bracketing [brak´et-ing]
a technique, used in qualitative research, in which the researcher's knowledge about an experience is suspended or set aside.

bracketing 
A procedure used in subjective refraction in which large and equal steps of dioptric changes are made above and below the presumed correct answer, and then reducing the size of the dioptric changes and shifting the centre of the range, until the finest and just detectable blur is induced by equal steps above and below the refractive error. It is commonly used with patients with low vision and also to check the range of clear vision provided by a near addition.
