Abstract
A spectacle lens supply system and a related technology thereof including a spectral transmittance setting unit that sets a spectral transmittance of a spectacle lens from a solar radiant intensity in a region where the spectacle lens is used and a spectral transmittance of an eye of a wearer of the spectacle lens on a basis of a relationship selected from at least one of relationships 1 to 3.
Claims18
A spectacle lens supply system comprising a spectral transmittance setting unit that sets a spectral transmittance of a spectacle lens from a solar radiant intensity in a region where the spectacle lens is used and a spectral transmittance of an eye of a wearer of the spectacle lens on a basis of a relationship selected from at least one of relationships listed below:
- (1) A relationship 1 between a wavelength of light and an irradiance for determining whether or not to cause a morphological change of ocular cells according to a degree 1 required for a morphological change of ocular cells of a wearer of a spectacle lens
- (2) A relationship 2 between a wavelength of light and an irradiance for determining whether or not to cause a change in migration of ocular cells according to a degree 2 required for migration of ocular cells of a wearer of a spectacle lens
- (3) A relationship 3 between a wavelength of light and an irradiance for determining whether or not to cause a change in invasiveness of ocular cells according to a degree 3 required for invasiveness of ocular cells of a wearer of a spectacle lens.
A spectacle lens supply method comprising a spectral transmittance setting process of setting a spectral transmittance of a spectacle lens from a solar radiant intensity in a region where the spectacle lens is used and a spectral transmittance of an eye of a wearer of the spectacle lens on a basis of a relationship selected from at least one of relationships listed below:
