Why Eyewear Lens Measurements Matter

We are revolutionizing the direct-to-consumer eyewear industry with our patented photo measurement system. This system allows us to keep our costs low, it is elegant in its simplicity, but we mainly love the precision of our results. Our patented photo measurement system ensures that each David Kind customer receives the perfect pair of frames with accurate prescription lenses. 

 

 

Our Home Try-On experience is how most of our customers prefer to discover their frames. What truly makes David Kind’s Home Try-On and purchase process unique is the final measurement photo requested at purchase. We use this photo to dot your pupils to determine your pupillary distance and vertical height measurements.  These are the same measurements your Optometrist’s office or in-person optical shop will collect. That being said, every pair of frames will fit each person in a different way.  Our patented technology is essential to calculate pupillary distance, ocular center and segment height to ensure lens accuracy for your prescription. 

 

 

These measurements are extremely important to us and to our team.  They can accurately captured by your doctor, optician or through our photo technology. Our patented system allows David Kind to decrease the eyeglass remake rate from a national average of 11% (this includes in-person) to an incredible 3%, something our team is very proud of.  Interested in learning more? We’ve outlined a few key details about these measurements below. Plus, learn how our patent plays a crucial role to ensure the clearest and most comfortable vision.

What is your Pupillary Distance (PD)?

Your Pupillary Distance is the horizontal distance between your eyes.  This is measured in millimeters and typically does not change after adulthood.  It will ensure you look through the crispest part of the lens. 

What is your Optical/Ocular Center Height (OC)?

Your OC height is the vertical center of the lens measured from the bottom of the lens to the center of the pupil. This measurement changes dramatically depending on the frame you choose. While most online eyewear brands will center this measurement, David Kind is the only company that integrates accurate vertical height measurements. This aspect is a great example of why we need a photo of each customer taken in his or her selected David Kind frames.

What is your Segment Height (SEG)?

This measurement is specific to a progressive or bifocal lens and enables you to achieve near, intermediate and far corrections. The SEG Height is the vertical position where the eye sits within a lens and is measured from the bottom of a frame. It can be modified by your optician based on your lifestyle and your intended use (driving, computer, etc).

 

 

While many direct-to-consumer brands offer “virtual” try-ons, our Home Try-On experience allows each customer to physically experience our frames. Coupled with our patented photo technology, we are able to capture the tiny measurements that can be missed or ignored. Inaccurate measurements can cause visual distortions, headaches, dizziness and blurred vision. Ultimately, if these measurements are incorrect, the final frames might look great but the wearer could never feel fully comfortable with their lenses.
