Research has shown the benefits of blue-blocking glasses are immense. Benefit is to prevent damage to the DHA essential fat in your retinal pigmented epithelium which is responsible for converting sunlight into vital DC electric current your body needs. Additionally blue light will increase the distance of the proteins in the respiratory electron transport chain in your mitochondria making them far less efficient in producing mitochondria. Those who wore blue-blocking glasses from 6 p.m. to 8 a.m. for seven days had significant improvements in symptoms of mania compared to those who wore clear glasses. What's more, the improvements began after just three nights of use.
