Description

technical field [0001] The invention belongs to the field of vision tools, and in particular relates to a vision aid. Background technique [0002] The visual system of the human eye is composed of cornea, aqueous humor, lens, vitreous body, retina and optic nerve. The light entering the eye is refracted by the refractive system of the eye and then focused on the retina. After the visual cells on the retina feel the light, the visual information is transmitted to the visual cortex, and vision is formed after processing. [0003] Vision health There are myopia, hyperopia and visual impairment caused by various diseases. [0004] According to the cause of injury, it is divided into traffic accident injury, fall injury and blow injury, among which the most common is traffic accident injury. Due to the anatomical structure and physiological characteristics, more than 90% of the optic nerve injuries are indirect injuries of the optic canal. The direct injury caused by the stab...
