Description

Read-write auxiliary equipment and control method thereof Technical Field The present invention relates to the field of ophthalmic optics, and in particular to a read-write auxiliary device, a control method of a read-write auxiliary device, a computer readable storage medium and a computer program product. Background In recent years, teenager ametropia has become a public health problem to be solved in the global scope, and related research data show that the prevalence rate of myopia of the teenagers in the global scope continuously rises, and the myopia has a serious trend of low age and high degree, so that the myopia not only can lead to far vision reduction, influence the learning efficiency and daily life of the teenagers, but also can cause serious eye complications such as retinal degeneration, detachment and the like due to excessive increase of eye axes, and form a potential threat to eye health. The reason is that the long-time and short-distance reading and writing actions are one of the core causes for the occurrence and development of teenager myopia. However, the conventional desks or reading/writing tables used in families and schools are single in functional design, mainly focus on providing a flat supporting surface and realizing basic storage and arrangement, and generally lack consideration on optical quality of visual environment, eye behavior intervention and the like. Therefore, in order to meet the actual demands of teenager for preventing and controlling ametropia, various types of auxiliary reading and writing equipment with eye protection function are developed, and three types of auxiliary reading and writing equipment can be roughly classified into a far vision distance type, a contrast control type and a peripheral defocusing type according to the eye protection optical principle, but the three types of auxiliary reading and writing equipment can not provide effective ametropia preventing and controlling effects for long-time and short-distance reading and writing actions and simultaneously ensure clear and comfortable visual effects. In order to overcome the above-mentioned drawbacks of the prior art, there is a need in the art for a read-write auxiliary device, a control method of a read-write auxiliary device, a computer readable storage medium and a computer program product, which can provide an effective ametropia prevention effect for long-time and short-distance read-write actions of a user, and simultaneously ensure a clear and comfortable visual effect.

The light carrying the read-write content information is divided into two light paths through the half-reflection half-lens, the two light paths are subjected to color filtering treatment of different wave bands, and then the light of a specific wave band in one light path is subjected to blurring operation, so that light signals with color difference effects are formed after the two light paths are converged, the retina of a user is deceived, the illusion that the light of the specific wave band is in an excessive defocus state on the optical axis of the retina is generated, the growth of the eye axis of the user is further inhibited or promoted, and the clear and comfortable visual effect is ensured while the effective refractive error prevention and control effect is provided for the long-time and short-distance read-write behaviors of the user. The reading-writing auxiliary device comprises a half-reflecting half-lens, a first light path component and a second light path component, wherein the half-reflecting half-lens is used for reflecting first light rays provided by a reading-writing object to the first light path component, transmitting second light rays returned by the first light path component to the eyes of a user, transmitting the first light rays to the second light path component, and reflecting third light rays returned by the second light path component to the eyes of the user, the first light path component is used for reflecting the reflected first light rays to the second light rays, filtering light rays of a first wave band from the reflected first light rays and/or the second light rays, and modulating the reflected first light rays and/or the second light rays to a fir
