Wear Blue Light Cutting Glasses at Night Can Help to Improve Sleep Quality

Scientists warned that intensive exposure of blue light through heavy usage of electronical devices such as mobile phones and tablets might affect sleeping quality. A new study showed that by limiting or blocking evening exposure to light-emitting screen for one week, sleep quality for teenagers can be improved. The collaborative study by the Netherlands Institute of Neuroscience, the Amsterdam UMC and the Dutch National Institute for Public Health and the Environment indicates that by simply limiting exposure to blue-light emitting devices in the evening, adolescents can ...

Exposure to White Light at Night Could be Harmful for Cardiac Patients

Researchers at West Virginia University found that exposure to white light at night could impact recovery of cardiac patients and dimming the light can reduce the damages. With the results published in Experimental Neurology, the research team, led by Randy Nelson, who chairs the Department of Neuroscience in the WVU School of Medicine, linked white light at night to inflammation, brain-cell death and higher mortality risk in cardiac patients. (Image: Pixaby) The researchers re-created cardiac arrest in animal models and divided the models into three groups that w...

ProLight Introduces Long Wavelength Blue LED Series for Human Centric Lighting

Recently, the topic of blue light harming the eyes has been taken seriously and new LED development has focused on reducing the negative effect of blue light on the body. Theoretically, blue light wavelength ranges from 420nm to 480nm. According to one of the reports done by International Electrotechnical Commission (IEC), the shorter wavelength range of blue light from 415nm to 460nm is most likely to damage the eye. The report also mentioned that when exposed to these short blue light ranges, the risk of getting eye disease such as Macular degeneration will increase. Most...

The Future of Blue Light Considering Its Health Concerns

It was 1958, when J. Woodland Hasting and Beatrice M. Sweeney wrote the paper entitled "A persistent diurnal rhythm of luminescence in gonyaulax polydra".  Paper concluded on how lights of different wavelength have the ability to change flow of a hormone named melatonin and hence affecting human body clock, also known as circadian rhythm (as shown in Fig 1).The most powerful wavelength to do so was found to be that of blue.
