The online lensometer: How it works and why you need it on your site 

A digital lensometer can help you resolve one of the biggest friction points of the online eyewear shopping experience.

Over 60% of adults in the US alone wear prescription glasses. For many of them, one pair is not enough. 

Most people like to have a spare pair tucked away for emergencies, in case their glasses get lost or break. Usual wear and tear means that a substantial number of consumers are looking to upgrade their eyewear at any given time. There are also those style-conscious customers who treat glasses as a fashion accessory and buy more frequently as a result. 

For eyewear retailers, this means more potential sales, which is great news! But there’s a catch. (Isn’t there always?)  

Many customers don’t have their prescription… 

While most consumers (85%) are happy with their current prescription, only 50% actually have their prescription details when they are ready to buy new eyewear online.  

This puts retailers in a bind: If they conduct a new eye test, they typically drive their customer away from their business and into an optical shop that provides exams and glasses in one place. And that’s far from ideal.  

The best solution to this particular problem is a digital lensometer: a tool that gets the existing prescription details from an existing pair of glasses. 

Lensometers can help close the gap

The lensometer we are familiar with (also known as a lensmeter, focimeter, or vertometer) is used by optometrists to ensure the accuracy of a lens prescription, to check whether lenses are mounted correctly, or to mark and position uncut lenses properly in a frame. A lensometer can also help optometrists determine the prescription of a lens by measuring several aspects, including prism, sphere, axis, and cylinder. 

The technology behind the lensometer is not new; in fact, it dates way back to the work of Antoine Claudet, a French photographer and artist, who in 1848 developed the focimeter, which helped find the correct focus for photographic portraits. Some thirty years later, the Dutch ophthalmologist Herman Snellen, father of the Snellen eye chart, developed the phakometer, which measured the accuracy and power of glass lenses. In 1921, these inventions were developed into the lensometer as we know it today, and the patent was filed in the US by the American Optical Company. 

The lensometer in a digital world 

When it comes to buying prescription glasses online, 47% of consumers don’t carry their prescription details on them. Although they might be well in the mood to browse and buy prescription glasses, they must have their prescription to complete their orders. This is classic friction—and as you can imagine, it creates a lot of drop-off and incomplete orders. 

Today’s eyewear retailers can use a lensometer to retrieve the lens prescription from the customer’s current glasses, even when that customer doesn’t have or know their current prescription.  

Now, online retailers can access a digital lensometer—to help them close the crucial prescription gap in online eyewear shopping. 

How a digital lensometer works, in 3 simple steps 

For customers who don’t have their lens prescription handy, Luna’s digital lensometer makes shopping online for prescription glasses so easy and ensures accurate, usable results.

Step 3: Shop for prescription glasses!
