A Snellen chart is an eye chart used by eye care professionals and others to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Hermann Snellen who developed the chart during 1862. The traditional Snellen chart is printed with eleven lines of block letters. The first line consists of one very large letter, which may be one of several letters, for example E, H, or N. Subsequent rows have increasing numbers of letters that decrease in size. A person taking the test covers one eye, and reads aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the visual acuity in that eye. ★★★ Snellen chart HD FEATURES★★★ - Not entertainment app - professional medical tool! - HD iPad graphics - Correct distance instructions for test - Only useful professional tests - New FREE updates is upcoming! - Full iPad and iPad 2 support - Support for use with iPad VGA adapter with you monitor/TV/projector/etc. (c) Snellen chart HD - Care about your eyes!
