At-home vision testing, powered by your smartphone

•Check your eyes whenever, wherever • Measure your pupillary distance (PD) • Order glasses online with your results • Track your vision with personalized

VIE VisionCheck is a refractometer that measures your refractive error, i.e. your nearsightedness, farsightedness, and astigmatism. The tests show results in the same format as your prescription, allowing you to order glasses online. The results will also include your estimated near-vision add (NV ADD+), needed to purchase reading or progressive glasses. The VisionCheck includes a patent-pending pupillary distance (PD) measurement tool, called the PDCheck, that accurately captures your PD in a matter of seconds.

Save time: Unlike traditional office visits that you make once a year, you can use the VIE VisionCheck anywhere, anytime. All you need is a smartphone and an active internet connection. No need to schedule ahead, drive through traffic, and wait at the office only to sit through boring lectures or sales spiels. In comparison, each VisionCheck test takes about 5 minutes to complete once you understand the process. Most first-time users get great results after taking 3 or 4 tests, usually under 30 minutes in total. VIE is hassle free and gives back hours of your valuable time.

More accurate than a single point-in-time refraction test: Since your vision fluctuates throughout the day, taking multiple tests at different times of the day gives a better average refraction than a one-time refraction test during an office visit. Especially if someone is having a bad day! The MIT-patented technology powering the VisionCheck has been extensively tested with over 12,000 users over the past 2 years and has been optimized to give excellent refraction values for ordering

Real tests, real results: Unlike other online vision tests, VisionCheck gives you a true refraction measurement. These results are called "EyeGlass Numbers" (EGNs). We do not simply request and renew your prescription. VIE products ACTUALLY test your vision and generate real scientific results. Also, there's no wait time; you get refraction results (EGNs) immediately after you complete three refraction tests.

See your data, use your data: Your personalized dashboard can be accessed through your VIE account and contains a multitude of information about your vision. This includes detailed reports showing and explaining your results, as well as the consistency of your testing. The report even compares your vision results with the general VIE population! Use your most updated EyeGlass Numbers (EGNs) to order glasses online from trusted retailers or share them with your eye care provider.

Safe & robust: VisionCheck uses only the illumination from your smartphone screen, filtering the light making it completely safe for your eyes. The VisionCheck device is rugged yet beautifully designed. Internal elements of the device are enclosed in a solid injection molded plastic housing while the precision optics are made from the highest grade polymers; the electronic components are commercially approved as well. VisionCheck has undergone extensive environmental testing including drop, temperature, humidity, and shock tests to ensure that it is safe and robust enough for household use. VisionCheck is registered with the FDA as well.

Fun and easy to use: Simply launch the app, attach the VisionCheck device, and use the touch sensor buttons to perform a series of game-like actions to overlap the red and green lines as you look through the device. Voila, you get your refraction results in the form of EyeGlass Numbers, instantly. Voice guidance is also available, making it even easier to use.

We are mindful of your privacy and security. We use HIPAA compliant processes and cloud storage for all your EGNs and personal data. We do not share your information with any organizations for any purposes, EVER.

What's inside? Below is an “exploded view” of the patented VisionCheck device. It is a precision optical instrument built with micron-level tolerances. Substantial engineering effort was required in order to build reliable devices on a mass scale. To achieve that, we have employed a team of exceptional industrial designers, mechanical, electrical, optical, and firmware engineers.
