The lanterns in current use are the Farnsworth lantern, now superseded by the Optec 900, <br />the Holmes Wright Type A and B lantern and the Beyne lantern (figure 28). <br />Lantern tests are usually failed by dichromats and anomalous trichromats whose defect is severe <br />enough to cause them to fail the Farnsworth D15 test but the ability to recognise small coloured <br />signal lights can vary quite widely among those with mild anomalous trichromasy. A pass at the <br />D15 test or a small range at the anomaloscope does not necessarily mean that signal light colours <br />can be recognised (Cole and Maddocks, 1998). <br />Fimtre 28.
