The hassle that comes with the conventional way of determining your glasses prescription is pretty daunting. Also, the population of people that wear glasses worldwide makes it necessary to find more convenient ways to go about the process, and this is where the use of technology comes in. There are quite a few prescription scanner phone applications that do a decent job in providing users with their glasses prescription, although they differ based on the degree of reliability.

However, it is worth noting that these applications are not meant to replace eye specialist appointments; They have their limitations, i.e. an ophthalmologist or optometrist. So it will be better to set an appointment with your eye doctor if it has been a while since you did so. 

Some of the options for these applications include; 

• Prescription Lens Scanner by SmartBuyGlasses USA.
• Eyeglass Prescription Scanner by Lensabl.
• GlassesUSA Prescription Scanner.
• Lingo RX Reader.
• GlassesOn app.

Let us go through one of these options, the GlassesUSA prescription scanner app. But first, go through the following steps to find out how it works:

• It uses your smartphone camera to scan the current prescription of your glasses.
• It requires you to upload a selfie picture to measure your pupillary distance.
• First, you need to download the application from the official website or on your smartphone from the App Store for iPhone users and and the Play Store for android users.
• Once you’ve downloaded the app, open it and click start scan. It uses voice prompts to take you from one step to another.
• To continue, you’ll need a computer with a screen measuring 12” x 27”.
• You’ll also need your current eyeglass.
• A standard magnetic card for scaling (Magnetic stripe cards are cards that use magnetic labels to transmit financial information to the card issuer), be sure not to use something with sensitive information on it.

• The next step is to set up and calibrate, and this works by scanning a QR code after logging in to an address you’ll receive on your laptop, which also allows you to sync your phone to your computer. Once the code is scanned, you’ll then scale the exact size of your computer screen using a magnetic card. You’ll need to exercise patience because it may take several tries before calibrating successfully. If you experience any delay, you’ll have to hold the card flat against the screen. Adjusting the screen back and forth should also help. 

• Once you’ve completed the setup explained in the bullet points above, it’s time to scan your glasses. You do this by placing your glasses between your phone and computer. You’ll be required to tilt your eyeglasses for approximately three minutes until they read correctly.

• The next step is measuring your pupillary distance(PD) by snapping a selfie with the magnetic card between your eyebrows, which enables your eyewear's lens power to be centered correctly.
