T/JGE 0120-2024 Jiangxi Green Ecology Single Light Old Age Sight Deficiency Lens

Scope

Main technical content: The advancedness of the product indicators in this document is explained as follows: - In the quality-leading indicators of the "Jiangxi Green Ecology Single Vision Presbyopia Glasses", the difference in focal length between the two lenses is ≤0.10 m-1, the deviation of the horizontal distance between the optical centers is ±1.0 mm, and the deviation of the horizontal distance on one side of the optical center is ±0.5 mm. These requirements are stricter than those in GB/T 13511.3 "Fitted Glasses - Part 3: Single Vision Presbyopia Glasses", which stipulates that the difference in focal length between the two lenses should be ≤0.12 m-1, the deviation of the horizontal distance between the optical centers should be ±2.0 mm, and the deviation of the horizontal distance on one side of the optical center should be ±1.0 mm. At the same time, the requirement for focal length deviation is increased to ≤±0.09 m-1. - In the quality-leading indicators of the "Jiangxi Green Ecology Single Vision Presbyopia Glasses", the transmission ratio (in the visible spectral range) is ≥88%, which is higher than the requirement in GB 10810.3 "Eyeglass Lenses and Related Eyewear Products - Part 3: Transmission Ratio Specifications and Measurement Methods" that the transmission ratio (in the visible spectral range) should be >80%. At the same time, the requirement for the relative deviation in the transmission ratio between the two lenses is increased to ≤10%.
