The EyeQue vision test gives you your Spherical Equivalent (SE) refractive error after each test. Using the full Test mode you will be ready to receive your EyeGlass Numbers. These are a set of numbers that contain parameters defining refractive error needed for ordering eye glasses.
An example of an EyeGlass Number record looks like:
|PD:||NV Add +2.00|
The EyeGlass Numbers may seem familiar to you because they are written in the same format as your eye doctor's prescriptions. Note that Cylinders are expressed in negative Cylinder notation.
- Spherical & Cylindrical values are measured in Diopters and represent components of your Refraction Correction
- Axis represents the angle of the Cylindrical component makes with respect to an imaginary horizontal line through your eye.
- PD corresponds to the Pupilary Distance in millimeters (mm). This is the distance between your two eyes.
- NV ADD is called the near vision add and is needed for persons with Presbyopia.
