The GlassesOn App – Try, Buy & Explore Glasses Easily is a helpful mobile app that makes dealing with eyeglasses simple and fun. Many people find buying new glasses hard because they worry about the right fit, prescription, or how the frames look on their face. GlassesOn solves these problems with smart technology right on your phone.
This app comes from 6over6 Vision, a company focused on making vision care easy and affordable for everyone. It uses advanced computer vision (like smart camera tricks) to help you measure important things and even check your current glasses. The app has high ratings, around 4.8 stars on both Apple and Google stores, with many happy users saying it saved them time and money.
In this article, we will look at what the GlassesOn app does, how it works step by step, its main benefits, who should use it, and why it stands out. We will keep everything clear and simple so you can understand fast.
What Is the GlassesOn App?
GlassesOn is a free mobile app for iPhone and Android phones. Its main job is to help you get key details about your eyes and glasses without always going to an eye doctor or using old tools like rulers.
The app has two big features:
- It measures your Pupillary Distance (PD) very quickly – often in under one minute.
- It scans your current pair of glasses to pull out your full prescription details, like sphere (power), cylinder (for astigmatism), axis, and PD.
This info is super useful when you want to buy new glasses online. Many online stores need your PD and prescription to make glasses that fit perfectly. Without them, your new glasses might feel wrong or cause headaches.
The app is listed as a medical-grade tool. It has approvals from bodies like the FDA (in the US as a Class 1 exempt device), CE (in Europe), and TGA (in Australia). This means it meets safety and accuracy rules for this kind of tool.
Note: The app is not a full eye exam. It does not check for eye diseases or give new prescriptions if your vision has changed. Always see an eye doctor regularly for full eye health checks.
How Does GlassesOn Work? Step-by-Step Guide
The app is easy to use, even if you are not good with phones. Here is how it works for the two main parts.
Measuring Your PD (Pupillary Distance):
PD is the distance between the centers of your two pupils. It is very important for glasses to line up correctly with your eyes.
- Download the app from the App Store or Google Play.
- Open it and tap “Start PD” on the home screen.
- You need a standard card with a magnetic strip (like a library card, credit card, or similar). Light-colored cards work best.
- Follow the voice instructions. The app talks to you!
- Hold the card near your face and look at the camera.
- The app uses your phone’s camera and smart tech to measure in seconds.
- You get your PD number right away – often very accurate.
Many users say this is faster and more reliable than using a mirror and ruler. Some reviews call it the #1 app for PD measurement.
Scanning Your Current Glasses for Prescription Details:
This feature is great if you have old glasses and want the same power in new ones (for example, for sunglasses or spares).
- You need a computer or laptop screen (size 12 to 27 inches) and your phone.
- Sync the app with your screen (it guides you).
- Place your glasses in front of the screen as told.
- Use a card again for scale.
- Follow the voice and on-screen steps – it takes about 10 minutes.
- The app scans the lenses using computer vision.
- It gives you numbers like:
- Sphere (SPH) – the main power.
- Cylinder (CYL) and Axis – for astigmatism.
- PD again.
The results match industry standards, say users. One person shared: “This thing nailed my Rx EXACTLY.”
After you get the details, the app lets you use them to shop for new glasses online easily.
Why Use GlassesOn? Key Benefits

Here are the top reasons people love this app:
- Save Time and Money – No need to visit an optician just for PD or to read your old prescription. Do it at home anytime.
- Easy for Online Shopping – Many sites like Zenni, GlassesUSA, or others need PD. With GlassesOn, you can order with confidence.
- Helpful for AR/VR Headsets – Some VR glasses need accurate PD too. The app gives that quickly.
- High Accuracy – Clinically tested and approved by health groups. Users report it matches what eye doctors measure.
- Free Basic Use – PD measurement is free. Scanning glasses may have options, but core features are easy to access.
- User-Friendly – Voice instructions make it simple. No hard steps.
- Privacy Safe – The company has a clear privacy policy. They respect your data.
Compared to other apps or tools:
- Some virtual try-on apps (like Warby Parker or Zenni) let you see frames on your face, but they do not give prescription scans or PD as accurately.
- GlassesOn focuses on the technical side (PD and Rx details), which helps when buying from any store.
- It is not a full virtual try-on for new frames in the app itself (some related tools like GlassOn.io do that for stores), but it pairs well with shopping sites.
Who Should Try the GlassesOn App?
This app is perfect for you if:
- You already wear glasses and want spares, sunglasses, or updates.
- You shop for glasses online and need PD or prescription info.
- You hate going to stores or waiting for appointments just for measurements.
- You are 18 or older with stable vision (the app says this for best results).
- You want to try something new and tech-based for eye care.
It may not be for:
- People getting their first eye exam – see a doctor first!
- Those with big vision changes recently.
- Anyone who wants a full eye health check.
Tips for Best Results with GlassesOn
- Use good lighting – not too dark or bright.
- Hold your phone steady.
- Follow voice instructions carefully.
- Use a plain magnetic card.
- If it does not work first time, try again – many say it gets perfect on the second try.
