Problems solved by technology

At present, the spectacle lenses on the market have a relatively single function, and only have the function of adjusting and gathering light. The adjustment and gathering of light cannot be carried out simultaneously, so it is still not effective in preventing young people from myopia.

specific Embodiment approach 1

[0014] Specific implementation mode one: as figure 1 As shown, the specific embodiment adopts the following technical scheme: it comprises a lens body 1, an upper light zone 2, a lower light zone 3 and a prism 4, and the lens body 1 is provided with an upper light zone 2 and a lower light zone 3, and the lower light zone 3 is arranged below the upper light area 2, and a triangular prism 4 with the base facing inward is arranged at the small flat top on the upper left side of the lower light area 3.

[0015] The lower light area 3 is a polygon similar to a trapezoid, and the two sides of the polygon are in the shape of arcs.

[0016] The lens body 1 is a resin lens, a PC lens or a yellow lens.

[0017] In the process of application, this specific implementation method first conducts functional assessment and visual function inspection on the condition of each vision patient, and then customizes it according to the needs, which is suitable for each vision patient, so as to prev...

specific Embodiment approach 2

[0019] Specific implementation mode two: as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that a triangular prism 4 with the base facing inward is arranged at the flat top on the upper right side of the lower light zone 3, and other components and connections are the same as those in Embodiment 1. same.

specific Embodiment approach 3

[0020] Specific implementation mode three: as image 3 As shown, the difference between this specific implementation and the first specific implementation is: the lower light area 3 is semicircular, and a triangular prism 4 is arranged on the upper right side of the lower light area 3. Other components and connections It is the same as the first embodiment.

Abstract

The invention discloses an optical lens for preventing myopia of students, relating to the field of optical technology. The optical lens comprises a lens body (1), an upper optical zone (2), a lower optical zone (3) and a triple prism (4), wherein the upper optical zone (2) and the lower optical zone (3) are arranged on the lens body (1), the lower optical zone (3) is arranged below the upper optical zone (2), and the triple prism (4) with an inward substrate is arranged at a small flat top above the left side of the lower optical zone (3). The optical lens has the beneficial effects that the structure design is reasonable and novel, eye axis increase can be effectively slowed down, myopia progress is controlled, paracentral defocus and form deprivation are alleviated, near distance seeing for a long time is comfortable, adjustment and focusing, caused by near seeing of the students, can be reduced, the optical lens is suitable for visual physiology of the students during near seeing, myopia occurrence and progress can be effectively prevented, the myopia diopter of adolescents and children can be gradually reduced by proper adjustment of a dioptric system, and therefore, the optical lens is an ideal product for preventing juvenile myopia.

Description

Technical field: [0001] The invention relates to a lens for preventing and treating myopia for students, which belongs to the field of optical technology. Background technique: [0002] With the progress of society and the development of science, the load of young people using their eyes at close range is increasing, the incidence of myopia and the deepening of myopia diopter are becoming more and more serious, and even the country will face the danger of having no soldiers to recruit. This phenomenon has caused It has attracted the attention of the whole society. Optometry experts and medical experts have conducted a lot of investigations and discussions. However, there is no real ideal treatment method for the myopia of teenagers and children. The experts and scholars engaged in the prevention and treatment of myopia in my country generally recognize that it is not suitable for teenagers. The occurrence and development of myopia can only treat accommodative myopia and preven...
