Astigmatism Simulator

See how uncorrected astigmatism smears an eye chart along one meridian, and how the blur direction follows the axis. Educational illustration only — it does not represent any individual patient's vision and is not a diagnostic tool. More conditions: combined vision simulator.

Simulates astigmatism in one meridian (e.g., simple myopic astigmatism). In minus cyl, blur is 90 degrees perpendicular to the axis and in plus cyl blur is on the same meridian as the axis.
