Abstract

L'invention concerne une lentille ophtalmique multifocale offrant une vision de loin, intermédiaire et de près ainsi qu'une profondeur de champ améliorée. Selon de multiples modes de réalisation, les lentilles EDOF divulguées réduisent au minimum les phénomènes photiques indésirables, permettent une vision de loin et intermédiaire continue, avec un champ visuel favorisant une vision de loin plutôt que des pics d'intensité étroits isolés, et s'adaptent à différentes tailles de pupille, ces modes de réalisation divulguant des lentilles avec des additions supérieures à 2D, qui permettent d'ajuster la courbe d'addition, et assurent une vision de loin nette dans différentes conditions d'éclairage, avec des structures de déphasage d'une hauteur relativement faible.
