Blue light has already been found to disrupt sleep cycles and circadian rhythms, and prolonged exposure can contribute to eyesight problems and even loss. A new study between multiple institutions in China has found that repeated exposure to blue light may potentially cause a number of depressive symptoms. 

A recent study from the University of Toledo suggests that blue light from digital devices as well as the sun transform vital molecules in the sun’s retina into cell killers, according to phys.org. 

We recently investigated how everyday consumption of blue light impacts humans. Emphasizing the health risks of overexposure, we saw how LEDs can suppress blue light’s detrimental impact on humans.  In this post, we will explore how plants are affected by changes in the electromagnetic spectrum. With advancements in LED technology and increased spectral control, we can observe how colored light (specifically blue light) contributes towards plant growth and flowering. 

Although the use of blue light is an excellent solution to provide environmentally friendly lighting, it also poses a large number of health risks and disadvantages for humans. Before the creation of artificial lighting, overexposure to blue light was never an issue. Now, thanks to newer lighting technologies, our evenings and nights are flooded with illumination. As a result, excessive quantities of blue light and poor lighting, in general, can pose threats such as:
