Why Eyewear Lens Measurements Matter
We're transforming the direct-to-consumer eyewear market with our groundbreaking photo measurement system. This innovative technology keeps costs low while delivering exceptional precision. At David Kind, we’re proud of the accuracy it brings to every pair of glasses we make. Our patented system ensures that each customer gets the perfect fit and the most accurate prescription lenses tailored to their unique measurements.
Our Home Try-On experience is a favorite among our customers, allowing them to find the perfect frames from the comfort of their home. What sets David Kind apart is the final step in the process: a simple photo taken while wearing the chosen frames. This image allows us to precisely map your pupils, calculating your pupillary distance and vertical height—measurements that are just as important as those taken by an optometrist or optical shop.
Every frame fits differently, which is why our technology plays such a crucial role in ensuring lens accuracy for your prescription. These key measurements are essential for clear vision and long-term comfort. Whether you get them from a professional or through our system, they make all the difference.
Thanks to our patented system, we’ve reduced the eyeglass remake rate from the national average of 11% (including in-person purchases) to an impressive 3%. That’s something we’re truly proud of. Want to learn more about how our technology works and why it matters? We’ve broken down the key measurements below, along with how they impact your vision and comfort.

**What is Pupillary Distance (PD)?**
Pupillary Distance, or PD, is the distance between the centers of your pupils, measured in millimeters. It's a critical measurement that helps ensure you look through the clearest part of your lenses. Your PD typically remains stable after adulthood.
**What is Optical/Ocular Center Height (OC)?**
OC height refers to the vertical position of the center of your pupil relative to the bottom of the lens. This measurement varies depending on the frame you choose. While many brands use a standard setting, David Kind uses our patented technology to capture the exact vertical alignment, ensuring a more natural and comfortable fit.
**What is Segment Height (SEG)?**
Segment Height is specific to progressive or bifocal lenses. It determines where your eyes will focus when looking at different distances—near, intermediate, and far. The SEG height is measured from the bottom of the frame and can be adjusted based on your lifestyle and visual needs.
While many online retailers offer virtual try-ons, our Home Try-On experience gives you the real feel of our frames. Combined with our advanced photo measurement system, we capture the small but vital details that can make a big difference in your vision and comfort.
Inaccurate measurements can lead to blurry vision, headaches, dizziness, and discomfort. Even if your glasses look great, incorrect measurements can prevent you from fully enjoying your new lenses.
