Photobiological Safety
Photobiological safety refers to the assessment and management of potential risks associated with exposure to light and optical radiation, ensuring that lighting and optical devices do not cause harm to human tissues, particularly the eyes and skin.
Key Aspects of Photobiological Safety
-
Eye Safety: Evaluates risks such as blue light hazard, photochemical damage, and thermal effects on the retina and cornea.
-
Skin Safety: Considers potential harm from ultraviolet (UV) or infrared (IR) radiation, such as burns or long-term cellular damage.
-
Standards and Regulations: Governed by international safety standards (e.g., IEC 62471), which classify light sources based on their potential hazards.
Why Is Photobiological Safety Important?
-
Consumer Protection: Ensures that everyday lighting, such as LEDs and screens, are safe for prolonged use.
-
Medical and Industrial Applications: Critical for the safe use of high-intensity light sources in surgical procedures, laboratory settings, and manufacturing.
-
Preventive Measures: Promotes the use of protective devices like filters, shields, or eyewear to minimize risks.
