The invention relates to an apparatus (100) for the performance of optometric measurements, said apparatus (100) comprising: - an opto-adjustable lens (11) whose optical power is adjustable, said lens being governed by a periodic signal configured to produce a optical power wave (200) periodic in time; - means (12) for the adjustment of the mean value of the periodic optical power wave (200); characterised in that the apparatus (100) further comprises: - an optical projector system (20) to project a plane from the opto-adjustable lens (11) onto a plane external to the apparatus (100); and in that – the periodic signal has an amplitude such that it produces an amplitude of the periodic optical power wave (200) corresponding to a chromatic difference of focus between a first wavelength and a second wavelength of visible light which crosses the opto-adjustable lens (11). The invention likewise relates to a system for the performance of optometric measurements, and a method for the adjustment of the optical power of an adjustable lens. [EN]
La invención se refiere a un aparato (100) para realizar medidas optométricas, comprendiendo el aparato(100): - una lente optoajustable (11) cuya potencia óptica es ajustable, estando dicha lente gobernadapor una señal periódica configurada para produciruna onda de potencia ópticaperiódica (200) en el tiempo; - medios (12) para ajustar el valor medio de la onda de potencia óptica periódica (200); caracterizado por que el aparato (100) además comprende - un sistema ópticoproyector (20) para proyectar un plano dela lente optoajustable (11) en unplano exterior al aparato (100); y por que - la señal periódica tiene una amplitud tal que produce una amplitud de la onda de potencia óptica periódica (200) correspondiente a una diferencia cromática de foco entre una primera longitud de onda y una segunda longitud de onda de luz visible que atraviesa la lente optoajustable(11). La invención también se refiere a un sistema para realizar medidas optométricas, y a un método para ajustar la potencia óptica de una lente ajustable. [ES]
