The invention relates to an intelligent
optometry unit for the full-automatic tracking of
left eye and right eye and a working method of the intelligent
optometry unit. The
optometry unit comprises a core control module, a
server, a display module, a user terminal, a three-degree-of-freedom movement module, an observation window module and a projection mechanism, and the observation window module comprises an
infrared light detection mechanism and a photographing mechanism; the
infrared light detection mechanism is used for collecting field information to realize the detection and alignment functions of eye positions, and the projection mechanism comprises a COMS measurement camera, a visual chart, an LED
light source, an objective lens, a collimating lens, a semi-transparent and semi-reflective mirror A, a semi-transparent and semi-reflective mirror B, a condensing mirror group, a projecting mirror group and a differentiation plate. The observation window module and the
projector are combined, movement adjustment is carried out through the three-degree-of-freedom movement module, full-automatic optometry is achieved, accurate
refraction parameters can be automatically measured as long as a photographed person aligns the eyes to the observation window, and a report is formed and printed; optometry data are more accurate; and the detection efficiency is greatly improved.
