OPTOMETER USING VARIABLE LENS AND EYE EXAMINATION METHOD

摘要

An object of the present invention is to provide an ophthalmoscope and an optometry method using a variable lens for measuring the refractive power of the eye to be examined while changing the lens of the eye to be examined into a static or dynamic refractive state by adjusting the diopter of the variable lens. An ophthalmoscope using a variable lens includes: a measuring unit for measuring visual acuity information by irradiating light into the eye to be examined and processing the light reflected from the eye to be examined; And a lens adjustment unit for changing the lens of the eye to be examined into a static or dynamic refractive state; including, the lens adjustment unit, a gaze target for emitting light; And a diopter variable lens positioned at the other side of the gaze target by a certain distance. The optometry and optometry method using the variable lens of the present invention adjusts the diopter of the variable lens whose position is fixed without moving the target to be looked at by the eye to be examined, so that the lens of the eye to be examined can be easily made in a statically controlled state, and the refractive power of the eye to be examined can be accurately measured. can do.
