Embodiment Construction

[0042] Now in conjunction with accompanying drawing, invention is described in further detail. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic way, so they only show the composition related to the invention.

[0043] In describing the invention, it is to be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear ", "Left", "Right", "Vertical", "Horizontal", "Top", "Bottom", "Inner", "Outer", "Clockwise", "Counterclockwise", etc. Based on the orientation or positional relationship shown in the drawings, it is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood for limitation of the invention.

Abstract

The invention provides a multifunctional improved lens and a preparation method thereof. The multifunctional improved lens comprises a substrate sheet and a lens layer arranged on the outer surface ofthe substrate sheet, and a prescription luminosity area, a functional area and a peripheral visual field adjusting area are sequentially arranged on the substrate from the center to the outer edge. Through the lens layer arranged in the outer surface of the substrate sheet, the light receiving area and the light transmittance of the lens are improved, the imaging resolution of the lens is furtherimproved, and the visual definition is improved. The prescription luminosity area obtains a clear myopia correction effect through the optical center of the lens and the central fovea of macular; theretina is induced to extend to the imaging position of the functional area through the functional area, so that eye axis lengthening caused by outward extension of the retina is delayed; and the peripheral visual field adjusting area adjusts the imaging curvature, the image is completely presented on the retina, and the definition of the peripheral visual field is improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a multifunctional improved lens and a preparation method thereof. Background technique [0002] According to estimates, the global myopia population will increase to 5 billion in 2050, and one-half of the world's population will be troubled by myopia. The earlier myopia appears, the greater the chance of developing deep myopia and morbid myopia, and the higher the chance of serious complications. Therefore, when children and adolescents develop myopia, they should try to control the development of myopia. [0003] With the development of the economy, people are chasing a better quality of life, and the requirements for glasses are becoming more and more stringent. While correcting vision, they also hope that the lenses can have better visual clarity, clear peripheral vision, and can suppress the eye axis. The stretching can prevent further aggravation of myopia. The curr...
