Our second-generation CES-award winning vision test, VisionCheck, is powered by MIT-patented technology to help you learn about your refractive error i.e. your nearsightedness, farsightedness, and astigmatism.

You can use the EyeQue VisionCheck app if you:
- Have a single vision prescription between +8.00 and -10.00
- Have a cylinder between 0 and -5.00
- Are ages 25 and older
- Want to track your vision

You should not use the EyeQue VisionCheck app if you:
- Have light sensitivity
- Are colorblind or have difficulty differentiating between red and green
- Require a prism measurement
- Have difficulty holding up a smartphone while navigating the smartphone screen
- Have a medical condition that affects your eyes or eyesight, including but not limited to glaucoma, age-related macular degeneration, diabetic retinopathy, or cataracts.

The VisionCheck uses MIT-patented Inverse Shack-Hartmann technology, which utilizes optical lenses combined with your smartphone’s pixel movement, to measure where the light focuses on the back of your retina. This means that to take a vision test, you’ll attach the VisionCheck to your phone, which will act a light source during the test, then take multiple measurements at different angles by merging a red and a green line into a solid yellow line.

*This is a self-administered vision test and results may vary. Our test performance feedback instantly lets you know how well you tested and provides resources to improve test performance.*
