“多用洗眼液”是护眼神器还是智商税？

Core Viewpoint - The article discusses the rising popularity of eye wash solutions among young people, questioning their effectiveness and safety, and emphasizing that the eyes have a natural protective barrier that negates the need for such products [1][11]. Group 1: Product Overview - Various brands of eye wash solutions are available on online platforms, containing ingredients like Vitamin B, trehalose, and taurine, with some claiming to include "ergothioneine" for deep cleaning and repair [3][5]. - In addition to eye wash solutions, "eye care sprays" are also being marketed, claiming to clean the eyes with similar ingredients [8]. Group 2: Medical Perspective - Medical professionals assert that the use of eye wash solutions lacks scientific backing, as the eyes possess a self-cleaning ability through tears, which consist of a complex three-layer structure [11][12]. - The use of eye wash solutions may dilute tears and disrupt the microenvironment of the eye surface, potentially causing more harm than good [12][16]. Group 3: Recommendations - Medical experts recommend avoiding self-use of eye wash solutions and suggest consulting an ophthalmologist for any eye issues, as these products do not address all discomforts and may lead to further complications [14][18]. - In cases where foreign objects enter the eye, medical washing involves a systematic process using sterile solutions, which differs from the casual use of commercial eye wash products [21][23].
