A virtual reality instrument measures the refraction and aberrations of the eye in an automatic way, and includes a portable part which is a virtual reality headset foreseen of a detailed screen per eye and at least one background screen, both virtual. The detailed screen has a resolution multiple times the foveal resolution of the eye and the background screen has the resolution similar to the peripheral resolution of the eye. The virtual reality instrument also includes at least one pupil camera, a system to manipulate the phase of the light coming from the detailed screen, a wavefront sensor and light source to measure the wavefront using a wavelength of at least 400 nm.

Virtual reality instrument for the automatic measurement of refraction and aberrations of the eye

An instrument measuring optical properties of an eye in an entire field of vision, including refraction and aberrations, including: a frame mounted on an ophthalmologic table that can be oriented in three perpendicular directions X, Y, Z; a support surface for a head of the subject; a hot mirror; a long mirror; an illumination sub-assembly including a fiber optic head; a lens; a diaphragm; a beam splitter; and a measurement sub-assembly with two lens and two mirrors; a camera including a matrix of micro-lenses on the inlet of camera, the camera being placed on the focal plane of the micro-lenses; the frame including a motor, a shaft of which rotates in the Y direction, to which an arm is attached that can rotate on the shaft; components of the illumination sub-assembly, components of a measurement sub-assembly, and the camera with the matrix of micro-lenses being mounted on the arm.
