3 Terms and Definitions
For the purpose of this Standard, the following terms and definitions apply.
3.1
Contact Lenses
Note. The definition of contact lenses includes the myopic lenses, hyperopia lenses and trial (diagnostic)
lenses.
3.2
Rigid Gas Permeable Contact Lenses
The contact lenses made of rigid gas permeable material, usually the polymeric material used for
contact lenses contains the organic silicone and organic fluorine.
3.3
Rigid Gas Permeable Contact Lenses for Orthokeratology
The rigid gas permeable contact lenses for orthokeratology (hereinafter referred to as orthokeratology
therapy in order to change the shape of cornea.
3.4
Oxygen Permeability (Dk value)
Arithmetic product of the gas dissolution coefficient and the diffusion coefficient.
Note 1. This is one of the most commonly used parameters of materials of the contact lenses.
Note 2. Unit in or . The Dk value
obtained through the hPa is multiplied by 1.333 22, to get the Dk value in unit of mmhg.
Note 3. Oxygen Permeability Coefficient. oxygen flux of the contact lens material of the unit-thickness, under certain
conditions and under the unit gas pressure difference.
Oxygen Permeability Coefficient = ----------------------------------------------------------------------
Area (cm2) X Time (s) X Pressure Difference (hPa)
3.5
Oxygen Transmissibility (Dk/t value)
The oxygen permeability coefficient divided by the average thickness of the measured material.
3.6
