研究发现蓝光最严重损害眼睛分辨细节能力

乔治亚大学研究团队通过视觉实验发现，蓝光比其他波长的可见光对眼睛分辨细节的能力造成更大损害。1研究人员对60名年轻成人进行了测试，使用蓝光、绿光、黄光、红光和宽带光等多种光源进行对比，结果表明蓝光在视网膜上产生最大的光散射和光学像差。1这意味着参与者需要将两个光点分开更远的距离才能区分它们。1

虹膜色素沉着程度也影响光散射效应的程度。1研究发现，蓝色眼睛的人比棕色眼睛的人会经历更大的光散射。1乔治亚大学心理学系博士候选人Yaw Buabeng指出，"我认为蓝光过滤功能是有益的"，并建议长时间使用电子设备或进行户外活动的人使用蓝光过滤眼镜。1此外，研究还指出长期接触高能蓝光与黄斑变性相关。1

Researchers at the University of Georgia have determined that blue light causes greater damage to the eye's ability to discern fine detail compared to other visible light wavelengths.1 In a visual experiment involving 60 young adults, scientists tested how blue light, green light, yellow light, red light, and broadband light affected visual perception.1 The study revealed that blue light scatters the most on the retina, requiring participants to separate two light points at greater distances in order to distinguish them from one another.1

The research also identified iris pigmentation as a factor influencing the degree of light scattering.1 Individuals with blue eyes experienced greater light scatter than those with dark brown eyes, indicating that lighter iris pigmentation is associated with increased optical aberrations from blue light exposure.1

Yaw Buabeng, a doctoral candidate in the psychology department at the University of Georgia and lead researcher on the project, stated that "I think blue light filtering functionality is beneficial" and recommended blue light filtering glasses for people who spend extended periods using electronic devices or engaging in outdoor activities.1

Long-term exposure to high-energy blue light has been associated with age-related macular degeneration, suggesting potential health implications of prolonged blue light exposure.1
