防蓝光产品热销 眼科专家厘清认知误区

Core Viewpoint - The article discusses the growing concern over blue light exposure from electronic devices and the proliferation of blue light protection products, while highlighting the misconceptions consumers have about their effectiveness and the importance of good eye care habits over reliance on such products [1][3][7]. Group 1: Blue Light Understanding - Blue light is a visible light with a wavelength range of 400nm-500nm, where long-wave blue light (greater than 455nm) is beneficial for regulating biological rhythms and improving mood, while short-wave blue light can be harmful only under high intensity and prolonged exposure [1][2]. - The energy characteristics of blue light mean that only when the irradiance exceeds safety thresholds can it potentially damage retinal cells, with normal electronic device screens operating well below these thresholds [2]. Group 2: Effectiveness of Blue Light Protection Products - There is currently no reliable scientific evidence that blue light protection products can effectively prevent myopia or slow the progression of eye diseases, and their effectiveness may only provide slight relief from eye fatigue compared to adjusting screen brightness and maintaining proper distance [3][4]. - A study revealed that among nine different blue light protection films, four had a blue light blocking rate of less than 20%, with the best performing product only blocking 52.1%, indicating widespread ineffective protection in the market [3]. Group 3: Eye Care Recommendations - Good eye care habits account for 90% of effective eye protection, with outdoor activities and proper eye usage being crucial, while blue light protection products serve as a minor supplementary measure [6][5]. - Experts recommend the "20-20-20" rule, increasing outdoor activity, optimizing visual environments, and regular eye check-ups as essential components of a comprehensive eye care strategy [6]. Group 4: Role of AI in Health Management - AI applications like Ant Financial's "Ant Aifu" are emerging as intelligent partners in personal health management, helping users cultivate healthy habits, including eye care, through features like health diaries and goal setting [7]. - The article emphasizes that consumers should focus on developing healthy lifestyles rather than succumbing to "blue light anxiety," advocating for proactive health management based on scientific understanding rather than reliance on single products [7].
