What is the consequence of viewing diffuse beams for extended periods?

Viewing diffuse beams for extended periods can result in large scale, lower level damage due to the cumulative effects of light exposure on the eyes. While diffuse beams are generally less hazardous than focused beams, prolonged exposure can still lead to potential damage to the retinal cells and surrounding structures. The retina is sensitive to light, and although the intensity may be lower, extended exposure can result in photochemical damage or thermal injury, leading to changes in vision or even permanent damage over time.

In the context of laser safety, it is crucial to recognize that even lower intensity light from diffuse sources can be damaging when viewed for prolonged periods. This understanding emphasizes the importance of adhering to safety protocols, such as limiting exposure time and using appropriate eye protection even when dealing with diffuse beam sources.
