Measurement of Antioxidant Activity
Since the creation of life on the Earth, our skin has been exposed to different levels of visible and invisible light. Over the past decades, due to inevitable consequences of industrialization, modern life and major changes in the life style of large segments of the population of developing and developed countries, humans are not exposed to adequate levels of natural light during the day but are overexposed to relatively high levels of artificial light at night. Recent advances in the technology of light-emitting diodes (LEDs) have led to their widespread use in lighting.
Low energy consumption, small size and long lifetime are among the basic advantages of LEDs over the old high energy consuming incandescent light sources. LEDs are currently used in a wide variety of applications ranged from traffic signals to camera and smartphone flashes. The widespread application of LEDs and the rapidly increasing use of smartphones, tablets, laptops and desktop computers have led to a growing concern over the safety of these light sources which their peak emission lies in the blue region (400-490 nm).
