Light that is visible to the human eye is referred to as visible light, comprised of the following colors: red, orange, yellow, green, blue, indigo, and violet.
Light that is visible to the human eye is referred to as visible light. However, invisible light, such as ultraviolet light is undetectable to the human eye. Blue light has been proved to be harmful to the eyes because it is the closest to ultraviolet light, with a wavelength between 380-490 nm.
The interval of this wavelength exhibits colors between blue and green, and causes blue light hazard on the retina.
The primary source of blue light is from computer screens. In contemporary times, humans frequently stress their eyes by staring at the computer or reading at close ranges for long periods of time, resulting in eye fatigue, blurry vision, myopia progression, dry eyes, and sore eyes. Exposures to blue light easily results in eye damage, especially inflicting macular degeneration.
As a response to abundant blue light in our lives existing in light equipment and computer screens, we recommend the use of filter lenses to avoid damage caused by blue light and subsequently reduce eye fatigue.
Among types of visible light, blue light possesses the most energy, thus, long-term exposure results in retina damage.
Recent medical research has verified that high energy blue light inflicts severe damage on the eyes, and increases the probability of macular degeneration.
