): Thicker part of the lens is at the bottom.
    BU (Base Up): Thicker part is at the top.
    BI (Base In): Thicker part is towards the nose.
    BO (Base Out): Thicker part is towards the ear.
  • You might see corrections for one or both eyes, possibly with two directions needed per eye.

Entering Your Prism Correction:

A Step-by-Step Guide

Entering Your Prism Correction
  • Find the "Need Prism Correction" Option:

    After you enter your basic prescription information, look for an option labeled "need prism correction" just below the prescription entry area. Click or select this to open up additional fields for prism details.

  • Entering Prism Values:

    Once the prism correction fields are visible, you can input the specific prism values for each eye.

  • For Two Corrections in One Eye:

    If your prescription includes two separate prism corrections for one eye, don't worry. You should see a checkbox labeled "has more values." Tick this box to reveal more input fields where you can add the second prism correction for either eye.

  • Pay Attention to Details:

    The most important part of this process is accuracy. Each prism correction has a number value and a direction (like "up," "down," "left," or "right"). Make sure you carefully enter these exactly as they appear on your prescription.
