6.2 List of Terms and Abbreviations
The following terms and abbreviations are used in reference to the device and in the Operator’s Man-
ual.
Terms
SE Spherical equivalent refractive power
SPH (S) Spherical power
CYL (C) Cylindrical power
AXIS (A) Cylinder axis
ADD Addition power
PRISM Prism power (indicated with BI/O, BU/D, or ∆θ )
UV Ultraviolet
UV-A Ultraviolet A (wavelength: 315 to 380 nm)
Reference wavelength Mercury e-line 546.07 nm and helium d-line 587.56 nm
Abbe number Measure for chromatic dispersion of optical glasses
Progressive power lens Multifocal lens with addition power for near vision added to its lower
portion based on distance vision dioptric power
Because the dioptric power gradually changes from distance to near
portions of the lens, intermediate vision correction is also available.
