Abstract
A method and associated instrument in which an optical system is switched from a first to a second refractive power states, to provide a first, and then a second refraction correction to an eye of a subject, the switching being carried on without interrupting a light beam coming from a target object and transmitted by the optical system to the eye of the subject. The switching is carried on in order to circumvent an intermediate refraction correction that is in between said first and second refraction corrections, or with a speed higher than a given limit.
