Utility
Vision measurement device and method of measuring vision using the same
19 Jul 22
A vision measurement device includes an eyepiece with a lens; an outer tube connected to the eyepiece including a target having a predetermined pattern, the target being movable along an optical axis of the lens with respect to the outer tube; a diopter indicator with an indicating portion and a pointing portion; where during the movement of the target with respect to the outer tube along the optical axis of the lens, one of the indicator portion and the pointing portion moves along with the target with respect to the outer tube while the other of the indicator portion and the pointing portion does not move, and when an eye is capable of clearly seeing the predetermined pattern on the target through the eyepiece, the value of the scale indicated by the pointing portion corresponds to the diopter of the eye.
