Abstract
The invention relates to a device for measuring the subjective refraction of a person in near and/or medium vision, which comprises, according to the invention, for each eye of the person, a correction mounting (3) provided with at least one corrective lens, the correction mountings (3) being arranged such that the person looks through the lenses. The position of each correction mounting (3) is variable such as to adjust an angle (a) between the axes of the lenses.
