Acuity is represented as a fraction, with the distance at which you are standing being the numerator (top part of fraction), and the normal maximum legible viewing distance (\"Distance\" on the chart below) as the denominator (bottom of fraction). So if, at 20 feet, you can read the letters on the row marked “40,” this means you have visual acuity of 20/40 or better: 1/2 normal. From 10 feet, if the smallest letters you could read were on the “40” line, this would give you an acuity of 10/40: 1/4 normal. If you are nearsighted, your vision will become more normal the closer you stand to the chart.\nMake your own eye chart!\nFor those enterprising souls out there who would like to laser print or draw by hand their own eye chart, or if you would like to verify that your printout is of the correct proportions, here are the specs:\nDistance (feet)  70   60    50    40    30    20    15    10    7    4\nletter ht (mm)   31   27    22    18    13     9     7     4    3    2\nletter ht (pt)   88   76    63    50    38    25    19    13    9    5\nfont size (pt)  152  130   108    87    65    43    33    21   15    9\nInterpreting the chart\n“Distance” in the above table refers to the furthest distance from the chart at which a normal eye is able to read the letter. On a Snellen eye chart, row’s letters of a given size have the corresponding distance number next to them. Thus, row of 18mm letters is marked “40.” The font must be Courier (or Courier Bold) in order for the \"font size\" in points to correspond to the indicated letter height. Courier Bold is the PostScript font that most closely approximates the official Snellen letters.\nNote: the top of the second page of the eye chart will need to be taped to the bottom of the first page of the eye chart (at the dotted line). Be sure to cover the dotted line with your paper.\nSource: International Society for the Enhancement of Eyesight, January 28, 2005, \u0013 HYPERLINK \"http://www.i-see.org/\" \u0014http://www.i-see.org/\u0015, accessed May 30, 2006.\u000f\n70\t\t \tA B\n60\t    G H S\n50  O Q I J\n40 T R V M X\nR D E F I L\nTape here ↑\u000f\n20  R X J B T I F P A\n15  I R G H J D S E U O Q X\n10     H N M K L D R T Y E W I O Q P R E\n7       F D R T K S W Q I V D H K I U T X S B K D F E\n4 \t\t                B O F C P T E B L F B E Z C O P E","cbCaim05LrUCrFyd","https://ap.wps.com/l/cbCaim05LrUCrFyd","doc",32768,"English","# Using a Snellen Eye Chart\n## Make Your Own Eye Chart\n## Interpreting the Chart","[{\"question\":\"How is visual acuity measured on a Snellen eye chart?\",\"answer\":\"Visual acuity is expressed as a fraction: the testing distance is the numerator, and the normal maximum legible distance for the correctly read row is the denominator.\"},{\"question\":\"What font is required for the chart proportions to match the letter heights?\",\"answer\":\"The font must be Courier (or Courier Bold) so the point-based font size corresponds to the indicated letter height.\"},{\"question\":\"How do you assemble a multi-page eye chart?\",\"answer\":\"Tape the top of the second page to the bottom of the first page at the dotted line, and cover the dotted line with paper.\"}]","Eye Chart Diagram Template - Free Download | DOC",1788295588]
