I think it would be a good idea for this chart to include the vision distances for rows 9, 10, and 11. This would allow people to see that it is possible to be categorized as having better than 20/20 vision. JVDnh3 14:19, 2 June 2011 (UTC)
I think it would be a good idea to show the dots per inch (or pixels per cm) of the image. Something like "Viewed or printed at {90,200,300} ppi the image will be X by Y {cm,m,inches, ...}. Common LCD monitor's pixels per inch are 90ppi making this image {smaller,larger} than it should be. — Preceding unsigned comment added by 182.239.165.14 (talk) 06:45, 21 August 2011 (UTC)
