Blue Light Blocking Eyeglasses

Blue light exposure at night has been proven to have an adverse effect on your body’s internal clockwork. It throws the circadian rhythm out of course, and the consequences might lead to grave health issues. But where is blue light? We come into contact with this artificial light readily because it is emitted by electronics and energy-efficient lightbulbs.

Even though there’s no clear reason why light exposure at night is not good, there is indication that it suppresses the secretion of melatonin, a hormone that influences circadian rhythms. Low melatonin levels have been associated with cancer.

While light of any kind can suppress the melatonin secretion, blue light at night does so more powerfully. Fluorescent lightbulbs and LED lights may be more energy-efficient than old-fashioned incandescent lightbulbs but they also tend to produce more blue light.
