*The percentage loss in aphakic scotopic sensitivity is the same as the percentage gain in blue-green phototoxicity protection (rhodopsin mediates both processes). | |||||||||
†The percentage of optical radiation in a particular wavelength range that is blocked: UV (350–400 nm), violet (400–440 nm), blue (440–500 nm), and green (500–570 nm). | |||||||||
‡Hypothetical violet blocking high pass filters that block all optical radiation below but transmit 99% of radiation above the specified cut-off wavelength. | |||||||||
