Human eye diopter detection device

Abstract

The invention discloses a human eye diopter detection device. The human eye diopter detection device is specially provided with a telescopic relay system, a sent adjusting light signal can make the pupil of a to-be-detected person have set diopter, a detection light signal generated by a light ray generation system passes through a first spectroscope, then reaches the pupil with set diopter, and is scattered by the pupil to form a scattered light signal, the scattered light signal passes through the first spectroscope and the telescopic relay system and then forms a point-focused image of human eye wavefront in an imaging system, and through the analysis of a computer, diopter information of the pupil is obtained. According to the collected point-focused image of the human eye wavefront collected in real time, through the analysis of the computer, the diopter information of the human eye can be completely measured, and it is achieved that the diopter of the eye when the human eye observes objects at different distances is accurately measured.

Description

technical field [0001] The invention relates to the field of optometry, in particular to a human eye diopter detection device. Background technique [0002] Human eye diopter measurement can be used to check human eye vision and glasses. In the early days, the retinal retinoscopy method was used as an objective inspection method. The inspector held a retinoscope to emit a beam of light of a specific wavelength, which passed through the cornea, retina and other eyeball organs, and projected to the retina of the eyeball. The road reflects the eyeball. The examiner neutralizes the refractive error of the eyeball by adding lenses, and completes the detection of the diopter of the human eye; then, the automatic optometry instrument replaces the retinal retinoscopy method with the advantages of automatic, fast, accurate and comprehensive detection. In this state, the characteristics such as the diopter of the human eye can be measured more accurately. However, this type of auto...

Problems solved by technology

However, this type of automatic optometry instrument usually optically simulates a target at infinity in the system as a cloud system to induce the natural relaxation of the human eye, and then realize the diopter detection. At present, it can only measure the diopter when the ciliary muscle of the human eye is in a state of complete relaxation. and other information, but the diopter change information of the human eye when observing objects at different distances is powerless, and thus cannot make due information acquisition for the important ophthalmic parameter of ciliary muscle adjustment ability
