GlassesOn App has changed the way people check their eyewear measurements by bringing vision technology to their smartphones. In this review, we explore its features, accuracy, benefits, and limitations to help you understand if it is the right tool for you.
What Is the Purpose of This App?
GlassesOn is a mobile app that helps you measure your eye numbers at home. It was built by 6over6 Vision Ltd. to make eye measurement simple, fast, and accessible for everyone.
People often need their glasses prescription to order new frames online. Visiting an eye doctor just for that can take time and money. GlassesOn solves this by letting you get key optical data from your phone.
The app does not provide a medical prescription. It gives you the numbers you need to order glasses online or set up AR/VR headsets without stepping out of your house.
How Does It Work?
How Computer Vision Technology Works
GlassesOn uses computer vision, a type of technology that allows a phone camera to analyze and extract data from images. The app takes a photo of your glasses and uses algorithms to calculate optical values from that image.
The magnetic card placed during the scan acts as a size reference. It helps the app calculate accurate distances and measurements from the photo. Without this reference, the measurements would not be precise.
What Equipment Do You Need?
For PD measurement, you only need your smartphone and a standard magnetic card like a debit card or library card. No extra tools or mirrors are required.
For full prescription extraction, you also need a flat computer screen between 12 and 27 inches and your current pair of glasses. The process is simple and takes only a few minutes.
Step by Step Scanning Process
Open the app and select what you want to measure. Hold the magnetic card against your forehead as instructed. The app uses voice prompts to guide you through each step clearly.
For glasses parameter extraction, place your glasses on the computer screen as directed. The app scans the lenses and extracts the optical data automatically. Results appear within minutes.
What Does It Measure?
Pupillary Distance (PD)
Pupillary Distance is the gap between the center of your two pupils. This measurement is essential when ordering glasses online. If the PD is wrong, the lenses will not align correctly with your eyes.
GlassesOn measures PD in under one minute. The accuracy is within 2 millimeters, which meets the standard required for ordering most types of eyewear online.
Sphere, Cylinder and Axis Explained
Sphere shows the overall power of the lens needed to correct your vision. A negative value means you are nearsighted, and a positive value means you are farsighted.
Cylinder measures astigmatism correction, and Axis tells where on the lens that correction should be applied. Together, these three values form the core of any glasses prescription.
How Accurate Is It?
GlassesOn follows ANSI Z80.17 accuracy standards. This means the Sphere, Cylinder, and Axis readings are accurate within 0.25 diopters. PD measurements are accurate within 2 millimeters.
The app has been listed as a Class 1 exempt medical device in relevant markets. It also holds CE approval in the EU, Health Canada recognition, and TGA registration in Australia. These approvals confirm that the app meets international measurement standards.
Results are most reliable when you follow the instructions carefully, use good lighting, and keep the magnetic card flat during scanning. Poor lighting or a shaky hand can reduce accuracy.
Who Should Use It And Who Should Not?
Ideal Users
This app works best for adults aged 18 and above who have stable single vision prescriptions. If your sphere power is between -6.00 and +3.00 and your cylinder is up to -2.50, the app is a good fit for you.
It is also useful for people who already know their prescription is stable and just need the numbers to order glasses online. VR or AR headset users who need their PD can also benefit from this app.
Who Should Avoid This App?
People who wear multifocal, bifocal, or progressive lenses should not use this app for prescription extraction. These lens types have multiple power zones that the app cannot scan correctly.
Anyone with prism correction in their prescription should also avoid using GlassesOn for Rx extraction. People with active eye conditions or those taking medication that affects vision should consult a doctor directly.
GlassesOn vs Eye Doctor Exam
| Feature | GlassesOn | Doctor |
| PD Measurement | Yes | Yes |
| Eye Health Check | No | Yes |
| Official Prescription | No | Yes |
| Disease Detection | No | Yes |
What App Can Do
The app quickly gives you PD and basic optical parameters for ordering eyewear online. It saves time and money when you just need numbers and already know your vision is stable.
What Only a Doctor Can Do
A licensed optometrist checks the full health of your eyes, not just the numbers. They can detect early signs of glaucoma, cataracts, retinal issues, and other conditions that an app simply cannot identify.
A doctor also provides an official prescription that is legally valid for purchasing glasses at any store. The app data is informational only and does not carry the same legal weight.
Why Did It Rebrand to The Framery?
GlassesOn was originally developed by 6over6 Vision Ltd. The app was later acquired by 1-800 CONTACTS, Inc., one of the largest contact lens retailers in the United States.
After the acquisition, the app was rebranded as The Framery. The new name aligns with the company’s broader eyewear shopping experience and allows users to save their measurements and connect them to online orders directly.
The core technology remains the same. If you used GlassesOn before, The Framery is the updated version of the same app with a cleaner design and additional features.
What Users Are Saying?
Most users praise the app for being easy to use and fast. Many mention that the voice-guided instructions make the process smooth even for first-time users. Several users confirmed that the PD results matched what their optician had measured.
Our team also tested the app to understand the overall user experience. Based on our experience, the scanning process feels simple, and the step-by-step guidance helps users complete measurements without much confusion.
Some users reported inconsistent results when they did the scan in low-light conditions. A few noted that the glasses scanning feature required more than one attempt before giving a clear reading.
Overall, the app holds a strong 4.9 out of 5 rating on the App Store with over 11,000 reviews. This reflects high satisfaction among users who use it for its intended purpose.
Pros and Cons

Cons

Important Things to Keep in Mind
Always use the app in a well-lit room. Bright and even lighting helps the camera capture clear images, which directly affects the accuracy of your results.
Use a plain magnetic card that has no sensitive information visible on the back. This keeps your personal data safe while still giving the app the calibration reference it needs.
Do not use the app results to change your prescription on your own. If your vision has changed or you have any eye discomfort, visit an eye doctor for a proper examination.
Final Verdict
GlassesOn, now The Framery, is a genuinely useful tool for a specific purpose. If you have a stable single vision prescription and need your PD or basic optical numbers to order glasses online, this app delivers exactly that quickly and for free.
It is not a replacement for a professional eye exam. Regular eye checkups are still important for your overall eye health. Think of this app as a convenience tool, not a medical service.
If you fit the eligible user profile, GlassesOn is worth trying. It saves time, costs nothing, and gives results that are accurate enough for online eyewear ordering.
