A device for determining of the distance to an object and its motion with non-contact method. Designed device also allows an additional function, namely, to measure the distance to the further point of clear vision of the human eye and to measure the value of eye refractive error. In this case this distance meter turns into ophthalmic refractometer.

The method of determination of parameters of clinical focus of presbiopic eye is based on the analysis of three-dimensional distribution of luminosity in the zone of geometrical back focus of the optical system of eye.

For the purpose of eye aberration correction with the special contact lens or intraocular lens it is necessary to be informed about eye refraction aberrational component. This information can be acquired by using of device based on modified Foucault knife method. For this purpose we propose to use the optical-electronic system which allows to detect and fix the pupil plane isodiopter zones.
