Description

Technical Field

[0001] The present invention relates to the technical field of lenses, and specifically refers to a dual-effect composite microstructure lens for myopia prevention and delay. Background Art

[0002] With the development of electronic products in recent years, people are developing myopia from childhood to adulthood, and the number of myopic teenagers is increasing continuously, with myopia getting younger and the high myopia rate also rising continuously. Newborn infants are farsighted, and they become emmetropic as they grow. If the development is too fast, they will become myopic. Among them, the most influential factor in the occurrence and development of myopia is the rapid development of the eye axis. Therefore, corresponding myopia glasses lenses are also constantly evolving. Among them, defocus lenses are mainly suitable for teenage myopic patients. In terms of design, defocus lenses will cause the peripheral area of the lens to image in front of the retina, generating myopic defocus. For example, when light passes through the central area of the lens, it can be normally focused on the retina to ensure clear central vision. However, the peripheral light will be focused in advance after passing through the special optical area of the lens, forming a myopic defocus signal, just like giving a "signal" to the peripheral retina, telling it not to grow backward excessively, thereby potentially inhibiting the excessive growth of the eye axis. Because the excessive length of the eye axis is an important reason for the deepening of myopia.

[0003] The filling rate cannot be perfectly balanced with the visual subjective feeling and the prevention and control effect. For those with a high filling rate, the visual subjective feeling is not good, and it is not easy to adapt to wearing in the initial stage. For those with a low filling rate, the visual quality is good, but the prevention and control effect decreases. For static signals, when worn for a long time, the brain will produce adaptability, thereby reducing the prevention and control effect. Summary of the Invention
