Abstract

The invention relates to a measurement device, in particular to an eye vision measurement device. The eye vision measurement device is accurate in measurement, practical, effective, and convenient to use. The eye vision measurement device comprises a base plate and the like. A measurement device body is arranged on the left portion of the base plate, and a pulling device is arranged at the bottom of the base plate. The eye vision measurement device has the effects of being accurate in measurement, practical, effective and convenient to use; manual control is adopted by the eye vision measurement device, and a user can sit on a chair comfortably for vision measurement; and through an illuminating lamp, the user can see a vision test chart more clearly, and thus measurement is more accurate and effective.

Description

technical field [0001] The invention relates to a measuring device, in particular to an eye vision measuring device. Background technique [0002] Vision is the ability of the retina to distinguish images. The quality of vision is judged by the ability of the retina to distinguish images. However, when the refractive media of the eye (such as cornea, lens, vitreous body, etc.) Eyes with a well-functioning retina can still lose vision. The opacity of the refractive medium of the eye can be treated with surgery, while the refractive errors need to be corrected with lenses. [0003] The visual acuity measured by the existing eye chart is inaccurate, inconvenient, and impractical. Therefore, it is urgent to develop an eye vision measuring device that is accurate, practical, effective, and convenient. Contents of the invention [0004] (1) Technical problems to be solved [0005] In order to overcome the inaccurate, inconvenient and impractical shortcomings of the eye visio...
