 A - 2

· Trial Lens Data

The data where the selected value (or the latest value when the selected value has not been obtained) is examined
and indicated by the cylinder mode (cylinder reading direction), which would make the sphere trial lens have
lower power for convenience.

· Vertex Distance

The distance between the corneal vertex to the posterior surface of the spectacle lens.
