An electro-active lens (100, 200, 300) that may include first (110, 115, 120, 122, 125) and second (135, 137, 140, 145, 150) electro-active cells, having controlled birefringence (e.g. a Nematic liquid crystal) the cells being adjacent to and stacked upon each other and, when in a resting state, oriented orthogonal to each other to reduce birefringence.
L'invention concerne une lentille électro-active (100, 200, 300) pouvant comprendre une première (110, 115, 120, 122, 125) et une seconde (135, 137, 140, 145, 150) cellule électro-active, et présentant une biréfringence régulée (cristal liquide nématique, par exemple), lesdites cellules étant adjacentes et empilées l'une sur l'autre. En outre, à l'état de repos, ces cellules sont orientées perpendiculairement l'une par rapport à l'autre, d'où une biréfringence réduite.
