1 Scope
This part of GB 10810 specifies the requirements for transmittance properties of spectacle lenses and relevant spectacle products made of any material. This part is applicable to relevant spectacle products, including: mounted spectacle lenses, completed sunglass, sunglass lenses, driving spectacles, polarizing spectacles, gradient-tinted spectacles and photochromic spectacles, etc.
This part is not applicable to:
——Spectacle lenses with special transmission or absorption properties used for medical purpose.
Note: The requirements for the optical and geometrical properties of spectacle products are already given in national standards such as GB 10810.1, GB 13511 and "Ophthalmic Optics-Spectacle Lenses-Fundamental Requirements for Uncut Finished Lenses" (equivalent to ISO 14889).

3 Terms and Definitions
For the purpose of this part of GB 10810, the following terms and definitions apply.
3.1
Visible radiation
Any optical radiation capable of directly causing a visual sensation.
There are no precise limits for the spectral range of visible radiation, since they depend upon both the amount of radiant power and the responsivity of the observer.
In the field of ophthalmic optics, the wavelength range of visible radiation is limited between (380~780)nm.
