EyeGlass Numbers (EGN) are generated when your completed vision tests result in a high confidence level based on consistency and accuracy. If there is too much variation in your tests, an EGN will not be displayed. To check if you have any inconsistent tests, you can access the "individual test" button in your app's dashboard. If a test is inconsistent it will be highlighted in red. Keep in mind that as you take more vision tests you will become faster and more consistent; it takes a few rounds of practice to master. We recommend that you take the Practice Test until you feel you are comfortable with taking the tests in general.
Also, if you did not mark the box indicating that you removed your glasses or contacts (prior to testing), the EyeQue PVT and EyeQue VisionCheck app will assume you are still wearing your corrective lenses and the results from these tests will not be included in the calculation of your EGN.
Last, please be aware that the device just might not work for you and that's OK. Some will not be able to complete the tests or have issues while taking it. If you cannot see the pattern on the vision test due to small pupils, amblyopia, and visual field detects the device will not work for you. Some will have trouble relaxing their eyes' natural focusing system leading to some highly inaccurate vision test results. We do not recommend the Personal Vision Tracker or VisionCheck to those with medical conditions affecting their eyes and eyesight. If the device does not work for you and you are within the refund policy, please contact email@example.com to start the return process of the miniscope.
