The Sheridan Gardiner Test Complete contains near vision, distance and reduced Snellen tests which are all based on shape-matching. Although originally designed for young children, these tests are equally suitable for other groups such as illiterates, the disabled, those with learning disabilities or where a language/communication barrier exists. Results are more reliable than those obtained with illiterate E tests. The reading test has print sizes ranging from N5 to N48 and includes a reduced Snellen Chart for use at 33cm.
