The American Academy of Ophthalmology defines blue light as the high-energy visible light that stimulates the retina and is emitted from digital screens and artificial lighting.
The underlying reason for the use of orange lenses lies in the characteristics of blue light. Blue light has shorter wavelengths, making it higher in energy compared to other visible colors. Prolonged exposure to this energy can lead to digital eye strain, which manifests as symptoms like dry eyes, irritation, and fatigue. Additionally, blue light exposure, particularly in the evening, can interfere with the body’s production of melatonin, a hormone that regulates sleep.
In technical terms, spectrums of light are categorized by their wavelength. Blue light typically ranges from 380 to 495 nanometers. Orange lenses act as a filter, reflecting or absorbing these wavelengths, thereby minimizing their impact on the eyes. The process involves the selective absorption of blue light, allowing only longer wavelengths to pass through, which are less likely to cause strain.
Specific actions, such as staring at screens for prolonged periods or using digital devices before bedtime, can exacerbate the effects of blue light exposure. For example, a person working long hours on a computer without breaks will likely experience increased discomfort and fatigue. Similarly, using devices at night can delay sleep onset due to blue light’s interference with melatonin production.
In summary, orange lenses in blue light glasses provide a practical solution to mitigate the effects of blue light exposure, contributing to comfort and better sleep quality.
