Technical Field
The invention relates to the technical field of medical instruments, in particular to a peripheral refraction detection auxiliary device for an optometry instrument.
Background
The peripheral refractive power is the refractive power in the peripheral visual field at an angle to the visual axis, i.e. the focused state of light rays at an angle to the visual axis after they are incident on the eyeball. According to the relative position of the focus of the incident light and the retina, the state can be classified into relative myopia, relative hyperopia and the like. The central and peripheral refractive powers are the most important indexes for completely evaluating the human eye refractive state. The difference between the peripheral power value and the central power increases toward the periphery, and higher-order aberrations such as astigmatism, spherical aberration, and coma aberration occur.
The peripheral refractive power has important significance in ophthalmology clinic and scientific research, and is a common detection project for myopia research and pediatric ophthalmology at present. (1) Peripheral refractive power is an important factor affecting myopia progression. Studies have demonstrated that: the myopic eye has different peripheral refractive states from that of the emmetropic eye and shows relative hypermetropia at the periphery, and the stimulation of the peripheral defocus can cause the axial growth of the eye, thereby causing the myopia to progress; although the correction with glasses focuses the light in the visual axis direction on the macula, myopia progresses because the periphery is still in a relatively distant vision state.
