The EyeQue VisionCheck app and device allow you to test your vision conveniently from the comfort of your own home. Developed by EyeQue Corporation, this free app requires the EyeQue VisionCheck device to accurately measure your refractive error, including nearsightedness, farsightedness, and astigmatism.

To use the EyeQue VisionCheck app, you must have a single vision prescription between +8.00 and, a cylinder between 0 and -5.00, and be 25 years or older. This app is perfect for those who want to track their vision over time.

Using MIT-patented Inverse Shack-Hartmann technology, the VisionCheck device attaches to your iPhone and utilizes optical lenses to measure the focus of light on the back of your retina. During the vision test, a red and green line are merged into a solid yellow line to measure multiple points of focus at different angles.

Please note that this is a self-administered vision test, and individual results may vary. The app provides instant feedback on test performance and offers resources to improve accuracy. Rest assured, EyeQue Corporation takes your privacy seriously and does not share your information with third parties.
