You can join in either in real life or via our live streaming facility or download the recorded and edited version at later point at your convenience. The upcoming Training on CIE 203-2012: A Computerized Approach to Transmission and Absorption Characteristics of the Human Eye will take place on
Wednesday, September 5, 2012 between 09:00am and 04:00pm in Vienna at the CIE Central Bureau and will be chaired by Dr D Jack Lund.
Brief Outline:
  • Overview of the structure of the eye
  • Methods of measuring the spectral transmittance of the pre-retinal ocular media
  • Direct transmittance vs total transmittance of the pre-retinal ocular media
  • The data from which the spectral transmittance of the rhesus and young human eye are derived
  • A discussion of the tabulated data included in CIE 203-2012
  • The aging human eye and the changes in preretinal ocular media with age
  • The equations describing the optical density of the aging human eye as derived by van de Kraats and van Norren (2006)
  • Brief overview of the structure of the retina
  • Retinal absorbers and action spectra for light–induced retinal effects.
Registration will open as of July 1, 2012. Click here for participation in real-life or choose our live streaming facility which is readily available via this link.
Please, note: places are limited and will be assigned on a first come, first serve basis. Registration for both, real-life and live streaming, is open till Monday, August 20, 2012.
