Abstract The increasing prevalence of LED lighting has raised concerns regarding blue light hazards to human eyes. Traditional laboratory-based photobiological safety testing systems, while accurate, often lack portability and ease of use in diverse application scenarios. This paper discusses the development of a Portable Retinal Blue Light Hazard Tester, specifically the LISUN EN62471-P model, wh...
With the rapid advancement of digital technology and information systems, computers have become an integral part of both our work and personal lives. While computers offer significant convenience, they have also led to an increase in eye strain and visual impairments. As a result, protecting eye health has become a major concern. The primary concern regarding computer-induced eye strain is blue li...
Light-mediated biological effects refer to the physiological changes in the human body caused by exposure to light radiation. The mechanism of light-mediated biological effects varies depending on different pathways. Firstly, light can directly act on the human eye, transmitting visual information and inducing visual effects. Secondly, light can regulate the body’s physiological rhythms by a...
The danger of blue light is pervasive. Sunlight is the most common source of indoor exposure, although you may also obtain it outdoors. A blue light tester device has measured this blue light hazard. In today’s technologically advanced society, many individuals spend most of their waking hours in front of a screen. You’re exposed to artificial blue light when staring at a computer scre...
