Revolutionizing the Direct-to-Consumer Eyewear Industry with Our Patented Photo Measurement System
At David Kind, we’re shaking up the eyewear game with our cutting-edge patented photo measurement system. Unlike traditional methods, this system uses advanced technology to gather precise data, keeping our costs low while ensuring exceptional accuracy. What really sets us apart is the elegance of this approach—simple yet highly effective. When it comes to providing customers with perfectly fitted glasses, precision is everything. Our photo measurement system guarantees that every customer gets a flawless pair of frames with prescription lenses tailored just for them.
Take a look at this image to see what makes our technology so special:

The heart of our service lies in our Home Try-On experience, which has become a favorite among our customers. Most people find their ideal frames through this convenient and personal process. But what truly distinguishes David Kind is the final step—a measurement photo taken during purchase. This photo helps us pinpoint your exact pupillary distance and vertical height measurements. These are the same critical metrics that would be collected at an optometrist's office or in-person optical shop. However, no two faces are alike, so every pair of frames fits differently on everyone. That’s why our patented technology is vital—it calculates pupillary distance, ocular center, and segment height to make sure your prescription lenses are as accurate as possible.

These measurements are incredibly significant—not just for us but for our entire team. They can be captured accurately by your doctor, optician, or through our photo technology. Our patented system has made a huge difference, reducing the national average eyeglass remake rate from 11% (including in-person services) to an impressive 3%. We’re incredibly proud of this achievement.

**Understanding Your Measurements**
Let’s break down some of the key measurements that matter most.
- **Pupillary Distance (PD):** This is the horizontal distance between your eyes, measured in millimeters. It remains relatively constant after adulthood and ensures you look through the sharpest part of the lens.
- **Optical/Ocular Center Height (OC):** The OC height refers to the vertical center of the lens, measured from the bottom of the lens to the center of your pupil. This varies significantly depending on the frame you choose. Most online brands center this measurement, but David Kind is the only one that integrates precise vertical height measurements. This is why we require a photo of each customer wearing their chosen David Kind frames.
- **Segment Height (SEG):** Specific to progressive or bifocal lenses, this measurement helps you achieve near, intermediate, and far corrections. The SEG height is the vertical position where your eye sits within the lens, measured from the bottom of the frame. Your optician can adjust this based on your lifestyle and intended use (like driving or working on a computer).

Unlike other direct-to-consumer brands offering virtual try-ons, our Home Try-On experience lets customers physically interact with our frames. Combined with our patented photo technology, we can capture those tiny details that might otherwise go unnoticed. Inaccurate measurements can lead to visual distortions, headaches, dizziness, and blurry vision. If these measurements are off, even the best-looking frames won’t provide the comfort or clarity you need.
