EyeQue products uniquely combine time-honored and tested methods with technological advancements to bring convenience to vision testing. The products are specifically designed to capture information about the visual system and bring awareness to the importance of caring for our eyes, in the most convenient fashion. The Personal Vision Tracker, the first of two devices, measures an individual’s refractive status, including near-or-farsightedness and astigmatism. The second device, the EyeQue Insight, provides a measurement of visual acuity or the sharpness of vision. Both of the EyeQue products are based on instruments and charts used in vision testing for many years.
If you’ve ever been to an eye doctor, chances are you were tested with an autorefractor that measures your prescription for glasses. During the auto-refraction, most people see either a barn house or a hot air balloon that sharpens then fades away. Autorefraction is several decades old and works by shining invisible infrared light into the eye, measuring the reflection as it bounces off the back of the eye. Several measurements of these reflections are used to determine when the eye is properly focused. Similarly, the Personal Vision Tracker uses the same technology within an optical miniscope attached to a smartphone to capture these reflections. Instead of automatically refracting your eyes (auto-refractor) with the invisible infrared, the EyeQue Personal Vision Tracker uses a manual process that asks the user to “overlap lines”, which reverse-calculates the level of refractive error in the eye. While the process is different, the resulting measurements are very similar. More tests on the Personal Vision Tracker leads to higher quality and more accurate results, which can be used to order glasses online.
One of the most iconic medical equipment of all times, the Snellen Eye Chart is something we’ve all seen at one point during an annual physical, school screening or at our eye doctor’s office. Standing about 20 feet from the chart (or optically created 20-foot distance), the tester is asked to cover one eye and read the smallest line of letters we could identify. You may have also encountered other types of vision charts such as LEA symbols, Tumbling E, or numbers but all measure the same thing, Visual Acuity, or how clearly and sharply we can see. The Insight employs a binocular viewing device attached to a smartphone and presents a chart of randomly rotated “E” optotypes (figures or letters of different sizes).
The viewer is asked to swipe the smartphone screen in the direction of the opening of the “E”. Just like the traditional vision testing, it measures each eye separately and then together, revealing the visual acuity on the smartphone screen upon completion. The resulting measurement is seen as 20/20, 20/40, etc.
