Sehzeichen, auch Optotypen genannt, sind Buchstaben, Zahlen, Bilder oder Symbole, die der Ermittlung der Sehschärfe dienen. Die Strichstärke der Sehzeichen ist so bemessen, dass sie in der für Sehschärfe 1 vorgesehenen Reihe dem Auge unter einem Winkel von 1 Bogenminute erscheint. Als genormtes DIN-Sehzeichen gilt der Landoltring. Weitere Sehzeichen sind der Snellen-Haken, der häufig für die Untersuchung von Kindern verwendet wird, und die Sehprobentafeln. Zudem wird bei Prüfungen des Nahvisus häufig eine Texttafel mit Fließtext unterschiedlicher Schriftgrössen verwendet, zum Beispiel sogenannte Nieden-Leseproben.
