Effect of blue light on modern society

health sciences

The blue light that goes from our eyes reaches the retina and melanopsin, which is a photopigment in the retina, used for controlling the circardian rhythm and the sleep-wake cycle, showcases one of the most significant and common effects of our blue light. This gives rise to the prevalence of sleep disorders, the poorer sleep quality linked to extreme exhaustion, and the disruption of social and familial relationships. Blue light, however, can be advantageous if consumed in the morning hours; it has been seen to relieve symptoms in people with neurocognitive diseases like Alzheimer's disease. Blue light increases dopamine release in the short term, while exposure to light for a prolonged time can reverse the effect and results in symptoms for example anxiety, mood swings, lack of insight, and self-awareness. To prevent the dangerous effects of blue light, one needs to be aware of the equipment that affects us and the primary "enemy" present in our daily lives, right next to us: smartphones, tablets, and televisions.
