what is the angle () of the openings in those c-shapes for a 6/6 viewer?
IOW; What is the angular resolution defining a 6/6 visual acuity?

- I assume one arc minute, same as for Snellen charts. --Random832 (contribs) 18:55, 27 May 2008 (UTC)
According to Russian textbooks on Ophthalmology, the gap can be seen at angle of one angular minute at the distance of seven meters. The "picture" of the gap on retina, created by lens, covering the area of one light receptor. —Preceding unsigned comment added by 184.108.40.206 (talk) 13:51, 18 January 2010 (UTC)
And what's wrong with that picture? I'm using Firefox 220.127.116.11 and no image appears... - Nmnogueira 15:37, 29 August 2007 (UTC)

Representation of Landolt C is inaccurate
Please note that the diagram https://en.wikipedia.org/wiki/File:Landolt_C.svg of the Landolt ring is rather inaccurate. As correctly stated in https://en.wikipedia.org/wiki/Landolt_C the width of the gap should be 1/5th of the diameter of the C reps. the stroke width of the C. In this diagram the gap clearly is too small.AlbertJanPool (talk) 08:45, 5 November 2013 (UTC)
