It was developed by the Swiss-born ophthalmologist Edmund Landolt.The Landolt C consists of a ring that has a gap, thus looking similar to the letter C. The gap can be at various positions (usually left, right, bottom, top and the 45° positions in between) and the task of the tested person is to decide on which side the gap is. The size of the C and its gap are reduced until the subject makes a specified rate of errors. The minimum perceivable angle of the gap is taken as measure of the visual acuity. It is generally practiced in the laboratory.The stroke width is 1/5 of the diameter, and the gap width is the same. This is identical to the letter C from a Snellen chart. The Landolt C is the standard optotype for acuity measurement in most European countries. ★★★ Landolt C test 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) Landolt C test chart HD - Care about your eyes!
