Adolescent precontrol varifocal eyeglasses

Abstract

The invention discloses adolescent precontrol varifocal eyeglasses. The adolescent precontrol varifocal eyeglasses comprise glass bodies provided with reflecting surfaces, the glass bodies comprise far visual areas, near visual areas, transitional visual areas and waggling blind areas, and the far visual areas have a fixed number of far degrees and are covered with release film; luminosity advancing belts which have smooth change in diopter are arranged from the far visual areas to the near visual areas, and the diopter of the glass bodies is gradually increased along the luminosity advancingbelts; first arc belts are arranged at the boundary lines of the transitional visual areas and the far visual areas; second arc belts are arranged at the boundary lines of the transitional visual areas and the near visual areas, the bending directions of the first arc belts and the second arc belts both tilt toward the centers of the glass bodies, and the curvature of the first arc belts is smaller than that of the second arc belts. By means of the adolescent precontrol varifocal eyeglasses, through the arrangement of the far visual areas, the transitional visual areas and the near visual areas which are connected with the correspondingly arc belts, the areas are reasonably arranged, the luminosity advancing belts which are natural in transition are adopted to gradually increase the diopter, the focus is steadily changed, and the problem in the prior art that eyestrain is caused when single focuses or irregular focuses are arranged is solved.

Description

technical field [0001] The present application belongs to the technical field of spectacle lenses, and in particular relates to pre-controlled zoom glasses for teenagers. Background technique [0002] Adolescents are a high-risk group of myopia, and frequent close-up use of eyes is the main reason. Glasses to prevent and control the progression of myopia in young people have become a very important research content in the optical industry. At present, the products on the market are mainly single-focus lenses and traditional progressive multi-focal lenses. . Its defects are mainly: [0003] 1: The main reason for teenagers to become a high-risk group of myopia is that they use their eyes at close range for a long time. We mainly use the distance power when fitting eyes in optical shops, that is, the power when seeing far away becomes the power of glasses, which is no longer enough. The needs of this group of people's eye habits, and the long-term reading, surfing the Inte...

AI Technical Summary

Problems solved by technology

[0003] 1: The main reason for teenagers to become a high-risk group of myopia is that they use their eyes at close range for a long time. We mainly use the distance power when fitting eyes in optical shops, that is, the power when seeing far away becomes the power of glasses, which is no longer enough. The needs of this group of people's eye habits, the long-term reading, surfing the Internet, homework, etc. of teenagers are the glasses that are in a state of tension and fatigue for a long time, which gradually deepens the prescription of the eyes.

Therefore, single focus lenses can no longer meet the needs of this group of people

[0004] 2: Due to the limitations of the design of the traditional progressive multi-focal lens, the addition degree (ADD) is generally fixed at 100 or 150 degrees for near use. If you look closely, you will see the invalid area and produce image distortion)
