Just a crease: you need to know your recipe. Of course, you can call your optician to get the numbers – unless the office is closed. Or you just feel weird if you ask, because they know you're shopping elsewhere .
Luckily, if you have a pretty simple recipe (that is, they're not bifocal, progressive or cola glasses) there's a free tool from GlassesUSA.com that lets you scan your current glasses. I shot it with my son's glasses and the results corresponded to the current prescription.
And according to GlassesUSA.com, the results correspond to "the standard deviation range as in any medical practice" – although this is not intended to take the place of an eye exam. In fact, it may make sense to make an appointment if you have not reviewed your vision in a year or more.
However, if you want to quickly and easily find out what kind of lenses you have, do the following:
Step 1: Take your current glasses, your smartphone, and a credit card (or any other plastic card the size of a credit card – it's used to calibrate the app, not to pay). Then stand in front of your computer and point your browser at www.glassesusa.com/scan. [19659006[19459018[Step2: Enter your phone number or email address to receive a link for the GlassesUSA -App to get.
Step 3: After installing the app, follow the instructions. You must first scan a screen QR code, then hold the credit card on the screen and scan it. From there, hold your glasses for different readings between the phone and the screen. It ends with a pupillary distance scan (PD), in which you have to hold the card amusingly to the forehead.
It's a pretty straightforward process that takes about 10 minutes. When you're done, you'll be asked to create a GlassesUSA.com account. From now on, you should see your recipe immediately.
And that was & # 39; s! With this data, you can order lenses and sockets from anywhere. Just keep in mind that the app does not store any of this information. If you would like to retrieve it later, you will need to sign in to your GlassesUSA.com account again in a browser.
