Abstract
Technology and light sources have experienced a revolution in recent years leading to the production of light emitting diode (LED) bulbs. White-light LED bulbs undergo degradation over time, leading to a rise in color temperature and a proportional increase in the emission of blue light from these bulbs. The small size of LEDs makes them the optimal choice for electronic devices because of their limited screen size. This means that blue light now exists in red, green, and blue solid-state illumination systems that did not exist a decade ago. It is debated if blue light induces toxic effects on the retina, but researchers agree that blue light negatively impacts the body’s circadian rhythm. Rather than focusing on electronic devices, individuals should be more concerned about blue light emission from the sun as it has been deemed the dominant source of low wavelength radiation. Blue light blocking devices have been introduced into the market claiming to prevent blue light induced retinal damage, improve sleep quality, and to lessen eye fatigue symptoms. However, these lenses may have been introduced to the market just as a commercial sales pitch if blue light is not toxic to the retina. This project suggests that the blue light lens is effective in blocking blue light significantly more than other filtering devices. Additionally, to combat disrupting the circadian rhythm, individuals should refrain from using electronic digital devices for two to three hours before going to bed or use a blue light filtering device.
