As per the study 20% of the adults in USA suffer from some sort of seasonal affective disorder (SAD). While the other 80% experience the difficulty in falling asleep because of jet lag. In all cases, a bit of sunshine exposure not only affects the sleep cycles, but also leads to the depression, mood swings, and general fatigue.
The treatment of SAD or similar other cases involved prescription medications, taking OTC or seven sitting in front of the light boxes/ phototherapy lamps. The equipments used in this case are engineered for emitting the light at certain frequencies to mimic the sunlight & while sitting in front of any phototherapy device, light enters your eyes & then travels to the photoreceptors inside retinas. After the absorption of light by the photoreceptors, the signal travels to optic nerve along with the path to the pineal gland inside the brain that ultimately stops the excretion of sleep-inducing hormone-melatonin.
Today, the innovative engineering developed the portable eye wear that has the same effect as the traditional phototherapy equipments along with the more freedom to the body. Basically these devices have the specially designed LED light-bulbs that emit wavelength & light at a proper angle for producing the biological therapeutic effects.
