VisionCheck is a self-administered test so results vary based on your ability to take consistent, precise tests. VisionCheck is an optical device powered by MIT patented technology that measures and provides EyeGlass Numbers; the corrective power for:
- Spherical (nearsightedness, farsightedness)
- Cylindrical and Axis (astigmatism)
- NV ADD+ (reading vision for bifocals and progressives)
- Pupillary distance (PD) via the PDCheck tool
The margin of error for spherical and cylindrical measurements are within +/-0.25 diopters. The margin of error for pupillary distance is within 1mm. It is important to conduct the self-administered test correctly to get the best results.
Our community of testers have provided hundreds of testimonials, many touting the accuracy of their results testing refraction with EyeQue. Read some of those here.
