Even though both the Personal Vision Tracker and VisoinCheck work well when used properly, EyeQue cannot directly monitor the way a user takes a test. Therefore, we cannot guarantee the quality of the vision test results and the derived EyeGlass Numbers. Also, we do not guarantee that the EyeGlass Numbers are able to be used directly to order vision-corrective eyeglasses or other corrective eyewear. EyeQue does keep track of certain test metrics such as speed and consistency. EyeQue also rates the statistical quality of each set of results in the backend. Keep in mind that there is no absolute correct value for refractive errors. Even two optometrists will often come to different results when examining the same patient.
As of versions 2.1 of the Personal Vision Tracker and 2.0 of the VisionCheck app, EyeGlass Numbers that are verified inconsistent by our algorithms will no longer be displayed to the user. Only those EyeGlass Numbers that have high consistency will be shown to the user. You can view individual test results by tapping on the "individual tests" icon on the dashboard. This will provide the user insight into what tests are considered inconsistent. A red X will indicate that the test is inconsistent, while a green check mark will show that it is consistent. Be mindful that these are not EGNs, but test results only and not a measurement of your eyes.
