The effects of size and analysis method on the performance of the Farnsworth-Munsell D-15 test

摘要: On the basis that dichromats function as anomalous trichromats when undertaking large-field colour vision tasks, it has been suggested will perform better on a D-15 than standard D-15. The technique of Vingrys and King-Smith was used to provide multi-factorial analysis plots. When angular subtense task exceeds 4°, is also necessary use CIE 1964 Supplementary Standard Observer calculate chromaticity co-ordinates by which assess performance. (7× linear increase) tests were administered 17 protanopes 21 deuteranopes. results analysed in terms distance travelled Luv space method King-Smith. data using chromaticities calculated for 1931 Observers.
