EyeQue Refractive Measurements (ERM) are the final output from the Personal Vision Tracker or VisionCheck, and expressed using the same type of terminology and layout as a professional prescription so that you can easily compare the ERMs and your current prescription.
An example of an ERM record looks like:
| Spherical | Cylindrical | Axis (degrees) | |
| OD (Right) | -2.50 | -.075D | 30 |
| OS (Left | -2.00 | -1.25D | 180 |
| PD: 68 | NV ADD +2.00 |
