We are redefining the direct-to-consumer eyewear industry with our innovative photo-based measurement system. This technology not only keeps costs low but also delivers exceptional accuracy, ensuring that every David Kind customer gets the perfect fit. Our patented system allows us to measure your prescription lenses precisely, so you can enjoy clear and comfortable vision without compromise.
Our Home Try-On experience is a favorite among our customers, as it lets them feel the frames before making a purchase. What sets David Kind apart is the final step: we ask for a photo of you in your chosen frames. This image helps us accurately determine your pupillary distance and vertical lens height—measurements that are typically taken during an in-person visit at an optometrist’s office. These details are essential for customizing your lenses correctly, and our system ensures they’re spot-on.
These precise measurements are crucial for optimal vision. They can be captured by your eye care professional or through our advanced photo technology. Thanks to our patented system, we’ve reduced the rate of eyeglass returns from the national average of 11% (including in-person purchases) down to just 3%. That’s a significant achievement we're proud of.
To learn more about how these measurements work and why they matter, check out the details below. You’ll also discover how our patent plays a key role in delivering the clearest, most comfortable vision possible. Find out more about our patent here.

**What is Pupillary Distance (PD)?**
Your PD is the distance between the centers of your pupils, measured in millimeters. It's a critical measurement that ensures you look through the best part of your lenses for sharp vision.
**What is Optical/Ocular Center Height (OC)?**
This is the vertical position of the lens center relative to the bottom of the frame. It varies depending on the frame you choose, and while many brands use a standard setting, David Kind uses our photo technology to capture the exact OC height for your unique face shape and frame choice.
**What is Segment Height (SEG)?**
This is specific to progressive or bifocal lenses. It determines where your eyes will focus within the lens for near, intermediate, and far vision. The SEG height is adjusted based on your lifestyle and daily activities, and our system ensures this is done accurately for maximum comfort.
While many online retailers offer virtual try-ons, our Home Try-On experience gives you the chance to see and feel the frames in real life. When combined with our patented photo measurement system, we capture even the smallest details that could otherwise be missed. Inaccurate measurements can lead to visual discomfort, headaches, and blurred vision. So, even if the frames look great, incorrect measurements can make the lenses uncomfortable to wear.
