Background
Light is an important natural phenomenon because the eye can receive light emitted, reflected or scattered by objects so that humans can see a mottled, momentarily changing scene in the objective world. Visual stimuli that the visual system acquires from nature can be roughly divided into three categories: light perception (perception of object brightness), shape perception (perception of object shape and contrast), and color perception (perception of object color). At present, myopia is an international problem, and research on the formation principle of myopia and a method for treating myopia can be effectively realized by constructing a myopia animal model.
The two classic methods of the myopia induction animal model are form deprivation and optical defocusing, but the two methods mainly block the form sense in normal vision, and the experimental animal is required to be subjected to operation treatment or is worn with a shading structure for shading treatment in the forming process, the operation treatment mode of the mode easily causes irreparable damage to the experimental animal, or the experimental animal catches the shading structure due to discomfort in the shading structure wearing process to influence the myopia formation effect.
In recent years, attention has been paid to the relationship between color vision and myopia, and a myopia model caused by color vision imbalance has been successfully established. However, there is no universally accepted photopic dysopia myopia model as the most basic light sensation among the three major elements of visual perception. Therefore, the correlation between light sensation and myopia cannot be effectively studied.
Therefore, the inventor expects to design an instrument which can effectively stimulate the light sensation of an experimental animal to construct a myopia model.
