note[edit]

"It has been suggested that Optotype be merged into this article or section. Proposed since May 2010." I agree with this. Optotype is more a definition than a topic.Bstephens393 (talk) 17:36, 7 June 2011 (UTC)[reply]

File:Snellen chart.svg[edit]

1. The ".svg" format is not as universal as would be ".tif" or ".pdf" or even ".jpg" (which is not really appropriate for this image). For instance, Windows XP Picture & Fax viewer and IRFAN do not display this format.

2. Since the whole point of the image is size, it should be self-checking. For instance, a border could be added with fine print saying the border size is A x B mm, or a legend could give the height of the largest E in mm. Most formats (including svg) do contain the original resolution, so display software can say "100% view", but printing frequently shrinks or expands images.23.24.37.125 (talk) 18:12, 25 June 2020 (UTC)[reply]
